Medicare GLP-1 Bridge: 81 Days Until $50/Month Wegovy and Zepbound (April 2026 Countdown)

Verified April 11, 2026: 81 days until the Medicare GLP-1 Bridge Demonstration Program launches July 1, 2026. The program covers Wegovy and Zepbound at a flat $50/month copay for eligible Medicare Part D beneficiaries — the first time Medicare has ever covered weight-loss medications. Approximately 3.4 million Medicare beneficiaries are expected to qualify in the first six months. Both Novo Nordisk and Eli Lilly have agreed to a net price of $245/month (75-80% below retail list) per a Most-Favored-Nation deal with the Trump administration. If you're Medicare-eligible and have been waiting, now is the time to prepare — here's the 5-step checklist.

Quick answer: use our free Medicare GLP-1 Eligibility Checker to see if you qualify in 60 seconds. Then follow the prep steps below to be ready on launch day.

The 5-Step Prep Checklist (Before July 1, 2026)

Here's what to do in the 81 days between now and July 1 to ensure you can get your first Bridge-covered prescription on launch day:

• •Step 1: Verify your Medicare Part D enrollment. Call 1-800-MEDICARE or log into medicare.gov. The Bridge program runs through Part D, so enrollment is mandatory. If you have Medicare Advantage, check whether your plan includes drug coverage (MAPD) — if not, you may need to enroll in a standalone PDP during open enrollment (October 15 - December 7, 2026) to access the program after the first six months.
• •Step 2: Schedule a baseline medical visit. Your prescriber needs to document your BMI and any weight-related comorbidities (type 2 diabetes, hypertension, cardiovascular disease, sleep apnea, NAFLD, osteoarthritis). This documentation is what supports the prior authorization when the program launches.
• •Step 3: Ask your doctor about prior authorization. The Bridge program uses standard Part D prior auth workflow. Your doctor's office should already be familiar with this — but ask them to flag your chart for the July 1 launch so you're not caught in a backlog.
• •Step 4: Research your preferred medication. Wegovy (semaglutide, 14.9% weight loss per STEP-1) vs Zepbound (tirzepatide, 20.9% weight loss per SURMOUNT-1). Both are covered at $50/month — see our Wegovy vs Zepbound comparison for the head-to-head data.
• •Step 5: Have a plan B ready. If prior auth is delayed or denied, know your backup. NovoCare Wegovy $349/mo and LillyDirect Zepbound $299/mo are cash-pay options that bypass insurance entirely. Compounded options are NOT recommended while you wait — use brand-name only.

Who Qualifies: The Clinical Criteria

The Medicare GLP-1 Bridge uses the same clinical criteria as commercial Wegovy and Zepbound prescribing:

• •Medicare Part D enrolled (Original Medicare + standalone PDP, or Medicare Advantage with MAPD)
• •Age 65+ OR under 65 with disability (SSDI 24+ months) or End-Stage Renal Disease
• •BMI 30 or higher (obesity), OR
• •BMI 27 or higher with at least one weight-related comorbidity: type 2 diabetes, hypertension, dyslipidemia, cardiovascular disease, obstructive sleep apnea, non-alcoholic fatty liver disease, chronic kidney disease, or obesity-related joint problems
• •No contraindications to semaglutide or tirzepatide (medullary thyroid cancer history, MEN 2, severe GI disease, pregnancy)

What Happens After December 31, 2026

The Bridge is a time-limited demonstration — it runs from July 1 through December 31, 2026. After that, the permanent BALANCE Model takes over on January 1, 2027. Here's what changes:

• •Bridge phase (July 1 - December 31, 2026): $50/month flat copay, centralized CMS administration, does NOT count toward your Part D True Out-of-Pocket (TrOOP) cap
• •BALANCE Model phase (January 1, 2027+): Coverage flows through your individual Part D plan. Copays may vary by plan (still capped by the $2,100 Part D annual out-of-pocket max). Plans compete on formulary, prior auth efficiency, and step therapy protocols.
• •Transition risk: If your Part D plan decides to place Wegovy or Zepbound on a higher tier in 2027, your copay could increase. Watch your 2027 Annual Notice of Change (ANOC) in October 2026.

The Most-Favored-Nation Deal: Why $245 Matters

The $50/month copay is only possible because of the December 2025 Most-Favored-Nation (MFN) deal between the Trump administration and both drug manufacturers. Under MFN, Novo Nordisk and Eli Lilly agreed to charge Medicare a net price of $245/month for both Wegovy and Zepbound — 75-80% below the retail list price of $1,349 (Wegovy) and $1,086 (Zepbound).

The math: $245/month net → you pay $50 → Medicare pays the remaining $195. CMS estimates the program will cost approximately $2.1 billion in the first six months, covering roughly 3.4 million beneficiaries at an average of 4 months of treatment per patient (accounting for titration periods where patients aren't yet on the therapeutic dose).

This is unprecedented — it's the first time Medicare has negotiated a single-drug discount of this magnitude outside of the IRA Part D negotiation process. Both manufacturers agreed because (a) 3.4 million new patients is massive volume and (b) the alternative was being excluded from Medicare coverage entirely.

What to Watch Next

• •May 2026: CMS is expected to publish the final Bridge program operational manual, including the exact prior authorization template and provider enrollment requirements
• •June 2026: Part D plans finalize their Bridge integration. Watch for announcements from major PBMs (CVS Caremark, Express Scripts, OptumRx, Humana)
• •June 15-30, 2026: Pre-launch enrollment window opens for the first patient cohort. If your prior auth is ready, you'll be able to submit as early as June 15
• •July 1, 2026: LAUNCH DAY. First prescriptions filled. Expect pharmacy stock shortages in the first 2-4 weeks as demand ramps
• •October 15 - December 7, 2026: Medicare Open Enrollment. Time to switch plans if your current one isn't supporting the Bridge well
• •January 1, 2027: BALANCE Model takes over. Bridge ends
