The Medicare Part D Coverage Gap Discount Program Q4 2018 invoice payments are due by Monday, March 11, 2019

Manufacturers and Part D Sponsors are required to pay all Q4 2018 invoiced amounts by Monday, March 11, 2019. All CGDP payments must be made via the Portal per the Direct Payment Process. We encourage you to use the Portal future date invoice payments functionality to assure that your payments are made on-time. To make sure your payment transaction is completed on time, it is not recommended to wait until the last day before the payment deadline to make your payment.

The Centers for Medicare & Medicaid Services (CMS) shall assess a Civil Money Penalty (CMP) on a manufacturer that fails to pay the amounts invoiced within the required timeframe. Invoice payments are required to be made in full by the 38th calendar day after receipt of the invoice report. This means that the payment deadline may be a weekend or holiday date. The CMP is equal to the sum of the applicable discount payments that the manufacturer has failed to provide plus 25%.

If you would like assistance with scheduling invoice payments for a future date or have any questions about invoice payments, please contact the TPA by phone at 1-877-534-2772, option 1 or by email at
