How are invoice payments made in the Coverage Gap Discount Program?


You cannot pay your invoices via any other method other than through the CGDP Portal. This process is designed to perform ACH transactions per National Automated Clearing House Association (Nacha) rules and guidelines. For each invoice line item or group of lines items submitted for payment initiation, the TPA instructs PNC Bank to issue an aggregated debit to the payer’s account on the TPA’s behalf. Once the debits have successfully completed, individual payments are transferred to the selected payee’s accounts.

For companies who have a debit block enabled, they will need to inform their bank to allow debits for a specific Company ID, which will be supplied by the TPA. In this process, the TPA is acting as the Third-Party Sender and PNC Bank is acting as the Originating Depository Financial Institution (ODFI) per Nacha rules and guidelines.
