Payment Due Date Reminder! 

The Medicare Part D Manufacturer Discount Program (MDP) Q1 2025 invoice payments are due by Monday, 06/09/2025. 

Manufacturers and Part D Sponsors are required to pay all Q1 2025 invoiced amounts by Monday, 06/09/2025

All MDP payments must be made via the Manufacturer Payment Portal (MPP). The Third-Party Administrator (TPA) encourages you to use the MPP future date invoice payments functionality to assure that payments are on-time. To make sure payment transactions are completed timely, it is not recommended to wait until the last day before the payment deadline to make a payment. Invoice payments are required to be paid in full by the 38th calendar day after receipt of the invoice report. This may result in the payment deadline being a weekend or holiday date. 

The Centers for Medicare & Medicaid Services (CMS) shall assess a Civil Monetary Penalty (CMP) on a manufacturer that fails to pay the amounts invoiced within the required time limit. The CMP is equal to the sum of the applicable discount payments that the manufacturer has failed to provide plus 25%. 

For more information on invoices, including how to schedule invoice payments for a future date, please refer to the MDP User Guide

For additional questions, please contact the TPA by phone at 1-877-534-2772, option 1 or by email at tpaoperations@tpadministrator.com.

Thank you for your prompt attention to this matter.
