HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

1 Introduction to Modified Pages
This document is addenda to the X12N Health Care Services Review — Request
for Review and Response Implementation Guide, originally published May 2000
as 004010X094. As a result of the post publication review process, items were
identified that could be considered impediments to implementation. These items
were passed to the X12N Health Care Work Group that created the original Implementation Guide for their review.
Modifications based on those comments were reflected in a draft version of the
Addenda to the X12N 004010X094 Implementation Guide. Since the X12N
004010X094 Implementation Guide is named for use under the Health Insurance
Portability and Accountability Act of 1996 (HIPAA), an NPRM Draft Addenda went
through a Notice of Proposed Rule Making (NPRM) comment process that began
on May 31, 2002. The Addenda reflects changes based on comments received
during the NPRM process and X12N’s own review processes. Only the modifications noted in the NPRM Draft Addenda were considered in the NPRM and X12N
review processes. The Addenda was approved for publication by X12N on October 10, 2002. When using the X12N Health Care Services Review — Request for
Review and Response Implementation Guide, originally published May 2000 as
004010X094 and incorporating the changes identified in the Addenda, the value
used in GS08 must be “004010X094A1".
Each of the changes made to the 004010X094 Implementation Guide has been
annotated with a note in red and a line pointing to the location of the change. For
convenience, the affected 004010X094 Implementation Guide page number is
noted at the bottom of the page. Please note that as a result of insertion or deletion of material Addenda pages may not begin or end at the same place as the
original referenced page. Because of this, Addenda pages are not page for page
replacements and the original pages should be retained.
Changes in the Addenda may have caused changes to the Data Element Dictionary and the Data Element Name Index (Appendix E in the original Implementation Guide), but these changes are not identified in the Addenda. Changes in the
Addenda may also have caused changes to the Examples and the EDI Transmission Examples (Section 4 in the original Implementation Guide), again these are
not identified in the Addenda.

004010X094A1 • 278
HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

Supplemental Service Review Information
Under some circumstances, UMOs may require additional patient information to
determine the medical necessity of the services requested. The 278 supports the
ability to reference paper documentation and to attach electronic documentation
associated with the current health care services review.
The 278 request contains a PWK segment that the requester can use to reference an attachment (paper, electronic, or other medium) associated with the current health care services review. The attachment may be transmitted in a separate X12 functional group (e.g.: 275 Attachment). Refer to Section 2.2.5 for more
information on attachments. Please note that the 275 functionality is not mandated by HIPAA.

2.1.4

Situational Data
Factors such as the type of certification requested, the condition of the patient,
and the individual UMO’s rules for processing certifications make it difficult to
identify a single set of data elements that are required for all types of certifications. To meet the divergent needs of the UMOs and requesters, this guide includes many data elements and segments marked “situational”. Wherever possible, this implementation guide includes notes indicating when to include a situational segment or element. If the segment or element does not have an explanatory note, interpret “situational” to mean “if the information is available and applicable to the certification request or response, include it.”

2.1.5

Service Review Decisions
The UMO must respond to each 278 transaction set received. If the UMO can
process the service review request, the UMO must return a 278 response that
contains an HCR segment at the Service Level (Loop 2000F) in the response to
indicate the status of the service review.

2.1.6

Rejected Transactions
Missing or incorrect application data on the 278 request can cause the UMO to
reject the transaction. For these requests, the UMO must return a 278 response
transaction that contains a AAA Request Validation segment at the appropriate
level to indicate why the UMO rejected the transaction.
The AAA segments in Loop 2000A (UMO) enable both the clearinghouse and the
reviewer to indicate when system availability issues prohibit routing of the request
for processing.

2.1.7

Trace Numbers and Transaction Identifiers
This implementation guide provides several methods to enable requesters, clearinghouses, and UMOs to trace the transaction or match the response to the original request. This section describes the segments and data elements that carry
these identifiers.

HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

2.1.7.1

ASC X12N • INSURANCE SUBCOMMITTEE
IMPLEMENTATION GUIDE

BHT03 - Submitter Transaction Identifier
BHT03 identifies the transaction at its highest level. This is particularly useful in
reconciling 278 rejection transactions that may not contain all of the HL Loops.
The receiver of the 278 request transaction (whether it is a clearinghouse or
UMO) must return this identifier in the 278 response BHT03.

2.1.7.2

TRN Segment
The Patient loop (Loop 2000C or Loop 2000D) and the Service loop (Loop
2000F) each contain a TRN segment. This segment enables organizations to
uniquely identify the request. The TRN at the Patient level uniquely identifies the
patient event request. The Service level TRN uniquely identifies the request at
its lowest logical level, the service. Both the requester (provider) and the clearinghouse can add a TRN segment to the request.
The requester (provider) can use this TRN segment to meet several needs. This
enables the requester to accomplish the following:
• uniquely identify this request within the provider’s environment
• uniquely identify each service requested. A single request transaction can contain requests for multiple services represented by multiple occurrences of Loop
2000F. This can generate more than one 278 response from the UMO. The UMO
might certify some of these services immediately and pend others for external review.
• match the associated response to the request

Text
Revised

• facilitate routing of this response in a large health care environment. For example, it might be necessary for the requester to identify the department within the
provider environment that originated the transaction.
Clearinghouses can provide their own trace numbers in a separate TRN segment
at the Patient level and at the Service level on the request to use for transaction
tracking and matching purposes.
If the TRN segment is used on the request, the UMO must return the trace information supplied with the request transaction in the response transaction.
UMOs can add a trace number in their own TRN segment at the Patient level
(Loop 2000C or Loop 2000D) and Service level (Loop 2000F) on the response.
The UMO cannot use this trace number to identify the certification to the requester.
If the 278 request transaction passes through more than one clearinghouse, the
second (and subsequent) clearinghouse may choose one of the following options:
1. If the second or subsequent clearinghouse needs to assign their own TRN segment they may replace the received TRN segment belonging to the sending clearinghouse with their own TRN segment. Upon returning a 278 response to the
sending clearinghouse, they must remove their TRN segment and replace it with
the sending clearinghouse’s TRN segment.

New Text
Added

8

2. If the second or subsequent clearinghouse does not need to assign their own
TRN segment, they should merely pass all TRN segments received in the 278 request back in the 278 response transaction. If the 278 request passes through a
clearinghouse that adds their own TRN in addition to a requester TRN, the clearinghouse will receive a response from the UMO containing two TRN segments

that contain the value “2" (Referenced Transaction Trace Number) in TRN01. If
the UMO has assigned a TRN, the UMO’s TRN will contain the value ”1" (Current
Transaction Trace Number) in TRN01. If the clearinghouse chooses to pass their
own TRN values to the requester, the clearinghouse must change the value in
their TRN01 to “1" because, from the requester’s perspective, this is not a referenced transaction trace number.
New Text Added

2.1.7.3

A TRN segment at the patient level (Subscriber or Dependent) is required if
the provider needs to uniquely identify this patient event.

Patient Account Number
The requester (provider) can supply the patient account number as a supplemental identifier for the patient on the request. This value is carried in a REF segment
where REF01 = “EJ” in Loop 2000C - Subscriber or Loop 2000D - Dependent,
whichever is the patient. This information is optional for the requester. However if
the UMO receives the patient account number, they must return it in the 278 response transaction.

2.1.8

Disclaimers
This implementation guide does not support the transmission of general disclaimers as part of the transaction. Trading partners must handle these disclaimers outside of this EDI transaction and should identify procedures for handling these disclaimers in their trading partner agreements.

2.1.9
New Sub-section
Added

Additional Patient Information
Some health care service reviews may require additional information about the
patient that is not supported in the 278 transaction. This implementation guide includes a PWK segment to identify this additional patient information. On the 278
request, the PWK segment enables the requester to reference paper documentation or to attach electronic documentation containing additional patient information associated with the services requested. The requester may provide additional information about the patient at the Patient level and/or specific information
relevant to the service at the Service level.
In the 278 response, the UMO can indicate in the HCR segment that the review
outcome is pended for additional medical necessity information. The UMO can
use the PWK segment on a pended response to identify additional documentation required to complete the health care services review. The UMO can request
information about the patient using the PWK segment at the Patient level and/or
about the service using the PWK segment at the Service level.
In addition to the PWK segment, the UMO can use the HI segment at the Patient
level and/or the HI segment at the Service level of the response to specify codes
that identify the specific information that the UMO requires from the provider to
complete the medical review. On the response, the HI segment supports the use
of codes supplied from the Logical Observation Identifier Names and Codes
(LOINC® ) List. These codes identify high-level health care information groupings,
specific data elements, and associated modifiers.
The LOINC lists are external to ASC X12 standards. See Appendix C, External
Code Sources, for instructions about how to obtain these lists. LOINC® is a registered trademark of Regenstrief Institute and the LOINC Committee.

The Header level, Table 1, contains the purpose code for the transaction set as
well as date and time stamps. For this implementation guide, BHT02 is either Request (13) or Response (11).
The Detail level, Table 2, contains all data relating to the requested transaction,
including transaction participants, the patient, all providers, and services detail information. Table 2 uses a hierarchical data structure. For the types of business
transactions that this implementation guide addresses, the following HL levels apply:
Loop 2000A contains the UMO
Loop 2000B contains the Requester
Loop 2000C contains the Subscriber
Loop 2000D contains the Dependent
Loop 2000E contains the Service Provider
Loop 2000F contains the Services
The following are sample Table 2 configurations.

NOTE
For the request/response scope of this implementation guide, the use of UMO, requester, subscriber, dependent, and service provider is consistent and stable
across all transactions. Because the use of these levels is consistent, these levels are described one time. Because the use of the service level differentiates the
transaction’s use, this level is redefined several times to provide the reader with
appropriate information and examples.

Transaction Participants (Loop 2000A, Loop

PRV Segment
The PRV segment enables the requester to specify the referring provider’s role in
the care of the patient and to indicate the referring provider’s specialty. Use this
segment if the UMO requires this additional information to determine if the referring provider is authorized to request these services for this patient.

2.2.2

Patient (Loop 2000C and Loop 2000D)
Subscriber Loop 2000C and Dependent Loop 2000D identify the patient. Loop
2000C is always required. Loop 2000D is used only when necessary to identify a
patient who is a dependent. Figure 7. Subscriber and Dependent Levels shows
the structure of these loops.
When the subscriber is the patient or when the patient has a unique identification
number (different from the subscriber), only Loop 2000C is used. This situation is
common when an insurance company issues a unique insurance identification
card to each individual insured. In all other cases, Loop 2000C is used to identify
the subscriber. Loop 2000D is used to identify the subscriber’s dependent, who is
the patient. This structure is more common in traditional group insurance where a
patient is uniquely identified within the primary subscriber identifier.

Identifying the Subscriber/Patient
In Subscriber Name Loop 2010CA, the member ID (NM108/NM109) is required
and may be adequate to identify the subscriber to the UMO. However, the UMO
can require additional information. The maximum data elements that the UMO
can require to identify the subscriber, in addition to the member ID, are as follows:
Subscriber Last Name (NM103)
Subscriber First Name (NM104)
Subscriber Birth Date (DMG01 and DMG02).
The data requirements are the same for a dependent patient who has a unique
identification number (different from the subscriber).
Identifying the Dependent
The Dependent Loop (2000D) is required in addition to Loop 2000C if the dependent does not have a unique (different from the subscriber) member ID. The
maximum data elements in Loop 2010DA that can be required by a UMO to identify a dependent are as follows:
Dependent Last Name (NM103)
Loop ID Changed
Dependent First Name (NM104)
Dependent Birth Date (DMG01 and DMG02).

Use the TRN segment in Loop 2000C only if the subscriber is the patient. This
segment is required if the requester needs to assign a unique tracking number to
the patient event associated with this health care services review. It enables the
requester to:
• uniquely identify this patient event request
• trace the request

This TRN segment can occur a maximum of two times per Loop 2000C on the request; once for the provider and once for the clearinghouse. If the TRN segment
is used at this level on the request, the UMO must return it at the same level on
the response.
The TRN segment can occur a maximum of three times per Loop 2000C on the
response. The UMO can use this trace number to reference the request when

2.2.2.2.2

DTP Segments
The DTP segments carry dates relating to the patient’s current condition. This includes accident date, date of onset of current symptoms or illness, date of last
menstrual period, and estimated date of birth. Date diagnosed is associated with
a diagnosis and is contained in the HI segment.

2.2.2.2.3

HI Segment
The HI segment is used to convey diagnosis information. This information is always conveyed at the actual patient HL level. In the previous example, because
the subscriber is the patient, the HI segment appears at Loop 2000C (there
would be no Loop 2000D level). If Loop 2000D were used, this segment would
appear at the Loop 2000D level and not at Loop 2000C.

Added

The Logical Observation Identifier Names and Codes (LOINC®) code set was intended to increase the functionality of the 278 transaction set and it is not mandated by HIPAA and is only used when mutually agreed to by trading partners.

PWK Segment
Under some circumstances, the requester may need to provide additional information about the patient that is not supported in the 278. If the subscriber is the
patient, the requester can use this PWK segment to reference paper documentation or to attach electronic documentation containing additional patient information associated with this patient event. This implementation guide supports a
maximum of 10 occurrences of the PWK segment at the Patient (Subscriber or
Dependent) level.
The UMO can use the PWK segment on a pended response to identify additional
documentation required to complete the medical review.

NOTE:
The PWK segment also occurs in the Service loop. Use the PWK segment in the
Service loop if you are requesting multiple services and the additional information
pertains to a specific service and not to all the services requested.

Sub-section Name Changed

The Loop 2010CA NM1 segment is used to convey the subscriber’s name and
identification number. In the preceding example, this is also the name of the patient. This segment should always carry the primary identification number for the
insured. The REF segment in Loop 2010CA should be used only to transmit secondary identification numbers. In the NM1 segment, the identification number
transmitted is the primary member identifier used by the UMO. In most cases the
REF segment contains a supplemental member identifier used by the UMO. However, it can carry a patient identifier, such as a Patient Account Number, used by
the requester. If Loop 2010CA of the request contains a REF segment where
REF01 = “EJ” (Patient Account Number), the UMO must return the same REF
segment on the response.
The Loop 2010CB NM1 and associated N3, N4, and PER segments are used
only on the response. This loop enables the UMO to specify UMO contact information for the additional patient information requested in the UMO’s 278 response. This segment is used in the response at this level only when all of the following conditions are present.
• The subscriber is the patient
• The UMO has requested additional patient information at this level of the response
• The contact information for the additional patient information response differs
from the information provided in the UMO Name Level (Loop 2010A) of the 278

Dependent is the Patient
In those cases when the dependent is the patient and has not been issued a
unique identification number, both Loop 2000C and Loop 2000D are required.
Loop 2000C conveys insurance information and Loop 2000D conveys patient-related information. Until the HIPAA Unique Patient Identifier is mandated, if the patient is a dependent of a subscriber and does not have a unique member ID, the
maximum data elements that can be required by a UMO in loop 2010CA and
2010DA to identify a patient are:
Loop 2010CA
Subscriber’s Member ID

Loop ID Changed

Loop 2010DA
Patient’s First Name
Patient’s Last Name

If all four of these elements are present the UMO must generate a response if the
patient is in the UMO’s database. All UMOs are required to support the above
search option if their system does not have unique Member Identifiers assigned
to dependents. Figure 7, Subscriber and Dependent Levels, presents Loop
2000C and Loop 2000D.
The following example demonstrates a sufficient way of identifying a patient who

2.2.4

Services (Loop 2000F)
The Loop 2000F hierarchical level is used to identify the services requested for the
identified patient and to be supplied by the provider identified in Loop 2000E. Loop
2000F is used also to convey the outcome of the service review request in the service
response. Figure 9, Services Level, presents the Service Loop 2000F.
The service level of this transaction allows the inclusion of various patient condition or certification reason indicators. For example, a provider can specify the reason a request may have been delayed and not made within the timeframe required by a UMO.
Factors such as the type of certification request, the condition of the patient, and
the individual UMO’s business rules for processing certifications make it difficult
to identify a single set of data elements that are required for all types of certifications. If the information is available and applicable to the certification request or
response, include it.

on the segments as illustrated in figure 9.

2.2.4.1

Specialty Care Referrals
Specialty care referrals encompass those transactions where a provider requests
permission to refer or send a patient to another provider, generally a specialist.
These types of transactions generally are shared between a primary care physician and a UMO. However, they may just as easily be shared between any two
providers or UMOs.

UM01 = SC (Specialty Care Review)
UM02 = I (Initial Request)
UM09 = Y (Provider has a Signed Statement Permitting Release of Medical Billing Data Related to a Claim)
Other data elements in this segment carry additional information about the type
of request and the condition of the patient. Value these additional data elements
only if they provide information relevant to the medical decision.
2.2.4.1.1.2

HSD Segment and HI Segments
The HSD and HI segments are used according to need, either individually or in
conjunction with each other, to describe the service and/or quantity of service being requested.
The HSD segment is used to identify a number of visits. The following example indicates two visits.

HSD*VS*2~
HSD01 = VS (Visits)
HSD02 = 2
The HSD segment can also be used to identify a delivery pattern. The following
example indicates a pattern of three hours per week for four months.

HSD01 = HS (Hours)
HSD02 = 3
HSD03 = WK (Per week)

2.2.4.1.2

Response
A response transaction is used to indicate approval, approval with modification,
or denial of a previous request. Note that the service level segments contained in
a response transaction can vary from the requested level of service. For example, a primary care provider (PCP) may request ten visits to a specialist for a patient. However, the UMO may decide to approve only eight visits (perhaps the
maximum remaining benefit).
The HCR segment is required to provide the results of the review as well as an
associated reference number.

This set of values indicates approval of the request in full. Note that the original
service level details respecting the services requested are returned so that there
is no confusion as to what is being approved.
A reference number 0081096G is supplied and is critical if the provider wishes to

2.2.4.2.1.2

HSD and HI Segments
In a single 2000F service loop, the requester can specify multiple procedures associated with a single treatment. The HI Procedures segment can carry up to 12
procedure codes (HI01 through HI12). All the procedures specified must relate to
one episode of care. The requester can use the HSD segment to specify a delivery pattern for that episode of care to indicate that all the procedures specified
must occur within a single episode, but that episode can be repeated.
Each patient request can handle multiple 2000F loops. This means that the request can handle different services associated with a single patient event.

TRN Segment
The TRN segment enables the requester to assign a unique trace number to
each service (Loop 2000F) requested for a patient. The requester can use this to
trace the transaction or match the response to the request. In situations where
the request contains multiple service loops, the UMO might return a medical decision on some services immediately and pend others for review. In this case, the final decisions on each service may be returned by the UMO at different times.
Use of trace numbers at this level can facilitate matching these different responses to the original request.
The clearinghouse can also add a trace number at this level on the request.
Therefore, this TRN segment can occur a maximum of two times per Loop 2000F

segment is used at this level on the request, the UMO must return it at the same
level on the response.
Paragraph
Changed

The TRN segment can occur a maximum of three times per Loop 2000F on the
response. UMOs can add their own trace numbers to the response for tracking
purposes. The UMO cannot use this trace number as the certification number.
The segment is supplied solely for the convenience of the organization that originated it.
This guide’s authors recommend that requesters use this TRN segment.

2.2.4.4.2

AAA Segment
The AAA and HCR segments are used only in the response. If Loop 2000F is present, either the AAA segment or the HCR segment must be returned. If the UMO
was unable to review the request due to missing or invalid application data at this
level, the UMO must return a 278 response containing a AAA segment at this
level. It identifies the primary error condition in Loop 2000F of the original request
that prohibits processing of the original request.

2.2.4.4.3

HCR Segment
The HCR segment is required if the UMO has reviewed the request. It provides
information on the outcome of the medical review. If the request has been certified in total or certified as modified, the UMO must return a certification number in
this segment. This number identifies the certification to the requester. If the request has been pended, denied, or does not require a medical decision, HCR03
conveys the reason for the non-certification or other status of the request.

2.2.4.4.4
New Sub-section
Added

PWK Segment
Under some circumstances, the requester may need to provide additional information about the patient that is not supported in the 278. The requester can use
this PWK segment to reference paper documentation or to attach electronic documentation containing additional patient information associated with the services
requested in this Service loop. This implementation guide supports a maximum
of 10 occurrences of the PWK segment at the Service level.
The UMO can use the PWK segment on a pended response to identify additional
paper or electronic documentation required to complete the medical review for
the services requested in this loop.

NOTE:
The PWK segment also occurs in the Patient loop (Loop 2000C or Loop 2000D).
Use the PWK segment in the Service loop if you are requesting multiple services
and the additional information pertains to a specific service and not to all the services requested.

2.2.4.4.5
New Sub-section
Added

NM1 Loop
The Loop 2010F NM1 and associated N3, N4, and PER segments are used only
on the response. This loop enables the UMO to specify UMO contact information
for the additional service information requested in the PWK segment(s) in the
same Service level (Loop 2000F) in the UMO’s 278 response. This segment is
used in the response at this level only when all the following conditions are present.
• The UMO has requested additional service information at this level

278 Support for Additional Service Review
Information
Section 2 of this guide describes the health care services review information that
the requester and UMO can house within the 278 transaction (ST to SE). It also
describes segments and data elements that enable both the requester and the
UMO to reference additional information associated with a health care services
review that is not contained within the 278. This section provides guidelines for
using these segments and data elements.

Background on the Need Addressed
Under some circumstances, UMOs may require additional patient information to
determine the medical necessity of the services requested. This additional information concerns patient condition or service detail data not supported in the 278
(ST to SE). Depending on the type of health care services review, the requester
might know of additional information required of the UMO at the time the request
is initiated. Or, when the UMO receives the health care services review request,
the UMO may determine that additional information is required to complete the review.

Attaching Additional Information to the 278 Request
The 278 request contains a PWK segment that the requester can use to reference an attachment (paper, electronic, or other medium) associated with the current health care services review. The attachment may be transmitted in a separate X12 functional group (e.g.: 275 Attachment).

PWK Segments
The 278 request supports 10 occurrences of the PWK segment at the Patient
level (Loop 2000C and Loop 2000D) and at the Service level (Loop 2000F). This
enables the requester to attach up to 10 items pertaining to the patient’s condition and/or up to 10 items pertaining to each occurrence of Loop 2000F of the request.

TRN Segments
In addition to the PWK segment, the 278 supports a TRN segment at the Patient
level and at the Service level. The Patient level TRN segment (Patient Event
Tracking Number) is required if the requester needs to assign a unique trace
number to the patient event request. This enables the requester to
• uniquely identify this patient event request
• reconcile the request
• match the response to the request

IMPLEMENTATION GUIDE

• reference this request in any associated attachments containing additional patient information related to this patient event request.
The Service level TRN Segment (Service Trace Number) is required if the request contains more than one Service level and the requester needs to track
each service level request. This enables the requester to
• uniquely identify each service level request
• reconcile this request with its associated service level response
• reference this request in any associated attachments containing additional information related to this service level request
The UMO can reference these numbers when requesting additional information
pertaining to the patient event or to the services requested.

2.2.5.2.3

Guidelines for Referencing Attachments
1.

The PWK segment is required if the requester has additional documentation
(electronic, paper, or other medium) associated with this health care services review that applies to the patient event and/or the services requested
and the 278 request (ST to SE) does not support this information.

2.

Use the PWK segment at the Patient level if the attachment pertains to this
patient event and/or all the services requested.

3.

Use the PWK segment at the Service level if the information pertains to a
specific service identified in Loop 2000F.

4.

The PWK segment is required to identify attachments that are sent electronically (PWK02 = EL) but are transmitted in another X12 functional group
(e.g., 275) rather than by paper. PWK06 is used to identify the attached
electronic documentation. The number in PWK06 should be referenced in
the electronic attachment.

New Sub-section
Added

Please note that the 275 functionality is not mandated by HIPAA. 275 refers
to the X12N 275 Patient Information Transaction Set. At the time of this writing, there is no adopted standard implementation of the 275 for use with the
278 Health Care Services Review. A draft 275 Additional Information to
Support a Health Care Services Review implementation guide is in progress. The 275 can be used
1) If a new rule names the 275 Additional Information to Support a Health
Care Services Review as a standard for use with this implementation
of the 278.
2) For business uses of the 278 not covered under HIPAA. Use of the
275 should be mutually agreed to by trading partners.
3) To increase the functionality of the 278 request provided that it is
understood that this functionality is not mandated by HIPAA and must
be mutually agreed to by trading partners.
5.

The requester can also use the PWK segment to identify paperwork that is
held at the provider’s office and is available upon request by the UMO (or
appropriate entity).

HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

Requesting Additional Information on the 278
Response
When responding to a 278 request, the UMO might determine that additional information is required to complete the health care services review. The 278 response enables the UMO to
• indicate that the review outcome is pended for additional medical necessity information
• request this additional information by referencing paperwork that the requester
must complete or by specifying codified information that the requester must provide
• identify a specific contact or destination for the response to this request for additional information

2.2.5.3.1
New Sub-section
Added

BHT Segment
In the BHT segment, BHT02 identifies the purpose of the 278 transaction and
BHT06 identifies the type. A 278 response that contains a request for additional
information must specify the following values:
BHT02 = 11 (Response)
BHT06 = AT (Administrative Action)

2.2.5.3.2
New Sub-section
Added

HCR Segment
If the UMO system can process the service review request, the UMO must return
a 278 response that contains an HCR segment at the Service Level (Loop
2000F) in the response to indicate the status of the service review. The UMO
must value the HCR segment to indicate that the review outcome has been
pended for additional medical necessity information. If the UMO uses the 278 response to request this additional information, the UMO system must value the
HCR segment as follows:

HCR*A4**90~
Where:
HCR01 = “A4" (pended)
HCR03 = “90" (Requested Information Not Received)

2.2.5.3.3
New Sub-section
Added

PWK Segments
The UMO can use the PWK segment on a pended response to identify additional
documentation required to complete the health care services review. The UMO
can request information about the patient using the PWK segment at the Patient
level (Loop 2000C or Loop 2000D) and/or about the service using the PWK segment at the Service level (Loop 2000F). This implementation supports 10 occurrences of the PWK at the Patient level and at the Service level to enable the
UMO to request multiple attachments.
The UMO can use this segment to identify the type of documentation needed
such as forms that the provider must complete. The UMO can also indicate what
medium it has used to send these forms.

HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

ASC X12N • INSURANCE SUBCOMMITTEE
IMPLEMENTATION GUIDE

Guidelines for Use of PWK Segments
1.

The PWK segment is required if the UMO is requesting additional documentation (electronic, paper, or other medium) associated with this health care
services review that applies to the patient event and/or the services requested and the UMO does not use LOINC in the HI segments to request
this information.

2.

Paperwork requested at the patient level should apply to the patient event
and/or all the services requested. Use the PWK segment in the appropriate
Service loop if requesting medical necessity information for a specific service.

3.

This PWK segment is required to identify requests for specific data that are
sent electronically (PWK02 = EL) but are transmitted in another X12 functional group rather than by paper or using LOINC in the HI segments of the
response. PWK06 is used to identify the attached electronic questionnaire.
The number in PWK06 should be referenced in the corresponding electronic attachment.

NOTE:
At the time of this writing, there is no adopted standard implementation or
draft implementation of another X12 functional group (such as the 277) for
use with the 278.
4.

2.2.5.3.4
New Sub-section
Added

This PWK segment should not be used if the requester should have provided the information within the 278 request (ST-SE) but failed to do so. In
this case the UMO should use the AAA segments in the 278 response to indicate the data that is missing or invalid.

HI Segments
In addition to or in place of the PWK segment, the UMO can use the HI Diagnosis segment at the Patient level and/or the HI Procedures segment at the Service
level of the pended response to specify codes that identify the specific information that the UMO requires from the provider to complete the medical review. On
the response, the HI segment supports the use of codes supplied from the Logical Observation Identifier Names and Codes (LOINC®) List. These codes identify
high-level health care information groupings, specific data elements, and associated modifiers.
The UMO can use each occurrence of the Health Care Code Information composite (C022) in the HI segment to specify codes that identify the information
needed. In the C022 composite, data elements 1270 and 1271 support the
LOINC. Each HI segment supports 12 occurrences of the C022 composite.
LOINC codes are used to request specific information. LOINC modifier codes are
used to qualify the scope of the request for information. For example, LOINC
code 18657-7 requests the Rehabilitation treatment plan, plan of treatment (narrative). A LOINC modifier code of 18803-7 would qualify the requested information
to include all data of the selected type that represents observations made 30
days or fewer before the starting date of service.
The LOINC lists are external to ASC X12 standards. See Appendix C, External
Code Sources, for instructions about how to obtain these lists. LOINC® is a registered trademark of Regenstrief Institute and the LOINC Committee.
To request additional information using LOINC, value the HI segment as follows:

HEALTH CARE SERV. REVIEW - REQUEST FOR REVIEW & RESPONSE

HI*LOI:18657-7*LOI:18803-7~
Where “LOI” indicates that the code list used is Logical Observation Identifier
Names and Codes and 18657-7 is the high-level grouping and 18803-7 is the
modifier.
Guidelines for Use of LOI (LOINC) HI Segments
1.

The Logical Observation Identifier Names and Codes (LOINC®) code set
was intended to increase the functionality of the 278 transaction set and it is
not mandated by HIPAA and is only used when mutually agreed to by trading partners.

2.

Even if the trading partners can accommodate the use of LOINC on the 278
response containing the request for additional information, the UMO cannot
require that the original requester respond to this request using LOINC in
the follow-up response.

3.

LOINC specified in the HI Diagnosis segment at the Patient level should apply to the patient event and/or all the services requested. Use the HI Procedures segment in the appropriate Service loop if using LOINC to request
medical necessity information for specific services or procedures.

4.

If the LOINC request pertains to a specific diagnosis code or procedure
code, place the specific diagnosis or procedure code in the HI C022 composite that precedes the HI C022 composite(s) containing the LOINC. For
example:

HI*BO:490000*LOI:18657-7*LOI:18803-7~
Where BO:49000 identifies the procedure for which additional information is
required.
The Patient level supports only one occurrence of the HI Diagnosis segment. If the original request contained more than six diagnosis codes and
you are using LOINC to request additional information for each diagnosis
code or if you need to specify multiple questions/LOINC codes you cannot
exceed the limit of 12 occurrences of the C022 composite. Similarly, the
Service level supports only one occurrence of the HI Procedures segment.
However, the Service level can repeat. So, you can use multiple occurrences of Loop 2000F, if necessary, to accommodate more than 12 occurrences of the C022 composite.
5.

2.2.5.3.5
New Sub-section
Added

OCTOBER 2002

LOINC should not be used if the requester should have provided the information in the 278 request (ST-SE) but failed to do so. In this case the UMO
should use the AAA segments in the 278 response to indicate the data that
is missing or invalid.

NM1 Loops - Additional Information Contact Name
The 278 response includes NM1 loops to identify the person, office location, or
other destination to route the response to the UMO request for additional information. NM1 Loop 2010CB and NM1 Loop 2010DB identify additional patient information contact name, address, and communication number information and are
intended for use with requests for additional information contained in the PWK or
HI segments at the Patient level. NM1 Loop 2010F identifies additional service information contact name, address, and communication number information for

use with requests for additional information contained in the PWK or HI segments
at the Service level.
Guidelines for Use of NM1 Loops
1.

Information in this loop overrides information supplied in the UMO Name
NM1 loop (Loop 2010A).

2.

Use this NM1 loop only if
a. the destination for the response to the request for additional patient
information differs from the information specified in the UMO Name
NM1 loop (Loop 2010A).
b. either the PWK segment or HI segment in the associated loop contain
a request for additional information.

New Sub-section
Added

2.2.5.3.6

c. the request for additional information is not transmitted in another X12
functional group where PWK02 = EL.
3.

This NM1 segment is required if this loop is used.

TRN Segments
The UMO must return the trace information supplied with the request transaction
in the response transaction. The UMO must return the Patient Event Tracking
Number and, if used, the Service Trace Number in the appropriate location of the
response. If the UMO has requested additional information at the Patient level or
at the Service level, the UMO should retain the Patient Event Tracking Number or
Service Trace Number from the request.
In addition, UMOs can add a trace number in their own TRN segment at the Patient level (Loop 2000C or Loop 2000D) or at the Service level (Loop 2000F) on
the response.

2.2.5.4
New Sub-section
Added

Responding to a Request for Additional Information
If the 278 response contains a request for additional information, that request
must be specified either in LOINC® or in a separate attachment as specified in
the PWK segment of the response.
In either case, the appropriate reply to a 278 response containing a request for
additional information is not another 278.
The LOINC® code set was intended to increase the functionality of the 278 transaction set and it is not mandated by HIPAA and is only used when mutually
agreed to by trading partners. If LOINC® is used in the UMO response it is assumed that the trading partners have agreed on the appropriate format for the follow-up reply. This guide does not require a provider to respond to this codified request for additional information by using EDI or, specifically, by using another
X12 functional group. However, if the provider wants to respond using an EDI
transaction, the preferred EDI transaction method is a 275. Otherwise it is assumed that the provider will elect a non-EDI method to respond to the request for
additional information. Use of 275 functionality with the 278 is not mandated by
HIPAA and is only used when mutually agreed to by trading partners.
If the PWK segment is used, it indicates that the request for additional information is contained in a non-EDI format such as fax, email, paper mail, or voicemail.

1. This TRN segment is required if the subscriber is the patient and the
requester needs to assign a unique trace number to the patient event
request. This enables the requester to
• uniquely identify this patient event request
• trace the request
• match the response to the request
• reference this request in any associated attachments containing
additional patient information related to this patient event request.

132

2. If the transaction is routed through a clearinghouse, the
clearinghouse may add their own TRN segment. If the transaction
passes through multiple clearinghouses, and the second
clearinghouse needs to assign their own TRN segment, they must
replace the TRN from the first clearinghouse and retain it to be
returned in the 278 response. If the second clearinghouse does not
need to assign a TRN segment, they should pass all received TRN
segments.

3. Each trace number provided in the TRN segment at this level on the
request must be returned by the UMO in the TRN segment at the
corresponding level of the response.

1. This TRN segment is required if the dependent is the patient and the
requester needs to assign a unique trace number to the patient event
request. This enables the requester to
• uniquely identify this patient event request
• trace the request
• match the response to the request
• reference this request in any associated attachments containing
additional patient information related to this patient event request.

2. If the transaction is routed through a clearinghouse, the
clearinghouse may add their own TRN segment. If the transaction
passes through multiple clearinghouses, and the second
clearinghouse needs to assign their own TRN segment, they must
replace the TRN from the first clearinghouse and retain it to be
returned in the 278 response. If the second clearinghouse does not
need to assign a TRN segment, they should pass all received TRN
segments.

3. Each trace number provided in the TRN segment at this level on the
request must be returned by the UMO in the TRN segment at the
corresponding level of the response.

1. This PWK segment is required if the requester has additional
documentation (electronic, paper, or other medium) associated with
this health care services review that applies to the patient event
and/or all the services requested. This PWK segment should not be
used if
a. the 278 request (ST-SE) supports this information in its segments
and data elements, or
b. the 278 request (ST-SE) does not support this information and the
needed information pertains to a specific service identified in Loop
2000F and not to all the services requested.

2. This PWK segment is required to identify attachments that are sent
electronically (PWK02 = EL) but are transmitted in another X12
functional group rather than by paper or other medium. PWK06 is

1. Use this segment to assign a unique trace number to this service
request. It is recommended that requesters assign a unique trace
number to each service request. The requester can send one TRN
segment in each service level (Loop 2000F) on the request to aid in
the reconciliation of the 278 response.

132

2. If the transaction is routed through a clearinghouse, the
clearinghouse may add their own TRN segment. If the transaction
passes through multiple clearinghouses, and the second
clearinghouse needs to assign their own TRN segment, they must
replace the TRN from the first clearinghouse and retain it to be
returned in the 278 response. If the second clearinghouse does not
need to assign a TRN segment, they should pass all received TRN
segments.

3. Each trace number provided in the TRN segment at this level on the
request must be returned by the UMO in the TRN segment at the
corresponding level of the response.

4. If the request contains more than one occurrence of Loop 2000F and
the requester needs to uniquely identify each service level request
this TRN segment is required in each Service loop.

DEFINITION

Response - No Further Updates to Follow
Use this code to indicate that this is a final
response. If the final response reports a medical
decision it contains an HCR01 value of A1, A3, A6,
or NA in Loop 2000F. This indicates that no
additional EDI responses are necessary or
forthcoming from the UMO in relation to the original
request.

1226

Note: If you use HCR01 = CT to indicate a non-EDI
delivery of the medical decision, use it in
combination with BHT06 = 18.

1227

Use this code to indicate that the final medical
decision is pending further review. A pended
response contains an HCR01 value of A4 or CT.
This, in combination with BHT06 = 19, indicates that
the final EDI response will be delivered later.

3. If the 278 request transaction passes through more than one
clearinghouse, the second (and subsequent) clearinghouse may
choose one of the following options.
If the second or subsequent clearinghouse needs to assign their own
TRN segment they may replace the received TRN segment belonging
to the sending clearinghouse with their own TRN segment. Upon
returning a 278 response to the sending clearinghouse, they must
remove their TRN segment and replace it with the sending
clearinghouse’s TRN segment.
If the second or subsequent clearinghouse does not need to assign
their own TRN segment, they should merely pass all TRN segments
received in the 278 response transaction.
4. If the 278 request passes through a clearinghouse that adds their own
TRN in addition to a requester TRN, the clearinghouse will receive a
response from the UMO containing two TRN segments that contain
the value “2" (Referenced Transaction Trace Number) in TRN01. If the
UMO has assigned a TRN, the UMO’s TRN will contain the value ”1"
(Current Transaction Trace Number) in TRN01. If the clearinghouse
chooses to pass their own TRN values to the requester, the
clearinghouse must change the value in their TRN01 to “1" because,
from the requester’s perspective, this is not a referenced transaction
trace number.

1. Required if valued on the request and used by the UMO to render a
decision. If the response has not been rendered and this segment is
used to request additional information associated with a specific
diagnosis, place the specific diagnosis code in the HI C022 composite
that precedes the HI C022 composite(s) containing the LOINC. If the
original request contained more than six diagnosis codes and you are
using LOINC to request additional information for each of these
diagnosis codes or if you need to specify multiple questions/LOINC
codes per diagnosis you cannot exceed the limit of 12 occurrences of
the C022 composite.

3. The UMO can use each occurrence of the Health Care Code
Information composite (C022) to specify codes that identify the
specific information that the UMO requires from the provider to
complete the medical review. In the C022 composite, data elements
1270 and 1271 support the use of codes supplied from the Logical
Observation Identifier Names and Codes (LOINC®) List. These codes
identify high-level health care information groupings, specific data
elements, and associated modifiers.
The Logical Observation Identifier Names and Codes (LOINC®) code
set was intended to increase the functionality of the 278 transaction
set and it is not mandated by HIPAA and is only used when mutually
agreed to by trading partners.
Refer to Section 2.2.5 of this guide for more information on requesting
additional information in the 278 response.

1. This PWK segment is used only if the subscriber is the patient.

2. The UMO can use this PWK segment on the response to request
additional patient information. If the UMO has pended the decision on
this health care services review request (HCR01 = A4) because
additional medical necessity information is required (HCR03 = 90), the
UMO can use this segment to identify the type of documentation
needed such as forms that the provider must complete. The UMO can
also indicate what medium it has used to send these forms.

010
100

3. Paperwork requested at the patient level should apply to the patient
event and/or all the services requested. Use the PWK segment in the
appropriate Service loop if requesting medical necessity information
for a specific service.

011

0

4. This PWK segment is required to identify requests for specific data
that are sent electronically (PWK02 = EL) but are transmitted in
another X12 functional group rather than by paper or using LOINC in
the HI segments of the response. PWK06 is used to identify the
attached electronic questionnaire. The number in PWK06 should be
referenced in the corresponding electronic attachment.

011
100

5. This PWK segment should not be used if
a. the requester should have provided the information within the 278
request (ST-SE) but failed to do so. In this case the UMO should use
the AAA segments in the 278 response to indicate the data that is
missing or invalid.
b. the 278 request (ST-SE) does not support this information and the
needed information pertains to a specific service identified in Loop
2000F and not to all the services requested.
Refer to Section 2.2.5 for more information on using this segment.

3. If the 278 request transaction passes through more than one
clearinghouse, the second (and subsequent) clearinghouse may
choose one of the following options:
If the second or subsequent clearinghouse needs to assign their own
TRN segment they may replace the received TRN segment belonging
to the sending clearinghouse with their own TRN segment. Upon
returning a 278 response to the sending clearinghouse, they must
remove their TRN segment and replace it with the sending
clearinghouse’s TRN segment.
If the second or subsequent clearinghouse does not need to assign
their own TRN segment, they should merely pass all TRN segments
received in the 278 request in the 278 response transaction.
4. If the 278 request passes through a clearinghouse that adds their own
TRN in addition to a requester TRN, the clearinghouse will receive a
response from the UMO containing two TRN segments that contain
the value “2" (Referenced Transaction Trace Number) in TRN01. If the
UMO has assigned a TRN, the UMO’s TRN will contain the value ”1"
(Current Transaction Trace Number) in TRN01. If the clearinghouse
chooses to pass their own TRN values to the requester, the
clearinghouse must change the value in their TRN01 to “1" because,
from the requester’s perspective, this is not a referenced transaction
trace number.

Use this element to identify the organization that assigned this
trace number. If TRN01 is “2", this is the value received in the
original 278 request transaction. If TRN01 is ”1", use this
information to identify the UMO organization that assigned this
trace number.

1. Required if valued on the request and used by the UMO to render a
decision. If the response has not been rendered and this segment is
used to request additional information associated with a specific
diagnosis, place the specific diagnosis code in the HI C022 composite
that precedes the HI C022 composite(s) containing the LOINC. If the
original request contained more than six diagnosis codes and you are
using LOINC to request additional information for each of these
diagnosis codes or if you need to specify multiple questions/LOINC
codes per diagnosis you cannot exceed the limit of 12 occurrences of
the C022 composite.

Text Revised

2. It is recommended that the UMO retain the diagnosis information
carried on the request for use in subsequent health care service
review inquiries and notifications related to the original request.

New Note 3. Added

3. The UMO can use each occurrence of the Health Care Code
Information composite (C022) to specify codes that identify the
specific information that the UMO requires from the provider to
complete the medical review. In the C022 composite, data elements
1270 and 1271 support the use of codes supplied from the Logical
Observation Identifier Names and Codes (LOINC®) List. These codes
identify high-level health care information groupings, specific data
elements, and associated modifiers.
The Logical Observation Identifier Names and Codes (LOINC®) code
set was intended to increase the functionality of the 278 transaction
set and it is not mandated by HIPAA and is only used when mutually
agreed to by trading partners.
Refer to Section 2.2.5 of this guide for more information on requesting
additional information in the 278 response.

1. The UMO can use this PWK segment on the response to request
additional patient information. If the UMO has pended the decision on
this health care services review request (HCR01 = A4) because
additional medical necessity information is required (HCR03 = 90), the
UMO can use this segment to identify the type of documentation
needed such as forms that the provider must complete. The UMO can
also indicate what medium it has used to send these forms.

010
100
9

2. Paperwork requested at the patient level should apply to the patient
event and/or all the services requested. Use the PWK segment in the
appropriate Service loop if requesting medical necessity information
for a specific service.

011
100
0

3. This PWK segment is required to identify requests for specific data
that are sent electronically (PWK02 = EL) but are transmitted in
another X12 functional group rather than by paper or using LOINC in
the HI segments of the response. PWK06 is used to identify the
attached electronic questionnaire. The number in PWK06 should be
referenced in the corresponding electronic attachment.

011
100
1

4. This PWK segment should not be used if
a. the requester should have provided the information within the 278
request (ST-SE) but failed to do so. In this case the UMO should use
the AAA segments in the 278 response to indicate the data that is
missing or invalid.
b. the 278 request (ST-SE) does not support this information and the
needed information pertains to a specific service identified in Loop
2000F and not to all the services requested.
Refer to Section 2.2.5 for more information on using this segment.

3. The UMO can use each occurrence of the Health Care Code
Information composite (C022) to specify codes that identify the
specific information that the UMO requires from the provider to
complete the medical review. In the C022 composite, data elements
1270 and 1271 support the use of codes supplied from the Logical
Observation Identifier Names and Codes (LOINC®) List. These codes
identify high-level health care information groupings, specific data
elements, and associated modifiers.
The Logical Observation Identifier Names and Codes (LOINC®) code
set was intended to increase the functionality of the 278 transaction
set and it is not mandated by HIPAA and is only used when mutually
agreed to by trading partners.
4. If this segment is used to request additional information associated
with a specific procedure, place the specific procedure code in the HI
C022 composite that precedes the HI C022 composite(s) containing
the LOINC. If the original request contained more than six procedure
codes and you are using LOINC to request additional information for
each of these procedure codes or if you need to specify multiple
questions/LOINC codes per procedure you cannot exceed the limit of
12 occurrences of the C022 composite in this HI segment. If
necessary, use additional occurrences of Loop 2000F.

1. The UMO can use this PWK segment on the response to request
additional information that applies to the service(s) requested in this
Service loop. If the UMO has pended the decision on this health care
services review request (HCR01 = A4) because additional medical
necessity information is required (HCR03 = 90), the UMO can use this
segment to identify the type of documentation needed such as forms
that the provider must complete. The UMO can also indicate what
medium it has used to send these forms.

016

2. Additional information requested at the Service level should apply to a
specific service and/or all the services requested in this service loop.

3. This PWK segment is required to identify requests for specific data
that are sent electronically (PWK02 = EL) but are transmitted in
another X12 functional group rather than by paper or using LOINC in
the HI segments of the response. PWK06 is used to identify the
attached electronic questionnaire. The number in PWK06 should be
referenced in the corresponding electronic attachment.

011

4. This PWK segment should not be used if
a. the requester should have provided the information within the 278
request (ST-SE) but failed to do so. In this case the UMO should use
the AAA segments in the 278 response to indicate the data that is
missing or invalid.
b. the 278 request (ST-SE) does not support this information and the
needed information pertains to all the services requested and not to a
specific service. Use the PWK segment at the Patient level (Loop
2000C or Loop 2000D) if requesting medical necessity information that
applies to all the services requested
Refer to Section 2.2.5 for more information on using this segment.

IMPLEMENTATION GUIDE

Data elements are assigned a unique reference number. Each data element has
a name, description, type, minimum length, and maximum length. For ID type
data elements, this guide provides the applicable ASC X12 code values and their
descriptions or references where the valid code list can be obtained.
Each data element is assigned a minimum and maximum length. The length of
the data element value is the number of character positions used except as
noted for numeric, decimal, and binary elements.
The data element types shown in matrix A4, Data Element Types, appear in this
implementation guide.

Matrix A4. Data Element Types

A.1.3.1.1

Numeric
A numeric data element is represented by one or more digits with an optional
leading sign representing a value in the normal base of 10. The value of a numeric data element includes an implied decimal point. It is used when the position of the decimal point within the data is permanently fixed and is not to be
transmitted with the data.
This set of guides denotes the number of implied decimal positions. The representation for this data element type is “Nn” where N indicates that it is numeric
and n indicates the number of decimal positions to the right of the implied decimal point.
If n is 0, it need not appear in the specification; N is equivalent to N0. For negative values, the leading minus sign (-) is used. Absence of a sign indicates a positive value. The plus sign (+) should not be transmitted.
EXAMPLE
A transmitted value of 1234, when specified as numeric type N2, represents a
value of 12.34.
Leading zeros should be suppressed unless necessary to satisfy a minimum
length requirement. The length of a numeric type data element does not include
the optional sign.

A.1.3.1.2

Decimal
A decimal data element may contain an explicit decimal point and is used for numeric values that have a varying number of decimal positions. This data element
type is represented as “R.”
The decimal point always appears in the character stream if the decimal point is
at any place other than the right end. If the value is an integer (decimal point at
the right end) the decimal point should be omitted. For negative values, the leading minus sign (-) is used. Absence of a sign indicates a positive value. The plus
sign (+) should not be transmitted.

example, the commas in 1,000,000) is expressly prohibited. The length of a decimal type data element does not include the optional leading sign or decimal point.
EXAMPLE
A transmitted value of 12.34 represents a decimal value of 12.34.
New note

A.1.3.1.3

For implementation of this guide under the rules promulgated under the Health Insurance Portability and Accountability Act (HIPAA), decimal data elements in
Data Element 782 (Monetary Amount) will be limited to a maximum length of 10
characters including reported or implied places for cents (implied value of 00 after
the decimal point). Note the statement in the preceding paragraph that the decimal point and leading sign, if sent, are not part of the character count.

Identifier
An identifier data element always contains a value from a predefined list of codes
that is maintained by the ASC X12 Committee or some other body recognized by
the Committee. Trailing spaces should be suppressed unless they are necessary
to satisfy a minimum length. An identifier is always left justified. The representation for this data element type is “ID.”

A.1.3.1.4

String
A string data element is a sequence of any characters from the basic or extended
character sets. The significant characters shall be left justified. Leading spaces,
when they occur, are presumed to be significant characters. Trailing spaces
should be suppressed unless they are necessary to satisfy a minimum length.
The representation for this data element type is “AN.”

A.1.3.1.5

Date
A date data element is used to express the standard date in either YYMMDD or
CCYYMMDD format in which CC is the first two digits of the calendar year, YY is
the last two digits of the calendar year, MM is the month (01 to 12), and DD is the
day in the month (01 to 31). The representation for this data element type is “DT.”
Users of this guide should note that all dates within transactions are 8-character
dates (millennium compliant) in the format CCYYMMDD. The only date data element that is in format YYMMDD is the Interchange Date data element in the ISA
segment, and also used in the TA1 Interchange Acknowledgment, where the century can be readily interpolated because of the nature of an interchange header.

A.1.3.1.6

Time
A time data element is used to express the ISO standard time HHMMSSd..d format in which HH is the hour for a 24 hour clock (00 to 23), MM is the minute (00
to 59), SS is the second (00 to 59) and d..d is decimal seconds. The representation for this data element type is “TM.” The length of the data element determines the format of the transmitted time.
EXAMPLE
Transmitted data elements of four characters denote HHMM. Transmitted data
elements of six characters denote HHMMSS.
