SPAP ADAP Resources


NCPDP, CMS, and the CMS Transaction Facilitator are continually enhancing processes to identify claims for TrOOP eligible State Pharmaceutical Assistance Programs (SPAPs) and AIDS Drug Assistance Programs (ADAPs).  Their goals are to help increase the likelihood that SPAP and ADAP claims are appropriately applied to the member’s TrOOP and that the appropriate entity is refunded or invoiced in the event of a copay/coinsurance adjustment.
