Allowing the Common Working File (CWF) to accept both Medicare Secondary Payer (MSP) and Non-MSP Lines on MSP Claims and MSP Adjustment Claims
This change request directs CWF to accept both MSP and non-MSP lines on the same claim and not to send the 5414 error code when MSP and non-MSP lines appear on the same claim. This CR also directs CWF to not send the 5410 error code when deductible is due, but to send the AA (deductible rejects) 8018 and 8019 for the Part B and the DMERC Contractors.
