In order for a claim to be processed as Medicare primary or secondary, the claim must coincide with the information on the common working file (CWF). When a claim is rejected due to conflicting information on CWF, providers should wait until the CWF is updated before submitting any additional claims for that beneficiary. Palmetto GBA is holding claims for up to 75 days for the CWF to be updated.

Claims will be returned to the provider requesting CWF review prior to resubmission. Once the record on CWF is updated, the provider should submit the claim at that time.
