When CWF receives a claim from the carrier/AB MAC, it will review Part B outpatient claims history to verify that a duplicate claim has not already been posted.

CWF will edit on the beneficiary HIC number; the date of service; the influenza virus procedure codes 90653, 90654, 90655, 90656, 90657, 90660, 90661, 90662, 90672, 90673, 90685, 90686, 90687, or 90688; the pneumococcal procedure codes 90669, 90670, or 90732; and the administration code G0008 or G0009.

CWF will return a specific reject code for this edit. Contractors must deny the second claim and use the same messages they currently use for the denial of duplicate claims.
