Part D Plans Get Ready for Potentially ‘Messy’ Rollout of M3P Program

For the first time ever, Medicare Part D beneficiaries in 2025 will have the opportunity to spread their prescription drug expenses over the course of the plan year. While Part D sponsors must offer the option to enrollees effective Jan. 1, 2025, plans face multiple considerations and tasks prior to then. One of their most immediate concerns, industry experts say, is factoring in potential administrative costs and/or financial losses associated with the new Medicare Prescription Payment Plan (M3P, as many are calling it) into bids due next month.

Created under the Inflation Reduction Act, the M3P requires stand-alone Prescription Drug Plans and Medicare Advantage Prescription Drug plans to give enrollees the option to pay out-of-pocket prescription drug costs in the form of capped monthly payments versus paying the full amount at the pharmacy. Program participants will pay $0 at the pharmacy but receive a monthly bill from their Part D carrier, which must reimburse the pharmacies in full.
