Introduction

1.1

Scope

The CMS Encounter Data System (EDS) 837-P DME Companion Guide addresses how MAOs and other
entities conduct Professional DME supplier claims Health Information Portability and Accountability Act
(HIPAA) standard electronic transactions with CMS. The CMS EDS supports transactions adopted under
HIPAA, as well as additional supporting transactions described in this guide.
The CMS EDS 837-P DME Companion Guide must be used in conjunction with the associated 837-P
Implementation Guide (TR3) and the Encounter Data Front-End System (EDFES) CEM Edits Spreadsheets.
The instructions in the CMS EDS 837-P DME Companion Guide are not intended for use as a stand-alone
requirements document.
1.2

Overview

The CMS EDS 837-P DME Companion Guide includes information required to initiate and maintain
communication exchange with CMS. The information is organized in the sections listed below:
•

Contact Information: Includes telephone numbers and email addresses for EDS contacts.

•

Control Segments/Envelopes: Contains information required to create the ISA/IEA, GS/GE, and
ST/SE control segments in order for the EDS to support these transactions.

•

Acknowledgements and Reports: Contains information for all transaction acknowledgements
and reports sent by EDS.

•

Transaction Specific Information: Describes the details of the HIPAA X12N Implementation
Guides (IGs), using a tabular format. The tables contain a row for each segment with CMS and
IG specific information. That information may contain:
o

Limits on the repeat of loops or segments

o

Limits on the length of a simple data element

o

Specifics on a sub-set of the IG’s internal code listings

o

Clarification of the use of loops, segments, and composite or simple data elements

o

Any other information tied directly to a loop, segment, and composite or simple data
element pertinent to trading electronically with CMS.

In addition to the row for each segment, one (1) or more additional rows describe the EDS’ usage for
composite or simple data elements and for any other information.

1.3 Major Updates
1.3.1

EDS Acronyms

MAOs and other entities may reference Section 14.0, Table 19 for additional acronyms frequently used
by the EDS.
1.4

References

MAOs and other entities must use the ASC X12N IG adopted under the HIPAA Administrative
Simplification Electronic Transaction rule, along with CMS’ Encounter Data Participant Guides and EDS
Companion Guidelines, for development of EDS’ transactions. These documents are accessible on the
CSSC Operations website at www.csscoperations.com.
Additionally, CMS publishes the EDS’ submitter guidelines and application, testing documents, 837 EDS
Companion Guides and Encounter Data Participant Guides on the CSSC Operations website.
MAOs and other entities must use the most current national standard code lists applicable to the 5010
transaction. The code lists is accessible at the Washington Publishing Company (WPC) website at
http://www.wpc-edi.com
The applicable code lists are as follows:
• Claim Adjustment Reason Code (CARC)
• Claim Status Category Codes (CSSC)
• Claim Status Codes (CSC)
CMS provides X12 5010 file format technical edit spreadsheets for the 837-P and 837-I. The edits
included in the spreadsheets are provided to clarify the WPC instructions or add Medicare specific
requirements. In order to determine the implementation date of the edits contained in the
spreadsheet, MAOs and other entities should initially refer to the spreadsheet version identifier. The
version identifier is comprised of ten (10) characters as follows:
•

•
•

•

Positions 1-2 indicate the line of business:
o EA – Part A (837-I)
o EB – Part B (837-P)
Positions 3-6 indicate the year (e.g., 2011)
Position 7 indicates the release quarter month
o 1 – January release
o 2 – April release
o 3 – July release
o 4 – October release
Positions 8-10 indicate the spreadsheet version iteration number (e.g., V01-first iteration, V02second iteration)

The effective date of the spreadsheet is the first calendar day of the release quarter month. The
implementation date is the first business Monday of the release quarter month. Federal holidays that
potentially occur on the first business Monday are considered when determining the implementation

date. For example, the edits contained in a spreadsheet version of EB20113V01 are effective July 1,
2011 and implemented on July 5, 2011.

Due to system limitations, the combination of all ST/SE transaction sets per file cannot exceed certain
thresholds, dependent upon the connectivity method of the submitter. FTP and NDM users cannot
exceed 85,000 encounters per file. Gentran/TIBCO users cannot exceed 5,000 encounters per file. For
all connectivity methods, the TR3 allows no more than 5000 CLMs per ST/SE segment. The following
table demonstrates the limits due to connectivity methods:
CONNECTIVITY
FTP/NDM
Gentran/TIBCO

MAXIMUM NUMBER OF
ENCOUNTERS
85,000
5,000

MAXIMUM NUMBER OF
ENCOUNTERS PER ST/SE
5,000
5,000

Note: Due to system processing overhead associated with smaller numbers of encounters within the
ST/SE, it is highly recommended that MAOs and other entities submit larger numbers of encounters
within the ST/SE, not to exceed 5,000 encounters.
In an effort to support and provide the most efficient processing system, and to allow for maximum
performance, CMS recommends that FTP submitters’ scripts upload no more than one (1) file per five (5)
minute intervals. Zipped files should contain one (1) file per transmission. MAOs and other entities
837 DME Professional Companion Guide Version 22.0/May 2014

7

should refrain from submitting multiple files within the same transmission. NDM and Gentran/TIBCO
users may submit a maximum of 255 files per day.
3.2

File Structure – NDM/Connect:Direct and Gentran/TIBCO Submitters Only

NDM/Connect Direct and Gentran/TIBCO submitters must format all submitted files in an 80-byte fixed
block format. This means MAOs and other entities must upload every line (record) in a file with a length
of 80 bytes/characters.
Submitters should create files with segments stacked, using only 80 characters per line. At position 81
of each segment, MAOs and other entities must create a new line. On the new line starting in position
1, continue for 80 characters, and repeat creating a new line in position 81 until the file is complete. If
the last line in the file does not fill to 80 characters, the submitter should space the line out to position
80 and then save the file.
Note: If MAOs and other entities are using a text editor to create the file, pressing the Enter key will
create a new line. If MAOs and other entities are using an automated system to create the file, create a
new line by using a CRLF (Carriage Return Line Feed) or a LF (Line Feed).
For example the ISA record is 106 characters long:
ISA*00*
*00*
*ZZ*ENH9999
4*^*00501*000000031*1*P*:~

*ZZ*80887

*120430*114

The first line of the file will contain the first 80 characters of the ISA segment; the last 26 characters of
the ISA segment will be continued on the second line. The next segment will start in the 27th position
and continue until column 80.
Note to NDM/Connect:Direct Users: If a submitter has not established a sufficient number of
Generated Data Groups (GDGs) to accommodate the number of files returned from the EDFES, not all of
the EDFES Acknowledgement reports will be stored in the submitter’s system. To prevent this situation,
NDM/ Connect:Direct submitters should establish a limit of 255 GDGs in their internal systems.

Control Segments/Envelopes

4.1

ISA/IEA

The term interchange denotes the transmitted ISA/IEA envelope. Interchange control is achieved
through several “control” components, as defined in Table 1. The interchange control number is
contained in data element ISA13 of the ISA segment. The identical control number must also occur in
data element IEA02 of the IEA segment. MAOs and other entities must populate all elements in the
ISA/IEA interchange. There are several elements within the ISA/IEA interchange that must be populated
specifically for encounter data purposes. Table 1 provides EDS Interchange Control (ISA/IEA) specific
elements.
Note: Table 1 presents only those elements that provide specific details relevant to encounter data.
When developing the encounter data system, users should base their logic on the highest level of

specificity. First, consult the WPC/TR3. Second, consult the CMS edits spreadsheets. Third, consult the
CMS EDS 837-P Companion Guide. If the options expressed in the WPC/TR3 or the CEM edits
spreadsheet are broader than the options identified in the CMS EDS 837-P Companion Guide, MAOs and
other entities must use the rules identified in the Companion Guide.

The functional group is outlined by the functional group header (GS segment) and the functional group
trailer (GE segment). The functional group header starts and identifies one or more related transaction
sets and provides a control number and application identification information. The functional group
trailer defines the end of the functional group of related transaction sets and provides a count of
contained transaction sets.
MAOs and other entities must populate elements in the GS/GE functional group. There are several
elements within the GS/GE that must be populated specifically for encounter data collection. Table 2
provides EDS functional group (GS/GE) specific elements.

ST/SE

The transaction set (ST/SE) contains required, situational loops, unused loops, segments, and data
elements. The transaction set is outlined by the transaction set header (ST segment) and the
transaction set trailer (SE segment). The transaction set header identifies the start and identifies the
transaction set. The transaction set trailer identifies the end of the transaction set and provides a count
of the data segments, which includes the ST and SE segments. There are several elements that must be
populated specifically for encounter data purposes. Table 3 provides EDS’ transaction set (ST/SE)
specific elements.

submit EDS transactions using the most current transaction version.
The 837 Professional (DME) Data Element table identifies only those elements within the X12N
Implementation Guide that require comment within the context of EDS’ submission. Table 4 identifies
the 837 Professional Implementation Guide by loop name, segment name, segment identifier, data
element name, and data element identifier for cross reference. Not all of the data elements listed in
Table 4 are required; but if they are used, the table reflects the values CMS expects to see.

Acknowledgements and/or Reports

6.1

TA1 – Interchange Acknowledgement

The TA1 report enables the receiver to notify the sender when there are problems with the interchange
control structure. As the interchange envelope enters the EDFES, the EDI translator performs TA1
validation of the control segments/envelope. The sender will only receive a TA1 if there are syntax
errors in the file. Errors found in this stage will cause the entire X12 interchange to reject with no
further processing.
MAOs and other entities will receive a TA1 interchange report acknowledging the syntactical inaccuracy
of an X12 interchange header ISA and trailer IEA and the envelope’s structure. Encompassed in the TA1
is the interchange control number, interchange date and time, interchange acknowledgement code and
interchange note code. The interchange control number, date, and time are identical to those
populated on the original 837-I or 837-P ISA line, which allows for MAOs and other entities to associate
the TA1 with a specific file previously submitted.
Within the TA1 segment, MAOs and other entities will be able to determine if the interchange rejected
by examining the interchange acknowledgement code (TA104) and the interchange note code (TA105).
The interchange acknowledgement code stipulates whether the interchange (ISA/IEA) rejected due to
syntactical errors. An “R” will be the value in the TA104 data element if the interchange rejected due to
errors. The interchange note code is a numeric code that notifies MAOs and other entities of the
specific error. If a fatal error occurs, the EDFES generates and returns the TA1 interchange
acknowledgement report within 24 hours of the interchange submission. If a TA1 interchange control
structure error is identified, MAOs and other entities must correct the error and resubmit the
interchange file.
6.2

999 – Functional Group Acknowledgement

After the interchange passes the TA1 edits, the next stage of editing is to apply Implementation Guide
(IG) edits and verify the syntactical correctness of the functional group(s) (GS/GE). Functional groups
allow for organization of like data within an interchange; therefore, more than one (1) functional group
with multiple claims within the functional group can be populated in a file. The 999 acknowledgement
report provides information on the validation of the GS/GE functional group(s) and the consistency of
837 DME Professional Companion Guide Version 22.0/May 2014

16

the data. The 999 report provides MAOs and other entities information on whether the functional
group(s) were accepted or rejected.
If a file has multiple GS/GE segments and errors occurred at any point within one of the syntactical and
IG level edit validations, the GS/GE segment will reject, and processing will continue to the next GS/GE
segment. For instance, if a file is submitted with three (3) functional groups and there are errors in the
second functional group, the first functional group will accept, the second functional group will reject,
and processing will continue to the third functional group.
The 999 transaction set is designed to report on adherence to IG level edits and CMS standard syntax
errors as depicted in the CMS edit spreadsheet. Three (3) possible acknowledgement values are:
•
•
•

“A” – Accepted
“R” – Rejected
“P” - Partially Accepted, At Least One Transaction Set Was Rejected

When viewing the 999 report, MAOs and other entities should navigate to the IK5 and AK9 segments. If
an “A” is displayed in the IK5 and AK9 segments, the claim file is accepted and will continue processing.
If an “R” is displayed in the IK5 and AK9 segments, an IK3 and an IK4 segment will be displayed. These
segments indicate what loops and segments contain the error that needs correcting so the interchange
can be resubmitted. The third element in the IK3 segment identifies the loop that contains the error.
The first element in the IK3 and IK4 indicates the segment and element that contain the error. The third
element in the IK4 segment indicates the reason code for the error.
6.3

277CA – Claim Acknowledgement

After the file accepts at the interchange and functional group levels, the third level of editing occurs at
the transaction set level within the CEM in order to create the Claim Acknowledgement Transaction
(277CA) report. The CEM checks the validity of the values within the data elements. For instance, data
element N403 must be a valid nine (9)-digit ZIP code. If a non-existent ZIP code is populated, the CEM
will reject the encounter. The 277CA is an unsolicited acknowledgement report from CMS to MAOs and
other entities.
The 277CA is used to acknowledge the acceptance or rejection of encounters submitted using a
hierarchical level (HL) structure. The first level of hierarchical editing is at the Information Source level.
This entity is the decision maker in the business transaction receiving the X12 837 transactions
(EDSCMS). The next level is at the Information Receiver level. This is the entity expecting the response
from the Information Source. The third hierarchal level is at the Billing Provider of Service level; and the
fourth and final level is done at the Patient level. Acceptance or rejection at this level is based on the
WPC and the CMS edits spreadsheet. Edits received at any hierarchical level will stop and no further
editing will take place. For example, if there is a problem with the Billing Provider of Service submitted
on the 837, individual patient edits will not be performed. For those encounters not accepted, the

837 DME Professional Companion Guide Version 22.0/May 2014

17

277CA will detail additional actions required of MAOs and other entities in order to correct and resubmit
those encounters.
If an MAO or other entity receives a 277CA indicating an encounter rejected, the MAO or other entity
must resubmit the encounter until the 277CA indicates no errors were found.
If an encounter is accepted, the 277CA will provide the ICN assigned to that encounter. The ICN
segment for the accepted encounter will be located in 2200D REF segment, REF01=IK and REF02=ICN.
The ICN is a unique 13-digit number.
If an encounter rejects, the 277CA will provide edit information in the STC segment. The STC03 data
element will convey whether the HL structures accepted or rejected. The STC03 is populated with a
value of “WQ”, if the HL was accepted. If the STC03 data element is populated with a value of “U”, the
HL rejects and the STC01 data element will list the acknowledgement code.
6.4

MAO-001 – Encounter Data Duplicates Report

When the MAO-002 Encounter Data Processing Status Report is returned to an MAO or other entity, and
contains edit 98325 – Service Line(s) Duplicated, the EDPS will also generate and return the MAO-001
Encounter Data Duplicates Report. MAOs and other entities will not receive the MAO-001 report if
there are no duplicate errors received on submitted encounters.
The MAO-001 report is a fixed length report available in flat file and formatted report layouts. It
provides information for encounters and service lines that receive a status of “reject” and the specific
error message of 98325 – Service Line(s) Duplicated. MAOs and other entities must correct and
resubmit all encounters and/or service lines for edit 98325. The MAO-001 report allows MAOs and
other entities the opportunity to more easily reconcile these duplicate encounters and service lines.
6.5

MAO-002 – Encounter Data Processing Status Report

After a file accepts through the EDFES, the file is transmitted to the Encounter Data Processing System
(EDPS) where further editing, processing, pricing, and storage occurs. As a result of EDPS editing, the
EDPS will return the MAO-002 – Encounter Data Processing Status Report.
The MAO-002 report is a fixed length report available in flat file and formatted report layouts that
provide encounter and service line level information. The MAO-002 reflects two (2) statuses at the
encounter and service line level: “accepted” and “rejected”. Lines that reflect a status of “accept” yet
contain an error message in the Edit Description column are considered “informational” edits. MAOs
and other entities are not required to take further action on “informational” edits.
The ‘000’ line on the MAO-002 report identifies the header level and indicates either “accepted” or
“rejected” status. If the ‘000’ header line is rejected, the encounter is considered rejected and MAOs
and other entities must correct and resubmit the encounter. If the ‘000’ header line is “accepted” and
at least one (1) other line (i.e., 001 002 003 004) is accepted, then the overall encounter is accepted.

Reports File Naming Conventions

In order for MAOs and other entities to receive and identify the EDFES acknowledge reports (TA1, 999,
and 277CA) and EDPS MAO-002 Encounter Data Processing Status Report, specific reports file naming
conventions have been used. The file name ensures that the specific reports are appropriately
distributed to each secure, unique mailbox. The EDFES and EDPS have established unique file naming
conventions for reports distributed during testing and production.
6.6.1

EDFES Notifications

The EDFES distributes special notifications to submitters when encounters have been processed by the
EDFES, but will not proceed to the EDPS for further processing. These notifications are distributed to
MAOs and other entities, in addition to standard EDFES Acknowledgement Reports (TA1, 999, and
277CA) in order to avoid returned, unprocessed files from the EDS.
Table 10 provides the file type, EDFES notification message, and EDFES notification message description.
The file has an 80 character record length and contains the following record layout:
1. File Name Record
a. Positions 1 – 7 = Blank Spaces
b. Positions 8 – 18 = File Name:
c. Positions 19 – 62 = Name of the Saved File
d. Positions 63 – 80 = Blank Spaces
2. File Control Record
a. Positions 1 – 4 = Blank Spaces
b. Positions 5 – 18 = File Control:
c. Positions 19 – 27 = File Control Number
d. Positions 28 – 80 = Blank Spaces
3. File Count Record
a. Positions 1 – 18 = Number of Claims:
b. Positions 19 – 24 = File Claim Count
c. Positions 25 – 80 = Blank Spaces
4. File Separator Record
a. Positions 1 – 80 = Separator (----------)
5. File Message Record
a. Positions 1 – 80 = FILE WAS NOT SENT TO THE EDPS BACK-END PROCESS FOR THE
FOLLOWING REASON(S)
6. File Message Records
a. Positions 1 – 80 = File Message

Front-End Edits

CMS provides a list of the edits used to process all encounters submitted to the EDFES. The Fee-forService (FFS) Professional CEM Edits Spreadsheet identifies active and deactivated edits for MAOs and
other entities to reference for programming their internal systems and reconciling EDFES
Acknowledgement Reports. The edits for Professional DME submission are identified in the column
labeled “CEDI”.
The Professional CEM Edits Spreadsheet provides documentation regarding edit rules that explain how
to identify an EDFES edit and the associated logic. The Professional CEM Edits Spreadsheet also provides
a change log that lists the revision history for edit updates.
MAOs and other entities are able to access the Professional CEM Edits Spreadsheet on the CMS website
at https://www.cms.gov/Medicare/Billing/MFFS5010D0/Technical-Documentation.html and on the
CSSC Operations website at:

Deactivated Front-End Edits

Several CEM edits currently active in the FFS Professional CEM edits spreadsheet will be deactivated in
order to ensure that syntactically correct encounters pass front-edit editing. Table 11 provides a list of
the deactivated EDFESCEM edits. The edit reference column provides the exact reference for the
deactivated edits. The edit description column provides the Claim Status Category Code (CSCC), the
Claim Status Code (CSC), and the Entity Identifier Code (EIC), when applicable. The notes column
provides a description of the edit reason. MAOs and other entities should reference the WPC website at
www.wpc-edi.com for a complete listing of all CSCCs and CSCs.

Duplicate Logic

In order to ensure encounters submitted are not duplicates of encounters previously submitted, header
and detail level duplicate checking will be performed. If the header and/or detail level duplicate
checking that determines the file is a duplicate, the file will reject, and an error report will be returned
to the submitter.

837 DME Professional Companion Guide Version 22.0/May 2014

8.1

Header Level

When a file (ISA/IEA) is received, the system assigns a hash total to the file based on the entire ISA/IEA
interchange. The EDS uses hash totals to ensure the accuracy of processed data. The hash total is a
total of several fields or data in a file, including fields not normally used in calculations, such as the
account number. At various stages in processing, the hash total is recalculated and compared with the
original. If a file comes in later in a different submission, or a different submission of the same file, and
gets the same hash total, it will reject as a duplicate.
In addition to the hash total, the system also references the values collectively populated in ISA13, GS06,
ST02, and BHT03. If two (2) files are submitted with the exact same values populated as a previously
submitted and accepted file, the file will be considered a duplicate and the error message CSCC - A8 =
Acknowledgement / Rejected for relational field in error, CSC -746 = Duplicate Submission will be
provided on the 277CA.
8.2

Detail Level

Once an encounter passes through the Institutional or Professional processing and pricing system, it is
stored in an internal repository, the Encounter Operational Data Store (EODS). If a new encounter is
submitted that matches specific values on another stored encounter, the encounter will be rejected and
considered a duplicate encounter. The encounter will be returned to the submitter with an error
message identifying it as a duplicate encounter. Currently, the following values are the minimum set of
items being used for matching an encounter in the EODS:
•

•
•
•
•
•
•

Beneficiary Demographic
o Health Insurance Claim Number (HICN)
o Name
Date of Service
Place of Service (2 digits)
Type of Service – not submitted on the 837-P, but is derived from data captured
Procedure Code(s) and 4 modifiers

Paid Amount*

* Paid Amount is the amount paid by the MAO or other entity and should be populated in Loop ID-2320,

837-P DME Business Cases

In accordance with 45 CFR 160.103 of the HIPAA, Protected Health Information (PHI) has been removed
from all business cases. As a result, the business cases have been populated with fictitious information
about the Subscriber, MAO and provider(s). The business cases reflect 2012 dates of service.
Although the business cases are provided as examples of possible encounter submissions, MAOs and
other entities must populate valid data in order to successfully pass translator and CEM level editing.
MAOs and other entities should direct questions regarding the contents of the EDS Test Case
Specifications to [email protected].
Note: The business cases identified in the CMS EDS 837-P DME Companion Guide indicate paid amounts
and DTP segments at the line level.
The Adjudication or Payment Date (DTP 573 segment) must follow the paid amount. For example, if the
paid amount is populated at the claim level, the DTP 573 segment must be populated at the claim
level. If the paid amount is populated at the line level, the DTP 573 segment must be populated at the
line level.

Encounter Data DME Processing and Pricing System Edits

After a DME encounter passes translator and CEM level editing and receives an ICN on a 277CA, the
EDFES then transfers the encounter to the Encounter Data DME Processing and Pricing System (EDDPPS)
where editing, processing, pricing, and storage occur. In order to assist MAOs and other entities in
submission of encounter data through the EDDPPS, CMS has provided the current list of the EDDPPS
edits in Table 13.
Note: The edit descriptions listed in Table 13 have been revised to identify a maximum of 41 characters
in order to display a more comprehensive explanation of edits on the MAO-002 Reports.
The EDDPPS edits are organized in four (4) different categories, as provided in Table 13, Column 2. The
EDDPPS edit categories include the following:
•
•
•
•

Validation
Beneficiary
Reference
Duplicate

Table 13, Column 3 identifies two (2) edit dispositions: Informational and Reject. Informational edits
will cause the encounter to be flagged; however, the Informational edit will not cause processing and/or
pricing to cease. Reject edits will cause an encounter to stop processing and/or pricing, and the MAO or
other entity must resubmit the encounter through the EDFES. T The encounter must then pass
translator and CEM level editing prior to transferring the data to the EDDPPS for reprocessing. The
EDDPPS edit description, as found in Table 13, Column 4, is included on the EDPS transaction reports to
provide further information for the MAO or other entity to identify the specific reason for the edit
generated.
If there is no reject edit at the header level and at least one of the lines is accepted, then the encounter
is accepted. If there is no reject edit at the header level, but all lines reject, then the encounter will
reject. If there is a reject edit at the header level, the encounter will reject.
Table 13 reflects only the currently programmed EDDPPS edits. MAOs and other entities should note
that, as testing progresses, it may be determined that the current edits require modifications, additional
edits may be necessary, or edits may be deactivated. MAOs and other entities must always reference
the most recent version of the CMS EDS 837-P DME Companion Guide to determine the current edits in
the EDDPPS.

EDDPPS Edits Enhancements Implementation Dates

As the EDS matures, the EDPS may require enhancements to the EDDPPS editing logic. As these
enhancements occur, CMS will provide the updated information (i.e., disposition changes and activation
or deactivation of an edit). Table 14 provides MAOs and other entities with the implementation dates
for enhancements made to the EDDPPS since the last release of the CMS EDS 837-P DME Companion
Guide.

837 DME Professional Companion Guide Version 22.0/May 2014

EDPS Edits Prevention and Resolution Strategies

In order to assist MAOs and other entities with the prevention of potential errors in their encounter
data submission and with resolution of edits received on the generated MAO-002 reports, CMS has
provided comprehensive strategies and scenarios. CMS has identified the strategies and scenarios in
three (3) phases.
10.2.1 EDPS Edits Prevention and Resolution Strategies – Phase I: Frequently Generated EDDPPS
Edits
Edits previously identified in this section have been deactivated and are no longer required for
submission of DME encounter data. Table 15 has been removed from the CMS EDS 837-P DME
Companion Guide.
10.2.2 EDPS Edits Prevention and Resolution Strategies
Table 16 outlines Phase II for edits mutually generated in all subsystems of the EDPS (Professional,
Institutional, and DME).

Comprehensive Resolution/Prevention
Disposition
00010 From DOS Greater Than TCN
Reject
Encounter must have a DOS prior to submission date.
Date
Scenario: Perfect Health of America submitted an encounter on May 10, 2012 for a knee replacement at Wonderful Hills
Mediplex for DOS May 12, 2012. The encounter was rejected because “from” DOS was after date of encounter submission.
00011 Missing DOS in Header/Line
Reject
Encounter header and line levels must include “from” and
“through” DOS (procedure or service start date).
Scenario: Chloe Pooh was admitted to Regional Port Hospital on October 21, 2012 for a turbinectomy and was released on
October 22, 2012. Regional Port Hospital submitted a claim to Robbins Health for the surgical procedure. Robbins Health
submitted the encounter to the EDS, but did not include the “through” DOS of October 22, 2012.
00012 DOS Prior to 2012
Reject
Encounter must contain 2012 “through” DOS for each line.
Scenario: Ion Health submitted an encounter with DOS from December 2, 2011 through December 28, 2011, for an
inpatient admission at Better Health Hospital. The encounter was rejected because the EDS will only process encounters
that include a 2012 “through” DOS or later.
00025 Through DOS After Receipt Date
Reject
Encounter submitted with a service line “through” DOS that
occurred after the date the encounter was submitted.
Scenario: Leverage Community Health submitted an encounter on August 23, 2012 for a myringotomy performed by Dr.
Earwell. The service line DOS for the procedure was August 29, 2012. The encounter was rejected because the encounter
was submitted to the EDS before the DOS listed on the encounter.

Submitter is attempting to void a previously rejected
Encounter
encounter. Review returned MAO-002 reports to confirm the
rejected encounter.
Scenario: On July 20, 2012, Hero Health Plan submitted an encounter with an invalid HICN. On July 26, 2012, Hero Health
Plan attempted to void the encounter due to the invalid HICN without referencing the MAO-002 report, dated July 25,
2012, that indicated that the encounter was rejected. On August 1, 2012, Hero Health Plan received an MAO-002 report
with edit 00762 for the voided encounter because the original encounter had already been processed and rejected.
00764 Original Must Be Chart Review
Reject
Submitter must ensure that, if the void encounter (frequency
to Void
code ‘8’) is populated with PWK01=’09 and PWK02=’AA’, the
original encounter submission was a chart review encounter
populated with PWK01=’09’ and PWK02=’AA’
Scenario: On January 12, 2013, Paisley Community Health submitted an original encounter for Mr. Jolly Jones to the EDS
and received the accepted ICN of 3029683010582. On February 2, 2013, Paisley Community Health submitted a chart
review encounter to the EDPS to delete a diagnosis code from the original encounter and received the accepted ICN of
5039530285074. In April 2013, Paisley Community Health performed another chart review of Mr. Jones’ medical records
and discovered that the service was never provided. Paisley Community Health submitted a void encounter to the EDS
using the reference ICN of 3029683010582 (the original encounter ICN) and populated PWK01=’09’ and PWK02=’AA’. The
EDS rejected the encounter because the ICN referenced was for the original encounter, not the initial chart review.
00765 Original Must Be Chart Review
Reject
Submitter must ensure that, if the correct/replace encounter
to Adjust
(frequency code ‘7’) is populated with PWK01=’09 and
PWK02=’AA’, the original encounter submission was a chart
review encounter populated with PWK01=’09’ and
PWK02=’AA’. The submitter must also ensure that the ICN
references the initial chart review encounter, not the original
full encounter.
Scenario: Flashback Health performed a chart review for Prosperous Living Medical Center. Flashback Health discovered
two (2) additional diagnosis codes for an encounter previously submitted for Ms. Leanne Liberty. Flashback Health
submitted an initial chart review encounter using the frequency code of ‘7’. The EDS rejected the chart review encounter
submission because initial chart review encounters should contain a frequency code ‘1’.

Submitter has previously adjusted or voided an encounter
Void/Adjusted
and is attempting to adjust the same encounter. Submitter
should review returned MAO-002 reports to confirm
processing of the adjusted encounter prior to resubmission of
the adjustment.
Scenario: On August 20, 2012, Pragmatic Health submitted a correct/replace encounter to correct a CPT code. Pragmatic
Health had not received their MAO-002 report by August 23, 2012 and decided to resubmit the correct/replace encounter.
The MAO-002 report was returned on August 24, 2012 with the correct/replace encounter identified as accepted.
Pragmatic Health received edit 00760 on a subsequent MAO-002 report because the EDPS had already processed the

98315 Linked Chart Review Duplicate
Reject
Linked Chart Review encounters cannot be submitted where
the HICN, Associated ICN and header DOS, diagnosis code(s)
contain the exact same values as another Chart Review
encounter already present within the EODS.
Scenario: Sequoia Health Plan conducted an audit of Timber Lake Family Physicians and discovered an encounter
previously submitted to the EDS contained an unnecessary diagnosis code. On 04/01/14, Sequoia Health Plan submitted a
linked chart review encounter to the EDS containing the associated ICN of the original counter to identify the unnecessary
diagnosis code. On 05/01/14 Sequoia Health Plan inadvertently submitted the exact same linked chart review encounter
to the EDS. The EDS rejected the second submission of the linked chart review encounter because no changes were
detected between the two linked chart review encounters.

DME Supplier vs. Incident to Services Submission

For submission of production data, DME Incident to and DMEPOS Supplier encounter submissions will
be validated according to the NPI and Payer ID only. MAOs and other entities are not required to use
the DMEPOS HCPCS Fee Schedule Job to determine the DME HCPCS jurisdiction.

Submission of Default Data in a Limited Set of Circumstances

MAOs and other entities may submit default data in a limited set of circumstances, as identified and
explained in Table 18. MAOs and other entities cannot submit default data for any circumstances other
than those listed in Table 18. CMS will use this interim approach for the submission of encounter data.
In each circumstance where default information is submitted, MAOs and other entities are required to
indicate in Loop 2300, NTE01=’ADD’, NTE02 = the reason for the use of default information. If there are
questions regarding appropriate submission of default encounter data, MAOs and other entities should
contact CMS for clarification. CMS will provide additional guidance concerning default data, as
necessary.
12.1

Default Data Reason Codes (DDRC)

Loop 2300, NTE02 allows for a maximum of 80 characters and one (1) iteration, which limits the
submission of default data to one (1) message per encounter.
In order to allow the population of multiple default data messages in the NTE02 field, CMS will use a
three (3)-digit default data reason code (DDRC), which will map to the full default data message in the
EDS.
MAOs and other entities may submit multiple DDRCs with the appropriate three (3)-digit DDRC.
Multiple DDRCs will be populated in a stringed sequence with no spaces or separators between each
DDRC (i.e., 036040048). Table 18 provides the CMS approved situations for use of default data, the
default data message, and the default data reason code.

Tier II Testing

CMS developed the Tier II testing environment to ensure that MAOs and other entities have the
opportunity to test a more inclusive sampling of their data. MAOs and other entities that have obtained
end-to-end certification may submit Tier II testing data.
CMS encourages MAOs and other entities to utilize the Tier II testing environment when they have
questions or issues regarding edits received on EDFES Acknowledgement Reports or MAO-002
Encounter Data Processing Status reports; and when they have new submission scenarios that they wish
to test prior to submitting to production.
MAOs and other entities may submit chart review, correct/replace, or void/delete encounters to the
Tier II testing environment only when the encounters are linked to previously submitted and accepted
encounters in the Tier II testing environment.
Encounter files submitted to the Tier II testing environment must comply with the TR3, CMS Edits
Spreadsheet, and the CMS EDS Companion Guides, as well as the following requirements:
•
•
•
•
•
•

Files must be identified using the Authorization Information Qualifier data element “Additional
Data Identification” in the ISA segment (ISA01= 03).
Files must be identified using the Authorization Information data element to identify the “Tier II
indicator” in the ISA segment (ISA02= 8888888888).
Files must be identified as “Test” in the ISA segment (ISA15=T).
Submitters may send multiple Contract IDs per file
Submitters may send multiple files for a Contract ID, as long as each file does not exceed 2,000
encounters per Contract ID
If any Contract ID on a given file exceeds 2,000 encounters during the processing of the file, the
entire file will be returned

As with production encounter data, MAOs and other entities will receive the TA1, 999, and 277CA
Acknowledgement Reports and the MAO-002 Reports.
