Contractors shall pay for IBT CVD, G0446 only when services are provided at the following POS:

Claims not submitted with one of the POS codes above will be denied.

The following messages shall be used when Medicare contractors deny professional claims for incorrect POS:

Remittance Advice Remark Code (RARC) N428: “Not covered when performed in this place of service.”

Medicare Summary Notice (MSN) 21.25: “This service was denied because Medicare only covers this service in certain settings.”

Spanish Version: El servicio fue denegado porque Medicare solamente lo cubre en ciertas situaciones."

Group Code PR (Patient Responsibility) assigning financial liability to the beneficiary, if a claim is received with a GA modifier indicating a signed ABN is on file.

Group Code CO (Contractual Obligation) assigning financial liability to the provider, if a claim is received with a GZ modifier indicating no signed ABN is on file.
