Article update — Medicare GLP-1 Prescriptions by State. Corrected the national-versus-state claim totals in Article structured data; clarified relative versus absolute state variation, ranking labels, rounding, and current Medicare GLP-1 Bridge context. Confirmed 2024 remains the latest CMS annual Geography and Drug distribution. The 2019–2024 data and dataset v1.1.0 are unchanged.
Article update — GLP-1 Patent Expiration Tracker. Checked the September 14 FDA Paragraph IV PDF, corrected strength-specific Mounjaro and Zepbound rows and the meaning of its patent-date field, added Health Canada’s September 16 Sandoz approval-status record, and clarified historical price observations, adjusted sales, and the Trulicity anniversary. Dataset v2.0 is unchanged; individual Orange Book patent associations, litigation outcomes, and current retail prices were not all newly verified.
Correction — Medicare GLP-1 Bridge Program guide (/guides/medicare-glp-1-bridge-program/). An earlier version of the step-by-step process section incorrectly showed the Bridge prior authorization being submitted to the beneficiary’s Part D plan and the beneficiary paying the plan’s copay. The Bridge uses a pharmacy-first process: the prescriber sends the prescription to the pharmacy; the pharmacy submits the claim to the CMS central processor; the denied Bridge claim then triggers the PA request, which the prescriber submits electronically or by fax. A Part D denial is not required. The page has also been updated to: (1) add a hard-exclusion screen (CY2026 Part D GLP-1 history, T2D, moderate-to-severe OSA, noncirrhotic MASH) before the BMI eligibility section; (2) correct the BMI 30–34.99 qualifying-conditions list to include prediabetes, prior MI, prior stroke, and symptomatic PAD; (3) remove stale pre-launch language; (4) remove speculative BALANCE pricing and drug-list details; and (5) update all dates to July 10, 2026.
