New 2025 Prescription Drug Event (PDE) File Layouts (FINAL)

The purpose of this memo is to share the new 2025 Prescription Drug Event (PDE) Final File
Layouts, “PDE Inbound File Layout Final_20250101.xlsx” and “PDE Outbound File Layout
Final_20250101.xlsx,” which will become effective on January 1, 2025. On May 31, 2022, CMS
released a memo, “Proposed Updates to the Prescription Drug Event (PDE) File Layout; Seeking
Feedback,” 1 requesting Part D sponsor feedback on the Centers for Medicare & Medicaid
Services’ (CMS’) anticipated updates to the PDE expanded file size and layouts. On November 1,
2022, CMS released a second memo, “New 2025 Prescription Drug Event (PDE) File Layouts
(draft); Seeking Feedback,” 2 requesting Part D sponsor feedback on the anticipated updates to the
PDE Inbound and Outbound Draft File Layouts. CMS carefully considered the feedback received
on the addition of new fields, changes to existing fields, file format, and timing of implementation
of the new file layouts, and is now sharing the finalized 2025 PDE File Layouts.
Timing
Until January 1, 2025, Part D sponsors should continue to use the current PDE Inbound File
Layout published on the Customer Service and Support Center (CSSC) Operations website to
submit their PDEs. Beginning January 1, 2025, Part D sponsors must use the new 2025 PDE
Inbound File Layout to submit PDE records (PDEs) for all Benefit Years and all Dates of
Service (DOS), including Benefit Years prior to 2025 and DOS prior to January 1, 2025. The
existing PDE Inbound File Layout will be accepted until the implementation date of the 2025
PDE Inbound File Layout on January 1, 2025, at which time the Prescription Drug Front-End
System (PDFS) will reject PDE submission files, regardless of the PDE’s Benefit Year,
submitted in the existing (“old”) format.
All Part D sponsors will be required to submit certification (CERT) test files prior to submitting
May 31, 2022 HPMS memorandum, Proposed Updates to the Prescription Drug Event (PDE) File Layout; Seeking
Feedback, available here.

production PDE files on January 1, 2025. CERT Testing is planned to begin on July 1, 2024.
CMS will provide CERT Testing requirements in advance.
CMS will also publish specific operational PDE reporting guidance and information on related
updated edits at a later date. Please note that CMS will issue separate guidance regarding the
operational implementation of the Inflation Reduction Act (IRA), 3 which may include additional
PDE File Layout updates.
Background
The expansion of the PDE file is the first increase in file length since the PDE file structure was
implemented in 2006. Currently less than 5% of the file length is available on the PDE File
Layouts to add new fields and/or to expand existing fields. As we look ahead to the future, CMS
is expanding the PDE File Layouts from their current 512-byte length to 1000 bytes, effective
January 1, 2025.
This expansion is being implemented to accommodate future business needs including, but not
limited to anticipated updates to the National Council for Prescription Drug Programs (NCPDP)
Telecommunication Standard, as well as to operationally implement Federal legislation. In
addition, the lengths of some of the existing fields on the PDE File Layouts are increasing,
requiring an overall reorganization of the fields within the PDE File Layouts.
Part D sponsors will notice the reorganization of fields into logical groupings in the attached final
2025 PDE File Layouts, including the addition of Filler within each grouping to allow for future
field expansions and/or additions. Filler is also added at the end of the PDE file record to
accommodate the addition of future new unrelated fields.
CMS thanks Part D sponsors for their feedback to the prior requests regarding CMS’ anticipated
updates to the PDE file size and file layouts; CMS has incorporated stakeholders’ suggestions into
the final PDE File Layouts, as applicable.
New Fields
As part of CMS’ effort to assist Medicare Part D sponsors in submitting complete and accurate
data for payment, to be compliant with Federal legislation and CMS regulations, and based on the
feedback received from stakeholders, CMS is adding the following new fields to the 2025 PDE
File Layouts:
1) Originally Prescribed Quantity
CMS is adding a new 10-position field, “Originally Prescribed Quantity,” to enable more accurate
identification of incrementally filled Schedule II products and to monitor for compliance. Editing
will be applied to ensure that the “Quantity Dispensed” does not exceed the “Originally Prescribed
Quantity.”
3

INFLATION REDUCTION ACT OF 2022, PL 117-169, August 16, 2022, available here.

2

Beginning January 1, 2025, Part D sponsors must report the “Originally Prescribed Quantity” for
Schedule II drugs that are reported on standard, electronically-submitted PDEs.
The new “Originally Prescribed Quantity” field will have a format of 9(7)V999. For PDEs with a
DOS prior to January 1, 2025, or for non-Schedule II PDEs, the value reported must be zero.
2) Pharmacy Price Concessions at POS
In light of the changes to the treatment of pharmacy price concessions, codified in the CY 2023
Medicare Advantage and Part D Final Rule (CMS-4192-F) 4 (hereinafter referred to as the
“pharmacy price concessions final rule”), CMS is adding a new dollar amount field, “Pharmacy
Price Concessions at POS.”
Beginning January 1, 2025, Part D sponsors must report in this field the maximum amount of any
contingent payments or adjustments that the Part D sponsor might receive from a network
pharmacy that would serve to decrease the total amount that the Part D sponsor pays for the drug,
i.e., all pharmacy price concessions. All other estimated remuneration applied at the point of sale
(POS) must be reported in the existing “Estimated Remuneration at POS Amount (ERPOSA)” field,
as described in #8 below.
The new “Pharmacy Price Concessions at POS” field will have a format of S9(9)V99, consistent
with the expanded dollar amount fields, as described in #10 below. Beginning January 1, 2025,
Part D sponsors must report pharmacy price concessions at the POS in this field, which must be a
positive dollar value (the value may never be negative), or may be $0 when there is no price
concession applied at the POS. For PDEs with a DOS prior to January 1, 2025, the value reported
must be zero.
3) Submission Type Code 1-5
CMS is adding 5 new “Submission Type Code” fields that will allow Part D sponsors to report up
to 5 instances of codes that identify specific types of claims on the PDE record, to align with
future versions of the NCPDP Telecommunication Standard. Note: If an updated NCPDP
Telecommunication Standard has not yet become effective as of January 1, 2025, that includes the
“Submission Type Code” field, the values of these fields on the PDE are optional and may be
spaces until the effective date of the new NCPDP Telecommunication Standard.
The 5 new PDE fields will have a format of X(2). Valid values that CMS will accept are included
in the PDE File Layouts’ Definition/Values column.
4) LTPAC Dispense Frequency
CMS is adding a new “LTPAC Dispense Frequency” field that will be used to identify long-term
and post-acute care short-cycle (LTPAC) dispensing PDEs. Currently, LTPAC dispensing is
reported in the existing “Submission Clarification Code” field on the PDE. Beginning January 1,
2025, this information will be reported via the “LTPAC Dispense Frequency” field, to align with
future versions of the NCPDP Telecommunication Standard. Note: If an updated NCPDP
Telecommunication Standard has not yet become effective as of January 1, 2025, that includes the
4

87 FR 27704, 27833 (May 9, 2022), available here.

3

“LTPAC Dispense Frequency” field, the value of this field on the PDE is optional and may be
spaces until the effective date of the new NCPDP Telecommunication Standard. The short-cycle
dispensing codes may continue to be reported in the “Submission Clarification Code” fields on the
PDE until the new NCPDP Telecommunication Standard becomes effective.
The new PDE field will have a format of X(2). Valid values that CMS will accept are included in
the PDE File Layouts’ Definition/Values column.
5) Inflation Reduction Act Fields
To operationally implement the applicable provisions of the IRA, CMS is adding new IRArelated fields to the PDE File Layouts. Please note that CMS will publish specific operational
PDE reporting guidance and information on related updated edits regarding the following new
PDE fields at a later date.
PDE Inbound Layout
a) Government Pay Subsidy
CMS is adding a new dollar amount field, “Government Pay Subsidy”. Beginning
January 1, 2025, Part D sponsors must report the government pay selected drug
subsidy amount in this field.
This new field will have a format of S9(9)V99, consistent with the expanded dollar
amount fields, as described in #10 below. This field must be a positive dollar value
(the value may never be negative), or may be $0 when there is no government pay
selected drug subsidy to report. For PDEs with a DOS prior to January 1, 2025, the
value reported must be zero.
b) Reported Manufacturer Discount
CMS is adding a new dollar amount field, “Reported Manufacturer Discount”.
Beginning January 1, 2025, Part D sponsors must report the amount that the plan
sponsor advanced at the point of sale for the Manufacturer Discount for applicable
drugs.
This new field will have a format of S9(9)V99, consistent with the expanded dollar
amount fields, as described in #10 below. This field must be a positive dollar value
(the value may never be negative), or may be $0 when there is no Manufacturer
Discount to report. For PDEs with a DOS prior to January 1, 2025, the value reported
must be zero. This amount will not increment the True Out-of-Pocket Accumulator
amount.
c) Deductible Accumulator
CMS is adding a new dollar amount field, “Deductible Accumulator”. Beginning
January 1, 2025, Part D sponsors must report the sum of the beneficiary's deductible
amount for the benefit year that is known immediately prior to adjudicating the claim.

4

This new field will have a format of S9(9)V99, consistent with the expanded dollar
amount fields, as described in #10 below. This field must be a positive dollar value
(the value may never be negative), or may be $0 when there is no cumulative
deductible to report. For PDEs with a DOS prior to January 1, 2025, the value
reported must be zero.
PDE Outbound Layout
Please note that all of the new IRA-related fields added to the PDE Inbound Layout will also be
added to the PDE Outbound Layout, with the following additions:
d) CMS Calculated Manufacturer Discount
CMS is adding a new dollar amount field, “CMS Calculated Manufacturer Discount”.
Beginning January 1, 2025, this field will contain the Manufacturer Discount amount
calculated by CMS during on-line PDE editing based on data reported by the Part D
sponsor on the PDE.
This new field will have a format of S9(9)V99, consistent with the expanded dollar
amount fields, as described in #10 below. For PDEs with a DOS prior to January 1,
2025, the value reported will be zero
e) Applicable Discount Percentage for Specified Small Manufacturer Drugs
CMS is adding a new field, “Applicable Discount Percentage for Specified Small
Manufacturer Drugs”. Beginning January 1, 2025, this field will contain the phasedin Manufacturer Discount percentage that applies for the benefit year of the PDE for
specified small manufacturer drugs, as provided by the statute.
This new field will have a format of X(2). For PDEs with a DOS provided by the
statute prior to January 1, 2025, the value reported will be spaces.
f) Applicable Discount Percentage for Specified Manufacturer Drugs Dispensed to
LIS Beneficiaries
CMS is adding a new field, “Applicable Discount Percentage for Specified
Manufacturer Drugs Dispensed to LIS Beneficiaries”. Beginning January 1, 2025,
this field will contain the phased-in Manufacturer Discount percentage that applies
for the benefit year of the PDE for specified manufacturer drugs dispensed to Low
Income Subsidy (LIS) eligible beneficiaries, as provided by the statute.
This new field will have a format of X(2). For PDEs with a DOS prior to January 1,
2025, the value reported will be spaces.
Updates to Existing Fields
In addition, CMS will make updates to the following existing fields on the 2025 PDE File
Layouts:
6) Product Service ID
CMS is expanding the existing “Product Service ID” field from its current 19-character length to
5

40 characters; i.e., from a format of X(19) to the new format of X(40), consistent with future
versions of the NCPDP Telecommunication Standard. This change will become effective on
January 1, 2025. Direction on how to populate this field is included in the PDE File Layouts’
Definition/Values column.
7) Prescriber ID
CMS is expanding the existing “Prescriber ID” field from its current 15-character length to 35
characters; i.e., from a format of X(15) to the new format of X(35), consistent with future versions
of the NCPDP Telecommunication Standard. This change will become effective on January 1,
2025. Direction on how to populate this field is included in the PDE File Layouts’
Definition/Values column.
8) Estimated Remuneration at POS Amount (ERPOSA)
CMS is changing the name of the existing “Estimated Rebate at POS” field to “Estimated
Remuneration at POS Amount (ERPOSA).” This field name change will be implemented prior to
the January 1, 2024 applicability date of the pharmacy price concessions final rule. Until January
1, 2025, the ERPOSA field (under its current name or under its new name) must include all
remuneration applied at the POS, including any pharmacy price concessions applied at the POS.
For detailed PDE reporting instructions, please see the October 14, 2022 HPMS memorandum
entitled, “Reporting Estimated Remuneration Applied to the Point-of-Sale Price." 5
For PDEs with a Date of Service (DOS) before January 1, 2024, this field must contain the
estimated amount of rebates and/or other price concessions that the plan sponsor is required to
apply, or has elected to apply, to the negotiated price as a reduction in the drug price made
available to the beneficiary at the POS.
For PDEs with a DOS between January 1, 2024 and December 31, 2024, this estimate must
reflect the maximum amount of any contingent payments or adjustments that the plan sponsor
might receive from a network pharmacy that would serve to decrease the total amount that the
plan sponsor pays for the drug, i.e., all pharmacy price concessions. This estimate must also
reflect the rebate or other price concession amount that the plan sponsor expects to receive from a
pharmaceutical manufacturer or other non-pharmacy entity and has elected to apply to the
negotiated price.
Beginning January 1, 2025, Part D sponsors must report the estimated amount of remuneration
that the Part D sponsor is required to apply, or has elected to apply, to the negotiated price as a
reduction in the drug price made available to the beneficiary at the POS in the “Estimated
Remuneration at POS Amount (ERPOSA)” field. This estimate includes the rebate or other price
concession amount that the plan sponsor expects to receive from a pharmaceutical manufacturer
or other non-pharmacy entity and has elected to apply to the negotiated price. Beginning January
1, 2025, the ERPOSA field must not include pharmacy price concessions. Rather, as described in
#2 above, when the PDE File Layouts are expanded on January 1, 2025, CMS is adding the new
“Pharmacy Price
October 14, 2022 HPMS memorandum, Reporting Estimated Remuneration Applied to the Point-of-Sale Price,
available here.
5

6

Concessions at POS” dollar amount field where pharmacy price concessions will be separately
reported.
When there is no rebate or price concession made available to the beneficiary at the POS, this
field may be $0. This field must contain a positive dollar amount; the field may never be negative.
9) Submission Clarification Code 1-5
CMS is expanding the one existing “Submission Clarification Code” field to 5 “Submission
Clarification Code” fields that will allow Part D sponsors to report up to 5 instances of
clarification codes on the PDE record, to align with future versions of the NCPDP
Telecommunication Standard.
CMS is also expanding the 5 “Submission Clarification Code” fields from the current 2-character
length to 3 characters; i.e., from a format of X(2) to the new format of X(3), consistent with future
versions of the NCPDP Telecommunication Standard. Beginning January 1, 2025, a numeric value
or spaces may be reported in these fields; if an LTC-related value is reported, Patient Residence must
be "03". This change will become effective on January 1, 2025. Valid values that CMS will accept
are included in the PDE File Layouts’ Definition/Values column.
10) Dollar Amount fields
CMS is expanding all dollar amount fields to accommodate future potential million-dollar claims.
The size of these fields is expanding from 8 characters to 11 characters, i.e., from the existing
format of S9(6)V99 to a new format of S9(9)V99.
This change will become effective on January 1, 2025.
