CWF Edits on MAC (Part A) Claims

activein force · 2026-08-25 – presentas-observed

In order to prevent duplicate payment by the same MAC (Part A), CWF edits by line item on the

MAC (Part A) number, the Medicare Beneficiary Identifier (MBI) number, and the date of

service, the influenza virus procedure codes 90630, 90653, 90654, 90655, 90656, 90657, 90658,

90660, 90661, 90662, 90672, 90673, 90674, 90682, 90685, 90686, 90687, 90688, 90694, or

90756 and the pneumococcal procedure codes 90670, 90671, 90677, or 90732, and the

administration code, G0008 or G0009 .

1. If CWF receives a claim with either HCPCS codes 90630, 90653, 90654, 90655, 90656,

90657, 90658, 90660, 90661, 90662, 90672, 90673, 90674, 90685, 90686, 90687, 90688,

90694, or 90756 and it already has on record a claim with the same MBI number, same

MAC (Part A) number, same date of service, and any one of those HCPCS codes, the

second claim submitted to CWF rejects.

2. If CWF receives a claim with HCPCS codes 90670, 90671, 90677, or 90732 and it

already has on record a claim with the same MBI number, same MAC (Part A) number,

same date of service, and the same HCPCS code, the second claim submitted to CWF

rejects when all four items match.

3. If CWF receives a claim with HCPCS administration codes G0008 or G0009 and it

already has on record a claim with the same MBI number, same MAC (Part A) number,

same date of service, and same procedure code, CWF rejects the second claim submitted

when all four items match.

CWF returns to the MAC (Part A) a reject code “7262” for this edit. MACs (Part A) must deny

the second claim and use the same messages they currently use for the denial of duplicate claims.
