# US Medicare drug pricing reform implementation > Live situation record from CLSTR: https://clstr.news/situations/us-medicare-drug-pricing-reform-implementation > Updated: 2026-08-10T21:03:03.000Z. Sources: 3. Developments: 2. The implementation of drug pricing reforms under the Inflation Reduction Act has entered a phase of operational adjustment and regulatory expansion. Following the January 2026 launch of the Medicare Maximum Fair Price (MFP) program, health systems and pharmacies have faced administrative challenges regarding post-payment adjustments and dispute tracking. Concurrently, bipartisan legislative efforts in the House have targeted pharmacy benefit managers (PBMs) to ensure fair reimbursement and transparency. Building on these developments, the Centers for Medicare & Medicaid Services (CMS) has proposed a rule to codify the Medicare Drug Price Negotiation Program (MDPNP). This proposal seeks to establish policies for 2029 and beyond, potentially expanding the program to include nearly 60 drugs in future negotiation cycles. While the program is currently in its third cycle negotiating prices for 15 drugs, the new regulatory framework aims to provide long-term certainty for manufacturers while managing high-expenditure, single-source drugs. ## Timeline ### 2026-08-10: CMS proposes codifying Medicare drug price negotiation program CMS has proposed a rule to codify the Medicare Drug Price Negotiation Program, expanding eligibility to nearly 60 drugs starting in 2029. 3 sources. https://clstr.news/cluster/cms-proposes-codifying-medicare-drug-price-negotiation-program ### 2026-07-23: US Medicare MFP rollout and bipartisan PBM bill reshape drug pricing Medicare’s new Maximum Fair Price program strains provider operations, while bipartisan legislation targets PBM practices to lower drug costs and boost transparency. 2 sources. https://clstr.news/cluster/us-medicare-mfp-rollout-and-bipartisan-pbm-bill-reshape-drug-pricing --- Cite as: US Medicare drug pricing reform implementation.
