Claims Crossover Disposition and Coordination of Benefits
Agreement Bypass Indicators
(Rev. 4474, Issued; 12-06-19, Effective: 01-04-20, Implementation: 01-06-20)
1. Claims Crossover Disposition Indicators
Effective with the October 2004 systems release, when a COBA trading partner is in
production mode (Test/Production Indicator sent via the COIF submission=P), CWF shall
annotate each processed claim on detailed history in the HIMR with a claims crossover
disposition indicator after it has applied the COBA trading partner’s claims selection
criteria. (See the table below for a listing of the indicators.) In addition, when a COBA
trading partner is in production mode, CWF shall annotate each processed claim with a
10-position COBA ID (5-digit COBA ID preceded by 5 zeroes) to identify the entity to
which the claim was crossed or not crossed, in accordance with the terms of the COBA.
Effective with October 2006, the CWF maintainer updated its data
elements/documentation to capture the revised descriptor for crossover disposition
indicators “E,” as reflected below. In addition, the CWF maintainer shall update its data
elements/documentation to capture the newly added “R,” “S,” “T,” “U,” and “V”
crossover disposition indicators, as reflected in the Claims Crossover Disposition
Indicators table below.
Effective with July 2007, the CWF maintainer updated its data elements/ documentation
to capture the newly added “W,” “X,” and “Y” crossover disposition indicators, as well
as all other changes, reflected in the table directly below.
As reflected in the table below, the CWF maintainer created crossover disposition
indicators “Z” and “AA” to be effective October 1, 2007. The CWF maintainer created a
new “AC” crossover disposition indicator as part of its COBA claims selection
processing effective April 1, 2008.
Effective January 5, 2009, the CWF maintainer created crossover disposition indicators
“AD” and “AE,” as indicated in the table below. The CWF shall utilize the “AD”
indicator when an incoming claim does not meet any of the new adjustment, mass
adjustment, or recovery audit contractor (RAC)-initiated adjustment inclusion criteria, as
specified in §80.8 of this chapter. The CWF shall utilize the “AE” indicator when the
COBA trading partner specifies that it wishes to exclude RAC-initiated adjustments and
CWF does not otherwise exclude the claim for some other reason identified higher within
its crossover exclusion logic hierarchy.
Effective with the July 2009 release, the CWF maintainer shall display all auto-exclude/COBA by-pass events, as detailed below, in association with an adjudicated
claim within the COBA bypass field on page 3 of the HIMR intermediary claim detail
screen and on page 2 of the HIMR Part B and DMEL detail screen.
The CWF shall, in addition, create and display a new “BT” crossover disposition
exclusion indicator on pages 2 and 3 of the HIMR claim detail screens, as appropriate,
effective with July 2009.
Additionally, the CWF maintainer shall create additional fields within claim page 3 of the
HIMR intermediary claim detail screen and page 2 of the Part B and DMEL claim detail
screens to allow for the reporting of crossover disposition indicators in association with
“test” COBA crossover claims. The CWF maintainer shall 1) create additional fields for
displaying “test” crossover disposition indicators within both the eligibility file-based and
claim-based crossover portions of the claim detail screens on HIMR; and 2) display the
“test” crossover disposition indicators so that they mirror all such indicators used for
“production” claims in association with the following four (4) claim versions: 4010A1,
5010, National Council for Prescription Drug Programs (NCPDP)-5.1, and NCPDP-D.0.
IMPORTANT: If the BCRC transmits a COIF that contains a COBA ID within the
range 79000 through 79999 (Medicaid quality project), CWF shall post an “MQ”
disposition indicator in association with the claim instead of the traditional “A” indicator
when it selects the claim for crossover. (NOTE: “MQ” shall designate that Medicare is
transferring the claim for Medicaid quality project purposes only.) CWF shall annotate
claims whose COBA ID is 79000 through 79999 with “MQ” regardless of the claim
version indicator in those instances where it selects the claims for crossover to the BCRC.
CWF shall also annotate the claims with MQ if the COBA ID is marked on the COIF as
being in test (T) or production (P) mode. If CWF excludes from crossover a claim where
the COBA ID equals 79000 through 79999, CWF shall continue to post the crossover
disposition indicator that corresponds to the reason for the exclusion on the appropriate
HIMR claim detail screen.
Effective January 4, 2010, CWF shall apply the newly developed crossover disposition
indicator “AF” (see below) to incoming Part B original and adjustment fully paid claims,
without deductible and co-insurance, when those claims contain denied service lines
where the beneficiary has no liability.
Effective April 6, 2020, CWF shall apply the newly developed crossover disposition
indicator “AG” (see below) to incoming Part B claims that do not meet the Part B
psychotherapy claims inclusion criteria. In addition, CWF shall apply the newly
developed crossover disposition indicator “AH” (see below) to incoming Part B claims
that meet a COBA trading partner’s Part B psychotherapy claims exclusion criteria.

page 2 of the PTBH and DMEH screens and on page 3 of the INPH, OUTH, HHAH, or
HOSH screens. The COBA Bypass Indicators appear in the table directly below.

screens (PTBH or DMEH; INPH, OUTH, HHAH, or HOSH) on HIMR.

Claims Crossover
Bypass Indicator
Definition/Description
BA Claim represents an “Add History” only (action
code 7 on HUOP claims; entry code 9 on HUBC
and HUDC claims). Therefore, the claim is
bypassed and not crossed over.
BB Claim falls into one of two situations: 1) there is no
eligibility record (exception: if HUBC or HUDC
claim has a Medigap claim-based COBA ID); or 2)
the only available eligibility record contains a “Y”
delete indicator. Therefore, the claim is bypassed
and not crossed over.
BC Claim represents an abbreviated encounter record
(TOB=11z; condition code=04 or 69); therefore,
the claim is bypassed and not crossed over.
BD Claim contains a Part B/DME MAC CWF claim
disposition code other than 01, 03, or 05; therefore,
the claim is bypassed and not crossed over.
BE Submission of Notice of Elections [NOEs]
(Hospice—TOB= 8xA through 8xE on HUHC;
CEPP—TOB=11A through 11D on HUIP;
Religious Non-Medical Care—TOB=41A, 41B,
and 41D on HUIP; Medicare Coordinated Care –
TOB=89A and 89B on HUOP). Therefore, the
submission is bypassed and not crossed over.
BF Claim represents an excluded demonstration
(DEMO) project; therefore, the claim is bypassed
and not crossed over.
Claims Crossover
Bypass Indicator
Definition/Description
BG CWF auto-excluded the claim because it was
adjudicated with an “OA” Claim Adjustment
Segment (CAS) Group code for all denied lines or
services.
BN CWF auto-excluded the claim because it contained
a placeholder provider value.
BP Sanctioned provider claim during service dates
indicated; therefore, the claim is bypassed and not
crossed over.
BQ CWF auto-excluded the claim because it contained
only PQRS codes.
BR Submission for Request for Anticipated Payment
[RAP] claims (TOB=322 and 332); therefore, the
submission is bypassed and not crossed over.
BX Non-compliant ICD DX code on claim; therefore,
the claim is by-passed and not crossed over.
BY
A BOI record exists, but there are no active BOI
entries that correspond to the claim's service dates.
Therefore, the claim is bypassed and not crossed
over.
