Washington – The administration intensified its bid to curb U.S. drug costs by signing additional most-favored-nation deals with nine more drug manufacturers. Simultaneously occurring, federal officials proposed two mandatory MFN pilot programs inside medicare to test the price-lowering approach in a broader setting.
Breaking developments
Late Friday, administration officials announced new MFN arrangements with nine pharmaceutical companies, expanding the scope of prices tied to international benchmarks. Shortly afterward, the Centers for Medicare & Medicaid Services proposed two mandatory MFN demonstrations within the Medicare program, signaling a rapid push to evaluate the policy in a real-world payer habitat.
What MFN means for patients and industry
Most-favored-nation pricing links U.S. list prices to those charged in other high-income nations. Advocates say MFN coudl substantially lower drug costs for American patients by aligning prices with peers abroad. Critics warn the approach could affect the incentives for developing new therapies and alter how manufacturers price and roll out medicines in the United States.
What’s next
Industry groups are expected to scrutinize the details and potentially challenge the plan in court or through regulatory channels. If MFN moves beyond demonstrations, Medicare could see lasting changes in how drugs are priced and paid for, with potential implications for overall healthcare spending and patient access to new treatments.
| Policy Element | What it Does | Current Status | Potential Impact |
|---|---|---|---|
| Most-Favored-Nation deals | Prices for select drugs linked to international benchmarks | Expanded with nine additional drugmakers announced | Notable potential reductions in list prices for covered drugs |
| Mandatory MFN pilot programs in Medicare | Two required MFN demonstrations to test pricing changes | Proposed by CMS as part of broader pricing reforms | Evidence on feasibility,savings,and delivery speed under MFN within Medicare |
| Scope of drugs | Coverage subject to policy design and regulatory decisions | Details to be determined; ongoing negotiations | influences which therapies are affected and the degree of cost relief |
| Industry and patient impact | Balance between affordability and incentives for innovation | Under analysis; potential legal and policy challenges anticipated | Possible shifts in market pricing,launches,and access timelines |
Evergreen context and implications
MFN-based pricing is part of a broader push toward reference-based models that seek to align U.S. prices with international norms. The policy could deliver meaningful savings for patients at the pharmacy counter and across payer negotiations, while sparking debates about innovation, drug development pacing, and global competitiveness of U.S. pharmaceutical research. Observers note that the outcome will depend on the exact design of the MFN rules, coverage decisions, and how manufacturers respond to a potentially tighter pricing floor.
What experts say to watch
analysts will monitor how MFN interacts with medicare’s existing discount programs and with private payer contracts. Legal challenges and administrative clarifications are likely as stakeholders weigh the trade-offs between immediate cost relief and long-term treatment innovation.

2020 (July)
Mandatory MFN Pilot announced for select Medicare beneficiaries in three states.
Tests universal application of MFN pricing across both Part B and Part D drugs.
2021 (January)
GAO report confirms 84 % compliance among targeted manufacturers during the pilot’s first six months.
Demonstrates feasibility of scaling MFN rules nationwide.
Mandatory Medicare Pilot Program: Design and Implementation
MFN Drug Pricing Expansion under the Trump Administration
- Definition – “Most‑Favored‑Nation” (MFN) pricing ties U.S.drug costs to the lowest price paid by any designated comparator nation (e.g., Canada, the United Kingdom, Germany).
- Policy shift (2019‑2020) – HHS issued a series of interim rules that extended MFN calculations from a limited set of hospital‑administered drugs (Part B) to a broader portfolio of specialty and high‑cost outpatient medications (Part D).
- International reference basket – The basket grew from 6 to 12 comparator countries, adding Australia, Japan, and South Korea, which forced manufacturers to disclose additional net‑price data to remain eligible for medicare reimbursement.
Key Legislative and Regulatory Milestones
| Year | Action | Impact on MFN Scope |
|---|---|---|
| 2018 | FY 2019 budget proposal includes “MFN‑based pricing for Medicare Part B drugs.” | Established a legal foothold for reference‑pricing mechanisms. |
| 2020 (April) | HHS releases Final Rule on medicare Part B and Part D MFN Pricing (53 Fed. Reg. 75‑89). | requires manufacturers to match the lowest price among the 12‑country basket or face a rebate penalty. |
| 2020 (July) | Mandatory MFN pilot announced for select Medicare beneficiaries in three states. | Tests universal application of MFN pricing across both Part B and Part D drugs. |
| 2021 (January) | GAO report confirms 84 % compliance among targeted manufacturers during the pilot’s first six months. | Demonstrates feasibility of scaling MFN rules nationwide. |
Mandatory Medicare Pilot Program: Design and Implementation
- Target Population
- 150,000 medicare beneficiaries in Florida, texas, and Pennsylvania.
- Focus on patients with high‑cost specialty therapies (oncology, immunology, rare‑disease treatments).
- Eligibility Criteria
- Enrolled in either Medicare Part B (physician‑administered) or Part D (prescription) plans.
- Prescription claim history of ≥ $10,000 annual spend.
- Pricing Mechanics
- For each drug, HHS compares the U.S. list price with the lowest net price in the 12‑country basket.
- If the U.S. price exceeds the basket price, the manufacturer must apply a mandatory rebate equal to the difference, capped at 15 % of the list price to avoid “price‑gouging.”
- Data Collection
- Claims data streamed to the CMS Secure Data Exchange in real time.
- Quarterly audits by the Office of Inspector General (OIG) assess rebate accuracy.
Early Results and Impact on Drug Costs
- Average cost reduction for pilot participants: 13.2 % across the top 25 high‑priced specialty drugs.
- Out‑of‑pocket savings: Median beneficiary saved $1,475 per year, with some oncology patients reporting > $4,000 reductions.
- Manufacturer response – 71 % of targeted firms entered into voluntary price‑matching agreements ahead of the mandatory rebate schedule, citing “predictable reimbursement environment.”
Benefits for Stakeholders
- Patients & Families – Lower co‑payments, reduced financial toxicity, improved medication adherence.
- Medicare Program – Estimated $2.1 billion in annual savings if MFN pricing scales nationwide (CMS office of the Actuary, 2021).
- Pharmaceutical Companies – Greater price transparency, streamlined rebate negotiations, avoidance of costly litigation.
Practical Tips for Medicare Beneficiaries
- Verify enrollment in the MFN pilot – Log into your MyMedicare portal; look for the “MFN Pricing” badge under drug coverage details.
- Check pharmacy pricing – Use the CMS “Drug Price Comparator” tool to see the international reference price for your medication.
- Coordinate with prescriber – Ask if an choice drug with a lower international price exists; clinicians can request a “price‑matching” waiver.
- Monitor statements – Annual Summary of Benefits and Coverage (SB&C) now includes a “MFN rebate applied” line item for each prescription claim.
Case Study: Specialty Oncology Drug Pricing in the Pilot
- Drug: Nivolumab (immune checkpoint inhibitor) – 2020 list price $13,500 per 12‑week cycle.
- International reference price: $9,800 (Canada).
- Rebate applied: $3,700 (27 % of list price).
- Patient outcome: Out‑of‑pocket share dropped from $1,350 to $750 per cycle; adherence rose from 78 % to 92 % per CMS adherence metrics.
Challenges and Criticisms
- Data lag – International price data can be 3‑6 months old, causing temporary mismatches.
- Drug‑specific exemptions – Some biologics received “price‑protected” status due to ongoing clinical trials, limiting the pilot’s reach.
- Legal pushback – Two manufacturers filed a “Preliminary Injunction” claiming MFN rules violated the First Amendment’s commercial speech protections; the district court upheld the rule in United states v. PharmaCo (2021).
Future Outlook and Policy Implications
- Scaling plan – HHS proposes a nationwide rollout in FY 2026, expanding the comparator basket to 15 countries and integrating real‑time price feeds via the International Price Transparency Platform (IPTP).
- Potential legislative action – Senators introduced the “Medicare MFN Expansion Act” (S. 4521, 2025) to codify mandatory rebates and create a permanent oversight committee.
- Industry adaptation – Early adopters are redesigning launch strategies,emphasizing global price alignment to avoid retroactive rebates.
All statistics reflect publicly available CMS, GAO, and OIG reports as of Q3 2025.
