INTRODUCTION

I. INTRODUCTION
BACKGROUND
Part D sponsors, that is, Prescription Drug Plans (PDPs) and Medicare Advantage Prescription
Drug Plans (MA-PDs), must submit a separate bid to the Centers for Medicare & Medicaid
Services (CMS) for each prescription drug plan that they intend to offer Medicare beneficiaries.
This includes Part D plans without a corresponding Medicare Advantage (MA) plan such as
Section 1876 cost plans, Section 1833 cost plans, and Programs of All-Inclusive Care for the
Elderly (PACE) plans.
Note that, an MA organization (MAO) may offer private fee-for-service (PFFS) and Religious
Fraternal Benefit PFFS plans without Part D coverage. However, if an MAO offers, in a given
MA service area, at least one benefit plan of any other plan type, at least one benefit plan in
such service area must include Part D coverage.
Organizations must submit the information via the CMS Health Plan Management System
(HPMS) in the CMS-approved electronic format— the Prescription Drug Bid Pricing Tool
(BPT).
Each bid submission must include an actuarial certification and supporting documentation as
described in Appendix A and Appendix B, respectively.
The submitted bids will be subject to review and audit by CMS or by any person or
organization that CMS designates. As part of the review and audit process, CMS or its
representative may request additional documentation supporting the information contained in
the BPT. Organizations must be prepared to provide this information in a timely manner.
These bid instructions provide details on the bid submission elements required by 42 CFR
423.265.

PRICING CONSIDERATIONS

II. PRICING CONSIDERATIONS
BIDDING/PRICING APPROACH
By statute, the bid must represent the revenue requirement of the expected population.
Therefore, in most circumstances, Part D sponsors must use credible bid-specific experience in
the development of projected allowed costs. This approach does not preclude Part D sponsors
from reaching specific benefit and premium goals; the gain/loss margin guidance allows
sufficient flexibility to achieve pricing targets provided that the overall gain/loss margin meets
the requirements in the guidance and that anti-competitive practices are not used.
It is important to note the distinction between reporting base period experience data in
Worksheet 1 and projecting credible data for pricing. Base period experience must be reported
at the plan level if the plan existed in CY2021, regardless of the level of enrollment. This
experience must also be projected in Worksheet 2 and assigned an appropriate level of
credibility by the certifying actuary. Data may be aggregated for determining manual rates to
blend with partially credible projected experience rates or to account for significant changes in
enrollment from the base period to the contract year.

Actuarial Equivalence

Actuarial equivalence must be demonstrated for plan benefit types other than Defined Standard
(DS).
When the plan benefit type is Actuarially Equivalent (AE), three tests must be satisfied on
Worksheet 4, Section IV, lines 16 through 18 to demonstrate actuarial equivalence:
•
•
•

The average coinsurance percentage for amounts between the deductible and the initial
coverage limit (ICL) must be actuarially equivalent to 25 percent.
The average coinsurance percentage above the catastrophic limit must be actuarially
equivalent to the percentage for DS coverage.
The average coinsurance percentage for amounts between the ICL and catastrophic
limit must be actuarially equivalent to the percentage for DS coverage.

CY2023 Part D BPT Instructions

Page 6 of 86

PRICING CONSIDERATIONS

When the plan benefit type is Basic Alternative (BA) or Enhanced Alternative (EA), six tests
must be satisfied to demonstrate actuarial equivalence on Worksheet 5, Section VI, lines 1
through 6:
•
•
•
•
•
•

The value of total coverage is at least actuarially equivalent to DS coverage.
The alternative unsubsidized value of coverage is no less than the DS unsubsidized
value of coverage.
The average alternative benefits for beneficiaries with allowed drug costs at the ICL are
not less than the average DS benefits at the ICL.
The deductible is not greater than the DS deductible.
The average alternative catastrophic cost sharing is not greater than the average DS
catastrophic cost sharing.
The average coinsurance percentage for amounts between the ICL and catastrophic
limit is at least actuarially equivalent to DS coverage.

Base Period Experience

The experience data must be based on a calendar year 2021 incurred period with at least
30 days of paid claim run-out; 2-3 months of paid claim run-out is preferable. Further, the
enrollment data for the Part D bid in an MA-PD plan must reflect the same underlying
population as that for the corresponding MA bid.
Worksheet 1 must be completed with data for the plan ID. Note that these data—
•
•

•

•

•

•
•
•

Must be submitted in Worksheet 1 for any plans with experience data for 2021,
regardless of the level of enrollment.
Must reconcile in an auditable manner to the plan-level Prescription Drug Event (PDE)
data submitted to CMS for payment and reconciliation and the Part D sponsor’s audited
financial statements.
Must include accepted PDEs, rejected PDEs that are expected to be accepted by CMS
upon resubmission, adjustments for Plan-to-Plan (P2P) transactions and, if appropriate,
transfer of over-the-counter (OTC) drug data from the base period experience to the
non-benefit expense component. The impacts of each of these considerations must be
quantifiable and must not be included in the completion factor.
Must be reported without adjustment. Adjustments may be made in Worksheet 2,
Sections II and III to accommodate population, benefit design or other changes from the
base period to the contract period.
May be reported in aggregate for a number of plans only when there are enrollment
changes associated with the dissolution of a plan and the retained members are crosswalked into existing plans in the same contract or across contracts. Each contract-plansegment ID must be identified in Section II, line 5.
Must be provided for plans acquired by the Part D sponsor.
May not be used to aggregate data from a number of plans in order to achieve
credibility.
Must be reported in total at the plan level for every contract-plan ID when plans are
aggregated; do not include partial plan experience on Worksheet 1.

CY2023 Part D BPT Instructions

PRICING CONSIDERATIONS

•

May be reported on more than one bid when plans are aggregated, depending upon how
enrollment changes are processed.
Data Aggregation

The requirements for reporting base period data for cross-walks and enrollment shifts
depend on—
•

How enrollment changes are processed.
◦ In these Instructions, the term “formal cross-walk” refers to the cross-walk
process submitted in HPMS for plan consolidations (that is, consolidated
renewals), whereby members are automatically moved from one plan to
another (that is, one plan only). Without an HPMS cross-walk in place,
members are dis-enrolled from the terminating plan and must actively select
to enroll in a new plan of their choosing.
◦ Medicare Advantage and Prescription Drug (MARx) enrollment transactions
are used to automatically move members from one plan to more than one
plan, for example, when the service area of one or more plans is redefined.
◦ For more information about cross-walks, see the May 18, 2016
memorandum released via HPMS titled “Process for Requesting an HPMS
Crosswalk Exception for Contract Year (CY 2018).”

The requirements for reporting base period data for crosswalks and enrollment shifts are
described below.
✓ Rule 1 – Cross-walks

Base period data for more than one CY2021 contract number-plan ID must be
aggregated and reported on Worksheet 1 of the plan into which the members are
cross-walked only in the following circumstances:
•

When two or more plans are consolidated and the members are cross-walked
into an existing or new plan under a formal cross-walk.

Rule 1 applies when members are cross-walked within the same contract and when
members are cross-walked between contracts in accord with limited exceptions
described in CMS annual renewal and non-renewal guidance.
✓ Rule 2 – Enrollment Shifts

Base period data for more than one contract number-plan ID cannot be aggregated
and reported on Worksheet 1 in the following circumstances:
•
•

When an existing member chooses to enroll in different plans.
When enrollment changes do not involve a cross-walk whether or not a plan is
terminated.

✓ Rule 3 – Partial Experience

Base period experience must be reported in total at the plan level for every contractplan ID; do not include partial plan experience on Worksheet 1.

CY2023 Part D BPT Instructions

Page 8 of 86

PRICING CONSIDERATIONS
✓ Rule 4 – Two-Year Perspective

Members may be cross-walked each contract year. For BPT reporting purposes, the
actuary must consider the cross-walks from the base period to the contract year (that
is, from CY2021 to CY2022 and from CY2022 to CY2023).
Example 1: Formal Cross-walk

A Part D sponsor offers plans 001, 002 and 003 in CY2021 and CY2022 and
plans 002 and 003 in CY2023. Plan 001 is consolidated and the membership is
formally cross-walked into plan 003 for CY2023 in accord with limited exceptions
described in CMS annual renewal and non-renewal guidance. Base period
experience must be reported on Worksheet 1 of the CY2023 BPT as follows:
•
•

For plan 002, report aggregate base period experience for plan 002 (Rule 1 and
Rule 3).
For plan 003, report base period experience for plans 001 and 003 (Rule 1 and
Rule 3).

Example 2: Formal Cross-walk and Enrollment Shift

A Part D sponsor offers plans 001, 002 and 003 in CY2021 and CY2022 and
plan 003 and new plan 004 in CY2023. Plan 001 is consolidated and the
membership is formally cross-walked into plan 003 for CY2023 as submitted in
HPMS. Plan 002 is terminated for CY2023 and the certifying actuary expects the
membership in plan 002 to enroll evenly between plans 003 and 004; however, there
is no formal cross-walk or approved cross-walk exception in place. Base period
experience must be reported on Worksheet 1 of the CY2023 BPT as follows:
•
•

For plan 003, report base period experience for plans 001 and 003 (Rule 1 and
Rule 3).
For plan 004, do not report base period experience (Rule 2). Data aggregation is
not allowed.

Example 3: Cross-walks in Successive Years

A Part D sponsor offers plan 001 with 100 beneficiaries and plan 002 in CY2021. In
CY2022, 50 beneficiaries stayed in plan 001 and 50 beneficiaries were cross-walked
into plan 002 via MARx enrollment transactions. In CY2023, 25 beneficiaries
stayed in plan 001 and 25 beneficiaries were cross-walked into plan 002 via MARx
enrollment transactions. Base period experience must be reported on Worksheet 1 of
the CY2023 BPT as follows:
•
•

For plan 001, report base period experience for plan 001 (Rule 3).
For plan 002, report base period experience for plans 001 and 002 (Rule 1,
Rule 3, and Rule 4).

When using PDE data, actuaries must be familiar with the process by which the
PDE transactions are developed from claims data and with the timing of the
adjustment and deletion processes to ensure that the final transaction is accurately
summarized. This process includes, but is not limited to, consideration of rejected
PDEs that are expected to be accepted by CMS upon resubmission, adjustments for
Plan-to-Plan transactions and, if appropriate, transfer of over-the-counter drug data
from the base period experience to the non-benefit expense component. It is
important to note that a PDE maps to one script throughout the BPT regardless of
the number of days for which the prescription is dispensed.
Coverage in the Gap
Medicare Coverage Gap Discount Program (CGDP)

The following guidelines apply to all Part D bids:
•

Applicable drugs under the Medicare CGDP are defined as those that are on the
plan’s formulary or are treated as if on formulary through the exceptions process
and are approved under a new drug application (NDA) under Section 505(b) of

CY2023 Part D BPT Instructions

Page 10 of 86

PRICING CONSIDERATIONS

•
•

•
•
•

•

the Federal Food, Drug and Cosmetic Act or, in the case of a biologic, licensed
under Section 351 of the Public Health Service Act. In general, this definition
applies regardless of the drug’s placement on the plan-specific formulary.
Only those applicable Part D drugs covered by a manufacturer discount
agreement are eligible for coverage under the program.
In CY2022, beneficiary cost sharing for applicable drugs is 25 percent of the
negotiated price plus 25 percent of the dispensing and vaccine administration
fees, if any; the Part D sponsor’s liability is 5 percent of the negotiated price
plus 75 percent of the dispensing fee and vaccine administration, if any. Ninetyfive (95) percent of the negotiated price of the applicable drug and 25 percent of
the dispensing fee and vaccine administration fee, if any, must be reported as
beneficiary cost sharing in the bid.
Coverage gap discounts begin when the beneficiary exceeds the plan-specific
ICL.
The administrative costs associated with administering the program must be
included in the non-benefit expense component of the bid.
The manufacturer discount amounts received under this program are not direct
and indirect remuneration because they do not decrease the drug costs incurred
by the Part D sponsor. Therefore, the manufacturer discounts must not be
reported as rebate amounts in the bid.
Applicable drugs must be reported as brand drugs in the bid.

Generic Drugs

The following guidelines apply to all Part D bids:
•

•
•
•

In the coverage gap and throughout the BPT, a drug is considered a generic
drug, or non-applicable drug, if it is not defined as an applicable drug under the
Medicare CGDP. In general, this definition applies regardless of the drug’s
placement on the plan-specific formulary.
In CY2022, beneficiary cost sharing is 25 percent and the Part D sponsor’s
liability is 75 percent.
Generic (non-applicable) drug coverage in the gap begins when the beneficiary
exceeds the plan-specific ICL.
Non-applicable drugs must be reported as generic drugs in the bid.

Pricing Considerations

Part D sponsors must model the impact of coverage in the gap on the DS benefit and
alternative benefit (AE, BA or EA), if applicable.
•
•

While coverage in the gap does not change the TrOOP threshold, it will affect
the point at which the beneficiary reaches the TrOOP threshold for catastrophic
coverage.
The changes to projected average allowed amounts from the base period to the
contract year that are expected to occur as a result of reduced beneficiary cost
sharing must be reflected in the “Other Change” components of utilization and
unit cost trend factors on Worksheet 2.

CY2023 Part D BPT Instructions

Page 11 of 86

PRICING CONSIDERATIONS

•

The impact on the Federal Reinsurance PMPM must be reflected in line 5,
column m of Worksheet 3.
The following guideline applies when the type of coverage is AE, BA or EA:
◦ When an alternative coverage is modeled, members must be reported in the
claims interval in which they were reported under DS coverage even though
their total drug spending may be different because of the impact of the
alternative benefits.
The following guideline applies when the type of coverage is EA:
◦ When an EA plan offers coverage in the gap that exceeds the DS coverage:
▪ Report the drugs on the “enhanced” tiers based on the plan-specific
formulary.
▪ Report all other drugs based on the definition of applicable and nonapplicable drugs.

Credibility

CMS does not permit adjustments to the credibility percentages on Worksheet 2 for the purpose
of modifying the manual rate. For example, do not adjust the credibility percentages in the BPT
as an equivalent alternative to removing the base period experience from the manual rate
development.
The following credibility guidance in this section is provided as a resource to certifying
actuaries, not as a requirement.
Information on the development of the CMS guidelines for full credibility can be found on the
“Medicare Advantage Rates & Statistics” page of the CMS website at https://www.cms.gov/
Medicare/Health-Plans/MedicareAdvtgSpecRateStats/Bid-Pricing-Tools-and-InstructionsItems/BidGuidance.html.

Overriding the CMS Formulas for Partial Credibility

The following guideline is applicable only to the CMS claims and risk score credibility
formulas presented above; such guideline may not be suitable for any alternative
credibility formula. If the CMS formula for partial credibility is applied and the
resulting credibility is—
•
•

Less than or equal to 20 percent, then the actuary may override the computed
credibility with 0 percent credibility.
Greater than or equal to 90 percent, then the actuary may override the computed
credibility with 100 percent credibility.

Decreased Initial Coverage Limit

Part D sponsors that are decreasing the ICL must modify the pricing of the benefit in the BPT.
Specifically:
Worksheet 6, column k, lines 1 through 8 and 19 through 26

Enter the total cost sharing for allowed costs up to the DS ICL of $4,430 by point-ofsale (retail or mail order as defined by the PBP) and type of drug for each line. Total
cost sharing is the sum of (i) the amounts calculated based on the cost-sharing structure
of the alternative coverage up to the decreased ICL and (ii) 25 percent of the allowed
costs of non-applicable (generic) drugs and 95 percent of the negotiated price of
applicable (brand) drugs plus 25 percent of dispensing fees and vaccine administration,
if any, for applicable (brand) drugs between the decreased ICL and standard ICL.
Direct and Indirect Remuneration (DIR)

Part D sponsors must include all expected amounts that will be reported as DIR under “Rebate”
in the BPT. The DIR reported under “Rebate” represents the Part D sponsors’ best estimate of
all DIR categories and amounts that they expect to report under the Part D payment
reconciliation process for the respective contract year. The development of the DIR amounts
must be consistent with the development of projected costs.

CY2023 Part D BPT Instructions

PRICING CONSIDERATIONS
Definition of Direct and Indirect Remuneration

Per 42 CFR Section 423.308, direct and indirect remuneration (DIR) comprises any and
all rebates, subsidies, or other price concessions from any source (including
manufacturers, pharmacies, enrollees, or any other person or entity) that serve to
decrease the costs incurred by the Part D sponsor (whether directly or indirectly) for the
Part D drug. DIR includes discounts, charge-backs, average percentage rebates, cash
discounts, free goods contingent on a purchase agreement, up-front payments, coupons,
goods in kind, free or reduced-price services, grants, or other price concessions or
similar benefits. DIR does not include the manufacturer discount amounts received
under the Medicare CGDP.
DIR also includes price concessions from pharmaceutical manufacturers for purchases
under the Medicare prescription drug benefit that are received by subcontractors of
Part D sponsors, such as pharmacy benefit managers (PBM), even if the price
concessions are retained in lieu of higher service fees. CMS must assume that if a PBM
retains a portion of the manufacturer rebates that it negotiates on behalf of a Part D
sponsor, the direct payment that the PBM receives from the sponsor for its services will
be less, since the sponsor will have received a price concession from the PBM. This
price concession is a retained rebate and thus must be reported as DIR for payment
purposes.
In accordance with CMS guidance, Part D sponsors may enter into risk-sharing
arrangements with entities other than CMS by sharing risk around the cost of the drug
as reflected on claims data. Any gains or losses that the Part D sponsor may experience
as a result of these risk-sharing arrangements also constitute DIR that must be reported
to CMS. As with other types of DIR, the value can be negative.
Generic dispensing incentive payments, and any adjustments to generic dispensing
incentive payments made to pharmacies after the point-of-sale dispensing event, are
also considered DIR. Please note that generic dispensing incentive payments made to
the pharmacy at the point-of-sale are part of the dispensing fee reported on the PDE
record and therefore are not included in the DIR Report for Payment Reconciliation.
Enrollment

The projected enrollment for the Part D bid in an MA-PD plan must be consistent with that for
the corresponding MA bid and must reflect the same underlying population.
Gain/Loss Margin

Gain/loss margin refers to the additional revenue requirement beyond benefit expenses and
non-benefit expenses.
By statute, the bid must represent the revenue requirement of the expected population;
therefore, the gain/loss margin requirements must be met with the gain/loss margin entered in
the BPT.
Do not combine the gain/loss margins for the Medicare Advantage (MA) and Part D
components of MA-PD bids to satisfy these Instructions.
Do not combine the gain/loss margins for bids in segmented plans to satisfy these Instructions.

CY2023 Part D BPT Instructions

Page 14 of 86

PRICING CONSIDERATIONS

See the “Instructions for Completing the Medicare Advantage Bid Pricing Tool for Contract
Year 2023” for gain/loss margin requirements that are specific to MA bids.
The gain/loss margin entered in the BPT must be determined in consideration of other CMS
instructions such as Total Beneficiary Cost (TBC). If there is a conflict between satisfying
gain/loss margin requirements and other CMS instructions, flexibility will be given to the
gain/loss margin requirements only to the extent necessary to meet the other CMS instructions.
Such exceptions to the gain/loss margin requirements must be disclosed, be fully explained and
supported, and ultimately be approved by CMS.
Gain/loss margin requirements apply at two levels—the bid level and an aggregate level; both
sets of requirements must be met in the initial bid submission and upon bid resubmission or
withdrawal.
Definitions

In the BPT and these Instructions, the term—
•

•

•
•

“Plan Category” refers to the following groupings of Part D bids:
◦ Part D plans that are part of an MA-PD plan, that is, Part D BPTs that have a
corresponding MA BPT; and
◦ Part D plans that are not part of an MA-PD plan, that is, Part D BPTs with
the following Plan Type Codes: PDP, PACE, 1876 Cost, and 1833 Cost.
“Level of aggregation” refers to the level at which the gain/loss margin entered
in the BPTs must comply with the aggregate-level gain/loss margin
requirements.
◦ The Part D sponsor may choose one of the following two levels:
organization level (that is, the legal entity that contracts with CMS under one
or more contracts to provide Part D benefits) or parent organization level.
◦ The Part D sponsor must enter the chosen level of aggregation in the BPT.
◦ The level of aggregation selected in the Part D BPT must match the level
selected in the MA BPT of an MA-PD bid.
◦ The level of aggregation selected in the BPT must be the same for all general
enrollment plans & I/C SNPs and D-SNPs in the same Part D sponsor/
parent organization.
“Aggregate Part D gain/loss margin” refers to the projected enrollment-weighted
average BPT PMPM gain/loss margin for the applicable plan category.
“Non-Medicare business” refers to all health insurance business that is not
Medicare Advantage or Part D. Non-Medicare business includes, but is not
limited to: (i) Medigap (Medicare Supplement); (ii) Medicaid; (iii) MMPs
offered through a Financial Alignment Demonstration; (iv) Stop Loss;
(v) dental, vision, and commercial lines of business; and (vi) the non-Part D
portion of Section 1876 cost plans, Section 1833 cost plans, and PACE plans.
Non-Medicare business excludes administrative services only (ASO) business.
The “non-Medicare business” must be calculated consistently with what is
reported as net underwriting gain (loss) or net income (loss) in the financial
statements without adjustment. The related party guidance does not apply to the
calculation of non-Medicare gain/loss margin.

CY2023 Part D BPT Instructions

PRICING CONSIDERATIONS

•

•

“MA and Part D business” refers to all MA and Part D enrollees (including, but
not limited to: (i) enrollees in hospice or ESRD status; and (ii) enrollees in
SNPs, MSA plans, ESRD-SNPs, EGWPs, and the Part D portion of the
following: Section 1876 cost plans, Section 1833 cost plans, and PACE plans).
“Corporate gain/loss margin requirement” refers to the Part D sponsor’s
gain/loss margin requirement using either the non-Medicare corporate gain/loss
margin basis or the Risk-Capital-Surplus corporate gain/loss margin basis as
explained below.
◦ The “Non-Medicare” corporate gain/loss margin basis applies if the volume
of the Part D sponsor’s non-Medicare business, for which it has discretion in
rate setting, is greater than or equal to 10% of the Part D sponsor’s total
non-Medicare business.
◦ The “Risk-Capital-Surplus” corporate gain/loss margin basis applies if: (i)
the volume of the Part D sponsor’s non-Medicare business, for which it has
discretion in rate setting, is less than 10% of the Part D sponsor’s total
non-Medicare business; or (ii) the Part D sponsor has no non-Medicare
business.

Bid-Level Requirements

The gain/loss margin entered in the BPT is allocated to basic coverage and
supplemental coverage based on the distribution of total prescription drug costs between
these coverages.
There is flexibility in setting the gain/loss margin at the bid level provided that—
•
•
•

The bid offers benefit value in relation to the gain/loss margin level;
Anti-competitive practices are not used; and
All aggregate-level gain/loss margin requirements described below are met.

The bid-level requirements below do not apply to Part D BPTs that have a
corresponding MA BPT. The bid-level requirements below apply only to Part D BPTs
with the following Plan Type Codes: PDP, PACE, 1876 Cost, and 1833 Cost.
✓ Benefit Value

The bid must provide benefit value in relation to the gain/loss margin level.
For a bid with a high gain/loss margin, consideration must be given to—
•

Premium changes that can be made in CY2023 to reduce gain/loss margin.

✓ Anti-competitive Practices

Anti-competitive practices will not be accepted. For example, significantly low or
negative gain/loss margin for plans that have substantial enrollment and stable
experience, or “bait and switch” approaches to specific plan gain/loss margin
buildup, will be rejected, absent sufficient support that such pricing is consistent
with these Instructions.

CY2023 Part D BPT Instructions

Page 16 of 86

PRICING CONSIDERATIONS
Aggregate-Level Requirements

The aggregate-level requirements are applied separately to each plan category.
See the “MA-PD Gain/Loss Margin Requirements” section in this pricing consideration
for the requirements for Part D plans that are part of an MA-PD plan.
✓ Year-to-Year Consistency

Although actual gain/loss margin may vary from year to year, CMS expects
certifying actuaries to price bids such that actual Part D aggregate gain/loss margin
over the long term is consistent with (that is, follow) the gain/loss margin
assumptions used for pricing. That is, at the applicable level of aggregation,—
•
•

Actual aggregate Part D gain/loss margin is to be consistent with the aggregate
Part D gain/loss margin used in pricing, as a percentage of revenue.
A point estimate of actual corporate gain/loss margin is to be consistent with the
corporate gain/loss margin requirement used for the Part D pricing.

✓ Requirements for Part D Plans Without Corresponding MA Plans

This requirement applies only to Part D BPTs with the following Plan Type Codes:
PDP, PACE, 1876 Cost, and 1833 Cost.
For Part D sponsors, if the corporate gain/loss margin basis is—
•

•

“Non-Medicare,” then the aggregate Part D gain/loss margin as a percentage of
revenue must be within 1.5 percent of the Part D sponsor’s non-Medicare
business gain/loss margin requirement, unless CMS grants an exception, as
explained below.
◦ An exception for unique circumstances must be disclosed, be fully explained
and supported, and ultimately be approved by CMS.
◦ The exception applies only for CY2023.
“Risk-Capital-Surplus,” then the aggregate Part D gain/loss margin, as a
percentage of revenue, must be set by taking into account the degree of risk and
capital and surplus requirements of the Part D sponsor’s MA and Part D
business prior to any impact of sequestration.

✓ Minnesota Senior Health Options Program

For bids participating in the Minnesota Senior Health Options program, additional
aggregate-level gain/loss margin requirements can be found at
https://www.cms.gov/Medicare-Medicaid-Coordination/Medicare-and-MedicaidCoordination/Medicare-Medicaid-Coordination-Office/
FinancialAlignmentInitiative/Downloads/MNMOU.pdf.

PRICING CONSIDERATIONS
MA-PD Gain/Loss Margin Requirements

The MA-PD gain/loss margin requirements are separate from the aggregate-level
requirements above. There are two options for setting the Part D gain/loss margin of
MA-PD bids:
Option A: Set the gain/loss margins at the bid level. Specifically, an MA-PD sponsor

must—
•
•

Set the Part D gain/loss margin for a plan as a percentage of revenue within 1.5
percent of the gain/loss margin for the MA component of the same MA-PD bid,
and
Apply this method consistently for all MA-PD bids submitted by the Medicare
Advantage Organization.

Option B: Set the Part D gain/loss margins consistent with the level of aggregation

selected in the BPT. Specifically, at the applicable level of aggregation,—
•
•

The MA-PD sponsor must set the Part D gain/loss margins equal for all plans.
The Part D gain/loss margin as a percentage of revenue must be within 1.5
percent of the aggregate MA gain/loss margin for all MA-PD bids.

Exclusions

Non-insurance revenues pertaining to investments and fee-based activities designed to
influence state or federal legislation such as the cost of lobbying activities cannot be
reflected in the bid. See the announcement about lobbying activities released via an
HPMS memorandum dated October 16, 2009.
Health Care Reform

See Appendix F for information concerning the provisions of the Patient Protection and
Affordable Care Act as amended by the Health Care and Education Reconciliation Act of 2010,
known collectively as the Affordable Care Act.
Non-Benefit Expenses

Non-benefit expenses are all of the bid-specific administrative and other non-benefit costs
incurred in the operation of the Medicare Prescription Drug Plan. Therefore, any allocation of
non-benefit expenses to the Part D bid (whether performed at the bid level or a broader level)
must take into consideration differences between the Part D bid and other bids, and the impact
on non-benefit costs of the Part D bid.
The non-benefit expenses must be entered separately on the BPT for the following categories:
•

Sales & Marketing
 Examples include, but are not limited to the cost of—
▪ Marketing materials;
▪ Commissions;
▪ Enrollment packages;
▪ Identification cards; and
▪ Salaries of sales and marketing staff.

•

Direct Administration
 Examples include, but are not limited to—
▪ Customer service;
▪ Billing and enrollment;
▪ Claims administration;
▪ True out-of-pocket (TrOOP) administration;
▪ Pharmacy benefit management administration, which includes all of the costs
for performing call center, claims, formulary management, network
development and rebate management functions incurred by the plan or through a
subcontractor;
▪ Medicare CGDP administration;
▪ Medicare Part D user fees, which are $1.05 per-member per-year (pmpy) or
$.087 per-member-per-month (pmpm) on a national basis for CY2022. The
COB user fee will be collected at a monthly rate of $.1166 pmpm for the first
nine months of the coverage year;
▪ Part D National Medicare Education Campaign (NMEC) user fees. CMS
collects NMEC user fees based on a percentage of revenue; however, the BPT
entry is a pmpm equivalent value consistent with the calculation of other BPT
values. Part D sponsor may use the CMS estimate, which is $0.04 pmpm on a
national basis for CY2022, or develop an alternative estimate that is consistently
applied to all plans in the contract—for example, the Part D sponsor’s historical
amount relative to the CMS annual national estimate;
▪ Uncollected enrollee premium;
▪ Uncollected cost sharing, which includes plan liability resulting from cost
sharing not recovered in state-to-plan or plan-to-plan transactions;
▪ Medication therapy management programs;
▪ Disease management functions such as patient education and disease
monitoring; and
▪ Over-the-counter drugs.
Indirect Administration
 Examples include, but are not limited to, functions that may be considered
“corporate services,” such as—
▪ The position of CEO;
▪ Accounting operations;
▪ Actuarial services;
▪ Legal services; and
▪ Human resources.
Net Cost of Private Reinsurance (that is, reinsurance premium less projected
reinsurance recoveries)
Insurer Fees
 This category includes only the Health Insurance Providers Fee imposed by
Section 9010 of the Patient Protection and Affordable Care Act, as amended.

CY2023 Part D BPT Instructions

Page 19 of 86

PRICING CONSIDERATIONS

All non-benefit expenses must be reported using appropriate, generally accepted accounting
principles (GAAP). For example, acquisition expenses and capital expenditures must be
deferred and amortized according to the relevant GAAP standards (to the extent that is
consistent with the organization’s standard accounting practices, if not subject to GAAP). Also,
acquisition expenses (sales and marketing) must be deferred and amortized in a manner
consistent with the revenue stream anticipated on behalf of the newly enrolled members.
Guidance on GAAP standards is promulgated by the Financial Accounting Standards Board
(FASB). Of particular applicability is FASB’s Statement of Financial Accounting No. 60,
Accounting and Reporting by Insurance Enterprises.
Costs not pertaining to administrative activities must be excluded from non-benefit expenses.
Such costs include income taxes, changes in statutory surplus, investment expenses and the cost
of lobbying activities. See the Gain/Loss Margin section of Pricing Considerations for more
information.
Start-up costs that are not considered capital expenditures under GAAP are reported as follows:
•
•

Expenditures for tangible assets (for example, a new computer system) must be
capitalized and amortized according to relevant GAAP principles.
Expenditures for non-tangible assets (for example, salaries and benefits) must be
reported in a manner consistent with the organization’s internal accounting practices
and the reporting of similar expenditures in other lines of business.

Non-benefit expenses that are solely attributable to MA or Part D must be reported only on the
corresponding MA or Part D BPT.
Non-benefit expenses that are common to the MA and Part D components of MA-PD bids must
be allocated proportionately between the Medicare Advantage and Part D BPTs.
When Medicare benefits are funded by an outside source such as a state Medicaid program,
non-benefit expenses must be allocated proportionately between the Medicare revenue and the
other revenue source.
PBM Pricing

For CY2023, Part D sponsors must develop their Part D bids using the pass-through price or
negotiated amount paid to the dispensing provider at the point-of-sale as the basis for drug
costs. For Part D sponsors that are contracted with a PBM, the following provisions apply:
(i) when contracted under a lock-in pricing approach, the administrative expense component of
the bid must reflect the expected difference between the lock-in price, or amount negotiated
with the PBM, and the pass-through price (this difference is referred to as the risk premium or
PBM spread); and (ii) when the PBM retains a portion of the rebates, the administrative
expense component of the bid must include these costs.
Related-Party Arrangements

The related-party requirements apply to all Part D sponsors that enter into any type of
arrangement with or receive services from an entity with a different tax identification number
than that of the Part D sponsor, but is associated with the Part D sponsor by any form of
common, privately-held ownership, control or investment. This includes any arrangement
where the Part D sponsor does business with a related party through one or more unrelated

CY2023 Part D BPT Instructions

Page 20 of 86

PRICING CONSIDERATIONS

parties, such as a pharmacy or a pharmacy benefit manager. The requirements apply to all
related-party arrangements supporting the bid which are in effect during the base period and/or
contract year.
The related party pricing consideration does not apply to Part D sponsors’ arrangements with
parties within the Part D sponsors’ own tax identification number. When a Part D sponsor has
an arrangement for benefit services within their tax ID number, they may 1) submit PDE data
that matches the reporting of these internal transactions in their financial statements,
2) establish the pharmacy under a new tax identification number and follow the related party
instructions, or 3) follow the actual cost methods detailed in the CY2023 Part D BPT
instructions and submit additional documentation that explains and compares how these costs
are reflected in the bid versus the Part D sponsor’s financial statements.
The objective of the requirements for related-party arrangements is to ensure that financial
arrangements between the Part D sponsor and related parties (i) are not significantly different
from the financial arrangements that would have been achieved in the absence of the
relationship and (ii) do not provide the opportunity to over- or under- subsidize the bid.
CMS requires all Part D sponsors to disclose whether or not they are in a business arrangement
with a related party. Part D sponsors in a business arrangement with a related party must
disclose and support each and every related-party arrangement at the time of the initial bid
submission and prepare the bid and documentation in accord with the requirements in this
section and Appendix B for each identified related party.
A Part D sponsor in a related-party arrangement must—
•
•

•

Declare the related-party arrangement(s) to CMS at the time of the initial bid
submission.
Disclose all services that are covered in the arrangement(s). These include, but are not
limited to:
 Claims processing
 Network (retail and mail order pharmacy) access
 Clinical services, such as Utilization Management
 Formulary management
 Rebate contracting
 Drugs at related-party retail and/or mail order pharmacies
 Marketing materials and ID cards
 Call center operations
Select one of the following methods for entering costs associated with the related-party
arrangement into the BPT.
 Actual Cost Method for Administrative Services,
 Actual Cost Method for Benefit Costs,
 Market Comparison through Part D Sponsor, or
 Market Comparison through Related Party

Part D sponsors always have the option to use the Actual Cost Method in bid preparation.
Part D sponsors only have the option to use the Market Comparison through Part D Sponsor

CY2023 Part D BPT Instructions

Page 21 of 86

PRICING CONSIDERATIONS

Method when the Part D sponsor has a comparable arrangement with an unrelated party. Part D
sponsors only have the option to use the Market Comparison through Related Party Method
when the related party has a comparable arrangement with an unrelated party. For comparison
purposes, the unrelated party must be a Part D organization for benefit costs arrangements and
may be a Part D or non-Medicare organization for administrative services arrangements.
Comparable rate demonstrations must be based on actual contracts which must be available for
review by CMS upon request. When supporting comparable rates through the related party, the
Part D sponsor must include with the rate analysis a signed attestation from the related party
stating that the actual contracts will be available upon request for review by CMS. Note that, if
a related-party arrangement includes both administrative services and benefit services, the
requirements apply separately to the costs associated with such administrative and benefit
services.
Actual Cost Method for Administrative Services

A Part D sponsor using the actual cost method for administrative services must prepare
the BPT in a manner that does not recognize the independence of the related party.
Under this method, the BPT is prepared as follows:
•

•

The actual cost of the non-benefit services provided by the related party is
entered as the non-benefit expense of the Part D sponsor. The gain/loss margin
of the related party is excluded from the non-benefit expense of the Part D
sponsor.
When entering gain/loss margin in the BPT, the Part D sponsor may consider the
gain/loss margin of the related party, subject to the gain/loss margin
requirements.

Supporting documentation of the development of the actual cost method for
administrative services must be provided with the initial bid submission as required in
Appendix B.
Actual Cost Method for Benefit Costs

Under the actual cost method for benefit costs, the BPT is prepared as follows:
•
•
•

All fees paid to the related party for benefit costs are entered as the benefit
expense of the Part D sponsor.
The related-party benefit costs are consistent with the actual and projected PDE
experience of the plan.
The gain or loss of the related party with respect to the Part D benefit costs is
provided in the supporting documentation.

Supporting documentation of the development of the actual cost method for benefit
costs must be provided with the initial bid submission as required in Appendix B.
Market Comparison through Part D Sponsor Method

A Part D sponsor using the market comparison through Part D sponsor method must
prepare the BPT in a manner that recognizes the independence of the related party by
reporting all costs in the related-party arrangement to non-benefit expense for
administrative services arrangements and to benefit expenses for benefit costs

arrangements. To demonstrate that the arrangement with the related party is
comparable, the Part D sponsor must—
•
•
•

Provide an analysis that clearly explains how the financial results are not
significantly different from what is achieved in the absence of the related-party
relationship for the same services.
Show that results from the same utilization priced through the related and
unrelated party contracts are within plus or minus five percent.
Show that both contracts in the comparison are associated with sufficient costs
to be considered valid contracts.

Supporting documentation for the market comparison through Part D sponsor method
must be provided with the initial bid submission as required in Appendix B.
Market Comparison through Related Party Method

A Part D sponsor using the market comparison through related party method must
prepare the BPT in a manner that recognizes the independence of the related party by
reporting all costs in the related-party arrangement to non-benefit expense for
administrative services arrangements and to benefit expenses for benefit costs
arrangements. To demonstrate that the arrangement with the Part D sponsor is
comparable to arrangements with unrelated parties, the related party must—
•
•
•

Provide an analysis that clearly explains how the financial results are not
significantly different from what is achieved in the absence of the related-party
relationship for the same services.
Show that results from the same utilization priced through the related and
unrelated party contracts are within plus or minus five percent.
Show that both contracts in the comparison are associated with sufficient costs
to be considered valid contracts.

Supporting documentation for the market comparison through related party method
must be provided with the initial bid submission as required in Appendix B.
Risk Score Development for CY2023

The projected CY2023 risk score must—
•
•
•
•

Be based on the data sources and their respective weights, as specified in the resources
listed below in the Risk Adjustment Information Sources subsection.
Reflect the expected risk score trend at the bid level.
Be appropriate for the expected population.
Be adjusted for CY2023 normalization.
Risk Score Calculation Approaches

There are two methods for calculating the projected risk score: the preferred approach
and the alternate approach.
•

The preferred approach is to start with either the beneficiary or plan-level data
files provided by CMS, which contain the calculated risk scores using the

CY2023 Part D BPT Instructions

Page 23 of 86

PRICING CONSIDERATIONS

•

CY2023 payment model on 12 months of 2021 membership or the July 2021
enrollees, respectively.
The alternate approach allows new plans or plans with significant population
changes to use a different starting point for estimating their contract year risk
score.

For both approaches, explicit adjustments for the following factors are required:
•
•
•
•
•

Run out of diagnosis data from all sources, including differences in the final
cut-off date for data submission.
Bid-specific coding trend.
Changes in bid population.
Impact of any improvements to operational and submission process for
diagnosis data sources.
Other appropriate factors.

For an alternate approach, Part D sponsors must consider the following additional
adjustments:
•

•

•

•

•

•

Conversion to risk model-specific unblended risk scores.
◦ If the starting risk scores are blended scores, then Part D sponsors must
produce unblended risk scores before the conversion to raw risk scores.
Conversion to a raw risk score.
◦ When starting from a data source with normalized risk scores, such as the
MMR, Part D sponsors must consider a conversion to a raw (un-normalized)
scores before making other adjustments.
Impact of lagged versus non-lagged diagnosis data.
◦ If the starting risk scores are based on lagged diagnosis data, as is the case
for initial risk scores, Part D sponsors must transition the scores from lagged
to non-lagged risk scores.
Seasonality.
◦ If the starting risk score is based on membership that is other than the July
cohort or a full calendar-year cohort, then Part D sponsors must make an
adjustment for enrollment seasonality.
Risk model change.
◦ This includes the use of a different model in the data source versus the
projection year and differences in the diagnoses included in each model.
Impact of changes to diagnosis data sources and weights between the time
period of the data source and the contract year. Examples of the use of this
factor include adjustments for—
◦ The transition of starting risk scores based on MMR data from incomplete to
final diagnosis data.
◦ An estimate of the impact of the final risk score reconciliation.

Once projected to the contract year, the risk scores must reflect the CY2023 Part D
normalization factor. Note that if a raw (not normalized) risk score associated with a
different model calibration year is being normalized, the CY2023 Part D normalization
factor is not the appropriate normalization factor.

Sequestration

Pricing assumptions must consistently reflect the effect of sequestration.
Supporting Documentation

In addition to the BPT and actuarial certification, organizations must submit supporting
documentation for every bid. See Appendix B for a description of the supporting
documentation requirements, including content, quality and timing.
Types of Part D-Covered Drugs
Brand Drugs

Brand drugs consist of (i) single-source drugs with no generic equivalent that were
FDA-approved under an original new drug application (NDA) and (ii) innovator multisource drugs that were originally marketed under an original NDA and that now have
generic equivalents.
Preferred/Non-Preferred Brand Drugs

Brand drugs that are placed in the most favorable position on the formulary in
comparison to other similar brand drugs should be allocated to the preferred brand drug
category. Brand drugs that are positioned in a less favorable position on the formulary
should be allocated to the non-preferred brand category in the BPT.

CY2023 Part D BPT Instructions

Page 25 of 86

PRICING CONSIDERATIONS
Generic Drugs

Non-innovator multi-source drugs are generic drugs.
Specialty Drugs

Specialty drugs are reported separately only when a plan utilizes designated Specialty
tiering in the formulary and PBP in accord with CMS guidelines. The CMS guidelines
require that cost sharing associated with that tier be limited to 25 percent in the initial
coverage range when the plan has the standard deductible, which is $480 for CY2022.
When the plan has a decreased or no deductible, then an actuarially equivalent
coinsurance is permitted.
When designated Specialty tiering is used, all drugs classified as specialty-tier drugs on
the plan formulary must be reported by point-of-sale (retail or mail order as defined by
the PBP) in Worksheets 2, 6 and 6A of the BPT. The drugs in the Specialty tiers must
not be sorted by type of drug status and must not be reported as a component of the
generic, preferred brand and non-preferred brand drugs in the non-Specialty tiers.
When designated Specialty drug tiering is not used in the formulary and PBP, Specialty
drugs must be sorted by generic, preferred brand and non-preferred brand status and
must be reported in these categories by point-of-sale (retail or mail order as defined by
the PBP). In this situation, the Specialty categories in Worksheet 2, 6 and 6A are not
completed.

WORKSHEET 4

PD WORKSHEET 4 – RX STANDARD COVERAGE WITH
ACTUARIALLY EQUIVALENT COST SHARING
Worksheet 4 must be completed when the plan benefit type is actuarially equivalent. The
three tests that must be satisfied to demonstrate actuarial equivalence are as follows:
•
•
•

The average coinsurance percentage for amounts between the deductible and the
ICL must be actuarially equivalent to 25 percent; and
The average coinsurance percentage above the catastrophic limit must be
actuarially equivalent to the percentage for DS coverage.
The average coinsurance percentage for amounts between the ICL and
catastrophic limit must be actuarially equivalent to the percentage for
DS coverage.

CONSIDERATIONS FOR ACTUARIALLY EQUIVALENT COVERAGE
Although the average cost sharing between the deductible and ICL must be 25 percent for
an AE plan, it is expected that the cost sharing will be restructured to encourage more
efficient drug use through tiered copays and/or coinsurance. As compared to DS plans,
AE plans generally have higher generic, preferred brand and mail service utilization and
lower non-preferred brand utilization.
Part D sponsors must model the differences between the AE benefit and the DS by
making adjustments in utilization and average allowed amounts by type of drug and
point-of-sale (retail or mail order as defined by the PBP) in Worksheets 6 and 6A. The
distribution of utilization between generic and brand, and between retail and mail, must
be reasonable given the proposed benefit. Significant changes to the benefit are expected
to result in meaningful differences in utilization when compared to the DS bid.

WORKSHEET 5

PD WORKSHEET 5 – RX ALTERNATIVE COVERAGE
Worksheet 5 must be completed when the plan benefit type is basic alternative or
enhanced alternative. The six tests that must be satisfied to demonstrate actuarial
equivalence are as follows:
•
•
•
•
•
•

The value of total coverage is at least actuarially equivalent to DS coverage;
The alternative unsubsidized value of coverage is no less than the DS
unsubsidized value of coverage;
The average alternative benefits for beneficiaries with allowed drug costs at the
ICL are not less than the average DS benefits at the ICL;
The deductible is not greater than the DS deductible; and
The average alternative catastrophic cost sharing is not greater than the average
DS catastrophic cost sharing.
The average coinsurance percentage for amounts between the ICL and
catastrophic limit is at least actuarially equivalent to DS coverage.

CONSIDERATIONS FOR BASIC ALTERNATIVE AND ENHANCED ALTERNATIVE COVERAGE
Although the average cost sharing between the deductible and ICL must be 25 percent for
a BA and less than or equal to 25 percent for an EA plan, it is expected that the cost
sharing will be restructured to encourage more efficient drug use through tiered copays
and/or coinsurance. As compared to DS plans, BA and EA plans generally have higher
generic, preferred brand and mail service utilization and lower non-preferred brand
utilization.
Part D sponsors must model the differences between the BA or EA benefit and the DS by
making adjustments in utilization and average allowed amounts by type of drug and
point-of-sale (retail or mail order as defined by the PBP) in Worksheets 6 and 6A. The
distribution of utilization between generic and brand, and retail and mail, must be
reasonable given the proposed benefit. Significant changes to the benefit are expected to
result in meaningful differences in utilization when compared to the DS bid.
BA and EA plans may reduce the value of the deductible. BA and EA plans may provide
additional coverage in the gap. Since the value of coverage up to the ICL must remain the
same relative to the DS, a supplemental premium will result unless the cost of the
additional coverage is offset by savings in catastrophic coverage.
Additional coverage in the gap can delay the point at which a beneficiary reaches
catastrophic coverage. This delay can reduce the amount of reinsurance that will be
provided, cause induced utilization and increase the risk profile of the group. Members
with extremely high spending will not benefit as much as those with moderate amounts of
spending.

WORKSHEET 6

PD WORKSHEET 6 – SCRIPT PROJECTIONS FOR DEFINED
STANDARD, ACTUARIALLY EQUIVALENT OR ALTERNATIVE
COVERAGE
Worksheet 6 summarizes drug utilization and costs by type of drug and point-of-sale (retail or
mail order as defined by the PBP) in different distributions of drug spending. In addition,
Worksheet 6 illustrates the underlying assumptions used in the demonstration of the actuarial
equivalence tests in Worksheets 4 and 5. Section II collects data in a manner that supports an
actuarial comparison of the proposed AE, BA or EA plan benefit type to DS coverage.

CONSIDERATIONS
Although this worksheet is not a detailed model of the cost-sharing structure of the AE, BA or
EA plan design, the impact of tiered cost sharing, decreased ICL and benefit management
programs on utilization must be clearly demonstrated. The distribution of utilization between
generic and brand, and between retail and mail, must be reasonable given the proposed benefit.
Significant changes to the alternative benefit are expected to result in meaningful differences in
utilization when compared to the DS bid. Part D sponsors must model the impact of the
alternative benefit compared to the DS by making adjustments in utilization and average script
pricing in Worksheet 6. The distributions must be based on the intervals defined for DS
coverage. For purposes of modeling the alternative coverage, members must be reported in the
claims interval in which they were reported under DS coverage even though their total drug
spend may be different because of the impact of the alternative benefits. For example, lines 1
through 9 must reflect the utilization for the AE, BA or EA plan for members expected to have
less than the DS ICL of $4,430 in CY2022. In other words, the amounts summarized in
columns i, j and k must be based on the same members represented in columns f, g, and h of
each line.
Refer to the “Pricing Considerations” section of the Instructions for information on modeling
the impact of coverage in the gap, and decreased ICL.

SECTION I – GENERAL INFORMATION
This section displays the information entered on Worksheet 1, Section I.

SECTION II – PROJECTIONS FOR EQUIVALENCE TESTS
Data are collected for four levels of allowed costs on lines 1 through 36. The distribution of the
population and Part D covered drug claims reported on Worksheet 3 must be used in
completing this section. Columns f through h must be completed for all plans based on
DS coverage; columns i through k must be completed when the plan benefit type is AE, BA or
EA based on the alternative coverage. In developing the cost-sharing values in columns h and
k, do not model the impact of the deductible, coverage gap and LIS subsidy. To model
column h, use the cost-sharing structure of the DS plan; to model column k, use the costsharing structure of the alternative (AE, BA or EA) plan.

WORKSHEET 7
Lines 5 and 6 – Basic Part D Premium (prior to A/B Rebate Reallocation)

The values are calculated automatically in the BPT. Line 4 is calculated as line 1 minus line 2
plus line 3 minus line 4. Line 6 reflects the value of the basic Part D premium from line 5 after
the rounding rule selected on line 9 of this section has been applied. If the basic Part D
premium is negative and the plan benefit type is DS, AE or BA, then the Part D sponsor is
permitted to lower its estimate of the NAMBA and BBP. If the plan benefit type is EA, then the
Part D sponsor is permitted to lower its estimate of the NAMBA and BBP or fully offset the
negative basic premium with a supplemental Part D premium. The basic Part D premium,
before and after the rounding rule is applied, will be updated based on the actual national
average monthly bid amount and base beneficiary premium that are calculated and published
by CMS in early August.
Lines 7 and 8 – Supplemental Part D Premium (prior to A/B Rebate Reallocation)

The values are calculated automatically in the BPT when supplemental benefits are offered.
Line 6 is carried from Worksheet 5 of the BPT. Line 7 reflects the value of the supplemental
Part D premium from line 6 after the rounding rule selected on line 12 of this section has been
applied.
Line 9 – Prospective Federal Reinsurance (Non-Standardized)

The value is carried from other worksheets in the BPT based on the plan benefit type (DS, AE,
BA or EA).
Line 10 – Prospective Low-income Cost-Sharing Subsidy (Non-Standardized)

The value is carried from other worksheets in the BPT based on the plan benefit type (DS, AE,
BA or EA).
Line 11 – Target Adjustment (Allowed Costs as a Ratio of Bid)

The target adjustment is the allowed costs percentage of the bid and it is used in calculating the
target amount for risk corridor payments. The value is calculated as—
[(1.00 – administration cost percentage) X (total direct subsidy payments + total beneficiary
premiums related to the standardized bid amount)]
Line 12 – Prospective Brand Discount Amount

The value is carried from Worksheet 6A of the BPT.
Line 13 – Rounding Rule

Select the option from the drop-down box that corresponds to the preferred method for
rounding the Part D premium. The valid options are $0.10 and $0.50. MA-PD plans are
required to round to the nearest $0.10; Part D plans are permitted to round to either the nearest
$0.10 or nearest $0.50.

APPENDIX A

IV. APPENDICES
APPENDIX A – ACTUARIAL CERTIFICATION
GENERAL
CMS requires an actuarial certification to accompany every bid submitted to HPMS. If a
certification is not submitted via the HPMS certification module, the bid will not be considered
for CMS review and approval. Every Part D BPT requires a certification. Likewise, every
MA BPT requires a certification.
A qualified actuary who is a member of the American Academy of Actuaries (MAAA) must
complete the certification. The objective of obtaining an actuarial certification is to place
greater responsibility on the actuary’s professional judgment and to hold him/her accountable
for the reasonableness of the assumptions and projections.
Certification Module

The certification module contains the following features:
• Standardized required language.
• The ability to append free-form text language to the required standardized language.
• A summary of key information from the submitted bids.
• Links to additional information regarding the bid package, such as the PBP, BPT and
supporting documentation.
• The ability to certify multiple bids/contracts.
• The ability to print and save the submitted certification.
An initial actuarial certification must be submitted via the HPMS certification module in June.
The actuary must also certify the final bid (that is pending CMS approval) via the certification
module in August following the CMS publication of the Part D national average monthly bid
amount, the Part D base beneficiary premium, the Part D regional low-income premium
subsidy amounts and the MA regional benchmarks. Actuaries are not required to certify every
intermittent resubmission throughout the bid review process, but they may do so if they wish.
Note that in the event that the PBP changes after the “final” bid is certified, the bid that is
uploaded into HPMS with the revised PBP must be recertified whether or not the BPT changes.
Material changes to the certification language (after the initial June certification submission)
are not allowed without prior written permission from the CMS Office of the Actuary.
Multiple actuaries may be assigned to one contract to perform the certifications. For example, a
consulting actuary may certify the Part D portion of a bid, while an internal plan staff actuary
may certify the MA portion of the bid. Also, one actuary may certify plan Hxxxx-001, while a
different actuary may certify plan Hxxxx-002. The instructions contained in this appendix must
be followed by all certifying actuaries.
Additional information regarding the actuarial certification process (including technical
instructions for completing the HPMS certification module) will be included in an initial
actuarial certification deadline memorandum released via HPMS.

APPENDIX B

APPENDIX B – SUPPORTING DOCUMENTATION
GENERAL
In addition to the BPT and actuarial certification, Part D sponsors must provide CMS with
supporting documentation for every bid, as described in these Instructions.
Unless otherwise noted, Part D sponsors must upload to HPMS all required supporting
documentation at the time of the initial June bid submission. Additional supporting
documentation must be made available to CMS auditors and reviewers upon request, and for
CMS reviewers, within 48 hours of the request, as required by these Instructions. Part D
sponsors must upload supporting documentation consistent with the final certified bid.
Additional information not listed by number in this appendix may be requested by CMS
reviewers and auditors at any point during bid desk review or a CMS audit.
Supporting documentation requirements apply regardless of the source of the assumption,
whether it was developed by the actuary, the Part D sponsor or a third party. If the actuary
relied upon others for certain bid data and/or assumptions, those individuals are subject to the
same documentation requirements. The actuary must be prepared to produce all substantiation
pertaining to the bid, even if it was prepared by others or is based on reliance.
In preparing supporting documentation, the actuary must consider ASOP No. 41, Actuarial
Communications. In accordance with Section 3.2, “Actuarial Report,” the materials provided
must be written “with sufficient clarity that another actuary qualified in the same practice area
could make an objective appraisal of the reasonableness of the actuary’s work.”
All data submitted as part of the bid process are subject to review and audit by CMS or by any
person or organization that CMS designates. Certifying actuaries and additional Part D BPT
actuarial contacts must be available to respond to inquiries from CMS reviewers regarding the
submitted bids.
Supporting documentation must—
•
•
•
•
•
•
•

•

Be clearly labeled and easily understood by CMS reviewers.
Explain the rationale for the assumptions, including quantitative support and details,
rather than just narrative descriptions of assumptions.
Describe bid-specific variations in addition to the overall pricing assumption or
methodology.
Match the values entered in the current BPT and tie to the PBP.
Include Excel spreadsheets with working formulas, rather than pdf files, and a narrative
explanation of the inputs and the calculations and their components.
Clearly identify if it is related to MA, Part D or both.
Clearly identify the bid(s) relating to the support. At a minimum, the contract number
and organization name must appear on the first page. Specific plan numbers must be
included where appropriate, such as on the first page, in a separate chart or as an
attachment.
Include a hard-coded date.

CY2023 Part D BPT Instructions

Page 66 of 86

APPENDIX B

•

Include the contract-plan ID (or organization name) and brief description in the
beginning of the file name.

Acceptable forms of supporting documentation include, but are not limited to, the following
items:
•
•
•
•
•

Meeting minutes that include comprehensive documentation of discussions related to
bid development.
A complete description of data sources–for example, a report’s official name/title, file
name, date obtained, source file, the precise name of any published tables used, etc.
Intermediate calculations showing each step taken to calculate an assumption.
A summary of contractual terms of administrative services arrangements.
A business plan.

Supporting documentation that is not acceptable or that may result in a request for additional
information includes, but is not limited to, the following items:
•
•

•
•
•

•
•
•

Materials that are accessible only through a secure server link that requires a password.
A reference to the supporting documentation for another plan, such as “the same as for
plan Hxxxx-xxx,” and not the documentation itself. The supporting documentation for a
bid must be self-contained.
Excel spreadsheets with a vague explanation or no explanation of the bid-specific inputs
and calculations.
PDF files with the “copy” function disabled.
A statement that the source of a pricing assumption is “professional judgment” with no
additional explanation of the data points underlying the assumptions–for example,
supporting factors, studies or public information.
“Living worksheets” that are overwritten with current data. Supporting documentation
must include the version of the worksheet that was used in bid preparation.
Information obtained after the bids are submitted.
A statement that a pricing assumption or methodology is assumed acceptable based on
its inclusion in a bid that was approved by CMS in a prior contract year. Data,
assumptions, methodologies and projections must be determined to be reasonable and
appropriate for the current bid, independent of bid filings in previous years.

SUBMITTING SUPPORTING DOCUMENTATION
Supporting materials must be in electronic format (for example, Microsoft Excel,
Microsoft Word, or Adobe Acrobat) and must be uploaded to HPMS. CMS will not accept
paper copies of supporting documentation. Note that multiple substantiation files can be
submitted to HPMS at one time by using “zip” files, which compress multiple files into one
(.zip file extension).
Also note that although one file can be uploaded to multiple plans in HPMS, documentation
must not be uploaded to plans to which it does not pertain. Similarly, it is not acceptable to
upload to multiple plans materials specific to a Part D plan, an MA bid or another contract
number.

CY2023 Part D BPT Instructions

Page 67 of 86

APPENDIX B

More requirements about the upload of substantiation files are located in HPMS in the “Notes”
section, under HPMS Home > (Plan Bids) Bid Submission > CY2023 > (Upload)
Substantiation > Next.
Cover Sheet

To expedite the bid review process, Part D sponsors must upload a “cover sheet” that lists all of
the supporting documentation that is uploaded or provided with the bid form. The filename
must include the phrase “cover sheet.” A cover sheet is required for each upload of
substantiation.
The cover sheet must include detailed information for each support item—such as the filename
and the location within the file, if applicable—and must clearly identify the bids for which such
support item applies and whether the substantiation is related to MA, Part D, or both.
Note that some documentation requirements apply to every bid (for example, every bid
contains a risk score assumption), while other documentation requirements apply only to bids
that contain certain assumptions (for example, manual rate documentation applies only if a
bid’s projection is based on manual rates). For documentation categories that apply to a subset
of bids that contain a specified assumption, the cover sheet must not refer to a “range” of
contract number-plan IDs (such as “plans 001 – 030” or “all plans under contract Hxxxx”). For
these items, the cover sheet must contain the exact contract number-plan IDs (contract/plan) to
which the documentation applies.
For subsequent substantiation uploads, the cover sheet must summarize the additional
documents uploaded at that time (that is, the cover sheet must not be maintained as a
cumulative list). The subsequent cover sheets must also contain the exact contract numberplan IDs rather than a “range” of contract number-plan IDs.
Sample check lists and cover sheets for the initial June bid submission, and for subsequent
substantiation uploads, are provided at the end of this appendix.
Timing

Part D sponsors and certifying actuaries must prepare all supporting documentation at the time
of the initial June bid submission so that it is immediately available to CMS and reviewers at
initial bid submission or readily available upon request as explained below.
•

•

•

The “Initial June Bid Submission” section of Appendix B describes supporting
documentation materials that Part D sponsors must upload to HPMS with the initial
June bid submission.
The “Upon Request by CMS Reviewers” section of Appendix B describes materials that
Part D sponsors and certifying actuaries must provide within 48 hours of request by
CMS reviewers and upload to HPMS prior to the final actuarial certification.
When a BPT is resubmitted, the Part D sponsor must upload a summary of changes,
including the cause and effect of each revision, authorized by CMS or CMS reviewers.
If multiple BPTs are resubmitted at the same time, the supporting documentation must
include a mapping of specific bid changes and contract number-plan IDs.
 Sample BPTs are not to be uploaded to HPMS.

APPENDIX B

•

Prior to the final actuarial certification—
 Part D sponsors and certifying actuaries must revise supporting documentation
consistent with the final certified bid. This includes additional information or
materials provided during bid review to support the bid.

elements include—
10.3.1. A list of all bids involved in approved cross-walks for CY2022 and proposed
cross-walks for CY2023 considered for base period data aggregation.
10.3.2. A statement of the intention to submit a cross-walk exception for CY2023, if
applicable.
10.4. Detailed qualitative and quantitative support for the development of the rebates and
all other types of direct and indirect remuneration (DIR) (Worksheets 1 and 3).
11. Detailed qualitative and quantitative support of the development of each trend projection
factor (Worksheet 2). The required elements include—

APPENDIX C – EMPLOYER/UNION-ONLY GROUP (EGWP)
REQUIREMENTS
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) gives
employers and unions a number of options for providing prescription drug coverage to their
retirees. Employers and unions can–
•
•
•

Provide coverage at least as good as Medicare’s Part D DS benefit and receive a retiree
subsidy of 28 percent of a retiree’s drug costs between $480 and $9,850;
Purchase customized benefits from a PDP or MA-PD pursuant to CMS waivers; or
Contract directly with CMS to become a PDP and provide customized benefits pursuant
to CMS waivers.

Under sections 1860D-22(b) and 1857(i) of the Social Security Act (SSA), CMS may waive or
modify Part D requirements that hinder the design of, offering of, or enrollment in an employer
or union Part D retiree plan. The waiver authority applies to PDPs and MA-PDs that offer
employer/union-only group plans and to employer/union-only groups that contract directly with
CMS to become a PDP.
For CY2006, CMS issued guidance that waives or modifies many of the requirements for these
entities. All of the standard Part D bidding guidelines apply, with the exception of those
specifically waived.
For CY2023, CMS does not require a Part D BPT for employer/union-only group plans.

CY2023 Part D BPT Instructions

APPENDIX D

APPENDIX D – CALCULATION OF NATIONAL AVERAGE MONTHLY
BID AMOUNT
For CY2006, the national average monthly bid amount was calculated using equal weighting
applied to all PDP sponsors, and MA-PD plans were assigned a weight based upon prior
enrollment. New MA-PD plans were assigned a zero weight. This approach was used because
no PDP enrollment data existed for 2005.
For CY2007 and CY2008, the national average monthly bid calculation was performed
according to the guidelines established by the “Medicare Demonstration to Limit Annual
Changes in Part D Premiums due to Beneficiary Choice of Low-Cost Plans.” Specifically,
80 percent of the calculation for CY2007 was based on the 2006 averaging methodology, also
known as the uniform-weighting average, and 20 percent was based on an enrollment-weighted
average. For CY2008, 40 percent of the calculation was based on the uniform-weighting
average and 60 percent was based on an enrollment-weighted average. The demonstration was
no longer in effect for CY2009 and the benchmarks were based on the 2008 enrollments
applied to the 2009 bids. The CY2022 benchmarks will be based on the 2021 enrollments
applied to the 2022 bids.
The following table illustrates the impact of the weighted enrollment methodology for
two enrollment periods, June 2020 and February 2021. Recall that the 2021 benchmark was
calculated as 100 percent of the enrollment-weighted approach.
The same values are presented based on the February 2021 enrollment. Since the
2022 benchmarks will be based on 2021 enrollment, these values may be useful for estimating
the 2022 benchmarks. The left section of the table shows the actual 2021 benchmarks, which
were calculated based on June 2020 enrollment. The right section, titled “February 2021
Enrollment,” indicates how the 2021 benchmarks would have been calculated based on more
current enrollment data.

This illustrative recalculation of the 2021 benchmarks is provided for the purpose of assisting
Part D sponsors in developing the projected 2022 national average monthly bid amount and

The final 2022 benchmarks will be based on the 2021 enrollments applied to the 2022 bids.

APPENDIX E

APPENDIX E – CALCULATION OF LOW-INCOME BENCHMARK
PREMIUM AMOUNTS
The Medicare Prescription Drug, Improvement, and Modernization Act of 2003 (MMA) directs
CMS to use a weighted average to calculate the regional low-income benchmark premium
amounts used in the determination of the low-income premium subsidy amounts. In
determining the 2006 low-income benchmark premium amounts, PDPs were weighted equally,
MA-PDs were assigned a weight based on prior enrollment as of March 31, 2005, and new
MA-PDs were assigned a zero weight. For CY2007, under the “Medicare Demonstration to
Transition Enrollment of Low-Income Subsidy Beneficiaries,” CMS calculated the regional
low-income benchmark premium amounts using the same weighting methodology applied in
2006.
For CY2008, CMS implemented a transition to the statutorily required weighting such that the
regional low-income benchmark premiums would experience a smaller decrease. CMS
calculated the 2008 regional benchmarks using a composite of the 2006 weighting approach
(simple average) and the statutory weighting formula (weighted average), as described below:
•

•

The first component, the simple average, was the same as the 2006 weighting
methodology for the regional low-income benchmark premium amount. The PDP
organization premium amounts for basic prescription drug coverage in each region were
weighted equally and the MA-PD plan premiums, after the application of Part A/B
rebates, were weighted based upon prior enrollment.
The second component was a weighted average of the premium amounts for each PDP
and MA-PD with a weighting based on each plan’s prior enrollment as a percentage of
all beneficiaries enrolled in those plans.

For CY2008, the regional low-income benchmark amount was based on 50 percent of the first
component and 50 percent on the second component, as described above.
For CY2009, the “Medicare Demonstration to Transition Enrollment of Low-Income Subsidy
Beneficiaries” and the de minimis policy were not in effect. The regional low-income
benchmark amounts were calculated based on 100 percent of the weighted LIS enrollments.
For CY2010, the “Medicare Demonstration to Revise Part D Low-Income Benchmark
Calculation” established that the regional low-income benchmark amounts, based on
100 percent of the weighted LIS enrollments, would be calculated using the Part D premiums
for MA-PD plans before they were reduced by any applicable MA A/B rebates.
For CY2011 and subsequent years, in accord with the codification of the “Medicare
Demonstration to Revise Part D Low-Income Benchmark Calculation”, the weighted average
premium amounts will be calculated using the Part D premiums for MA-PD plans before they
have been reduced by any applicable Part A/B rebates.
The following table illustrates the impact of calculating the regional low-income benchmark
amounts based on 100 percent of the weighted LIS enrollments for two enrollment periods,
June 2020 and February 2021.

APPENDIX F

APPENDIX F – HEALTH CARE REFORM
PROVISIONS
The following provisions of the Patient Protection and Affordable Care Act as amended by the
Health Care and Education Reconciliation Act of 2010 apply to Part D bids for CY2022.
Coverage in the Gap

In CY2022, beneficiary cost sharing is 25 percent for non-applicable (generic) drugs; the
Part D sponsor’s liability for DS coverage is 75 percent. Beneficiary cost sharing remains
25 percent of the negotiated price for applicable (brand) drugs, defined for purposes of the
coverage gap discount program as the gross drug cost minus the dispensing fee and vaccine
administration fee, if any, under 1860D-14A(g)(6) of the SSA, and 25 percent of the dispensing
fee and vaccine administration fee, if any. Pharmaceutical manufacturers will provide a
70 percent discount off of the Part D sponsor’s negotiated price of the brand-name drug at the
point-of-sale. Ninety-five percent of the negotiated price of the drug and 25 percent of the
dispensing fee and vaccine administration fee, if any, will count toward the beneficiary’s
TrOOP; the Part D sponsor’s liability is 5 percent plus 75 percent of the dispensing fee and
vaccine administration, if any. Applicable drugs are defined in Section 1860D-14A(g)(2) of the
statute and are covered Part D drugs that are either approved under a new drug application
(NDA) under Section 505(b) of the Federal Food, Drug, and Cosmetic Act or, in the case of a
biologic product, licensed under Section 351 of the Public Health Service Act (other than a
product licensed under subsection (k) of such section 351) using a biologics license application
(BLA). Non-applicable drugs are covered Part D drugs that do not meet the definition of an
applicable drug.
These coverages apply to beneficiaries who, on the date of dispensing a covered Part D drug,
are enrolled in an MA-PD or PDP plan, are not enrolled in a qualified retiree prescription drug
plan, are not entitled to the low-income subsidy, have reached or exceeded the ICL and have
not exceeded the TrOOP threshold.
Low-Income Premium Subsidy Amounts

The approach to determine the low-income premium subsidy amounts that was established in
the “Medicare Demonstration to Revise Part D Low-Income Benchmark Calculation” and
approved on August 11, 2009 was codified. Therefore, the weighted average premium amounts
will be calculated for MA-PD plans using the Part D premiums before they have been reduced
by any applicable MA A/B rebates.
Income-Related Part D Premium

Similar to Medicare Part B, an income-related premium is established for Part D beneficiaries
with modified gross income greater than specified income thresholds. The income thresholds
for CY2021 are $88,000 per individual and $176,000 per couple. The CY2022 income
thresholds will be indexed to the August 2021 CPI, which will be released in September 2021.
The Part D income-related monthly adjustment amounts will be collected by the federal
government and will have no impact on the direct subsidy payments received by Part D
sponsors.

APPENDIX G

APPENDIX G – TRENDING RISK SCORES
This appendix includes the following considerations for developing trends for coding and
population changes to project CY2023 risk scores.
•
•
•
•
•
•

•

•

•

•

Include the most recent annual consecutive calendar risk scores that are available.
Use raw risk scores that are not normalized.
Reflect the same amount of paid claims run-out for each year’s risk scores.
Use final risk scores from each year or apply a completion factor to the last set of scores
to approximate a final score.
Use the same cohort for each year (for example, the July cohort).
Use the same model to estimate all payment year scores. If possible, use the risk
adjustment model for the upcoming payment year or apply a conversion factor to each
payment year’s risk scores to convert to a single risk model.
 The model conversion factor should be bid-specific. It can be generated from the
risk scores that CMS sends to Part D sponsors to support bidding; however, Part D
sponsors should also consider whether other years in their trends have a different
conversion factor (for example, when the population mix differs).
 The conversion factor can be derived by calculating risk scores from a year under
two different models. The factor can be a ratio of the scores under each model.
Part D sponsors should note that when converting risk scores from one model to
another, a conversion between denominator years is, more than likely, occurring also.
The risk scores in the conversion factor should be raw if the factor will be applied to an
old model raw risk score, which is then projected to the payment year.
Note: If Part D sponsors compare scores within a single cohort, and the risk adjustment
models do not have the same denominator year, the raw risk scores should be
normalized to the same year. Otherwise, some portion of the ratio between the models
will be attributed to the more recent denominator, rather than a difference in predicted
risk.
Divide cohorts into meaningful subgroups using the same considerations used to
determine allowed costs and project enrollment in each subgroup to the payment year.
 Weight subgroup risk scores by enrollment in each subgroup per year to determine
annual risk scores for trending.
Compare year over year risk scores to obtain a trend factor. Unless the Part D sponsor is
anticipating changes in coding efforts or population characteristics, more than two years
of risk scores will help minimize the effect of random changes in coding patterns and
enrolled population. If deviations from previous trend are expected in the payment year,
provide justification for such changes in the supporting documentation.
 If starting with base year risk scores that are blended, Plan sponsors are to assess
whether there are bid-specific risk score trends unique to each model and adjust
their overall trend accordingly.
 Use this trend factor to project from base period risk scores to payment (contract)
year raw risk scores.
