Selected Drug List and Negotiated Prices, also known as Maximum Fair Prices in Statute (ZIP) (September 21, 2026)

Unverified model/legacy excerpt; not proof. AI summary (separate from source): CMS updated its selected-drug and negotiated-price file during the lookback window, showing continued implementation of Medicare negotiated drug prices. This supports partial delivery of broader affordability for Medicare beneficiaries, though it does not establish Matsui as the direct deliverer.

CMS expects GLOBE will reduce out-of-pocket drug costs for people with Medicare and result in savings to Medicare while preserving or enhancing beneficiaries’ quality of care.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): During the lookback window, CMS posted the finalized GLOBE Model page, showing a new mandatory Medicare Part B prescription-drug pricing model expected to reduce beneficiary out-of-pocket costs. This supports continued partial delivery of the affordability goal, but it does not establish Matsui as the direct deliverer.

This final rule implements the Global Benchmark for Efficient Drug Pricing Model (GLOBE Model), a new mandatory Medicare payment model under section 1115A of the Social Security Act.

Fetched verbatim passage. AI summary (separate from source): The Federal Register public-inspection copy confirms CMS finalized the GLOBE Model as a mandatory Medicare payment model, with regulations effective November 30, 2026. This is concrete federal action toward lower Medicare drug costs, but because beneficiary reductions begin later and Matsui’s causal role is not shown, it supports partial rather than full delivery.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): CMS's Medicare Inflation Rebate Program page, last modified October 7, 2026, confirms an ongoing federal mechanism that lowers out-of-pocket costs for some Medicare-covered drugs.

Unverified model/legacy excerpt; not proof. AI summary (separate from source): An official House press release confirms Matsui joined the introduction of legislation directly matching the promise. Because available official bill records still show introduction/referral rather than enactment, this is concrete same-term effort but remains unresolved as delivery.

The record shows Matsui made a concrete same-term effort by introducing the Ensuring Access to Lower-Cost Medicines for Seniors Act of 2026, which would have expanded access to lower-cost drugs for Medicare beneficiaries, but that bill was only introduced and referred, not enacted. Separately, Medicare beneficiaries did retain and continue to benefit from lower drug prices through the existing Medicare negotiation program, but the provided evidence does not show Matsui personally delivered or materially drove that outcome. Under a federal candidate-credit standard, that supports limited credit for advancement toward the promise, not full delivery.

The promised outcome was broadly achieved at the federal level through enacted Medicare prescription drug reforms in the Inflation Reduction Act of 2022, including Medicare drug price negotiation authority, insulin cost caps, vaccine cost-sharing elimination, inflation rebates, and a Part D out-of-pocket cap. Matsui was a sitting House Democrat when the Act passed the House on August 12, 2022 and was signed into law on August 16, 2022, so her vote materially advanced an enacted federal outcome in office. Her 2026 bill to require Part D formularies to include certain lower-cost generics and biosimilars is additional same-term effort, but delivery does not depend on that pending bill.
