Where Things Stand Right Now

The Medicare GLP-1 Bridge is a CMS demonstration that lets eligible Part D members get certain GLP-1 weight-loss medications for a flat $50 per month. It runs from July 1, 2026 through December 31, 2027.

As of today, the Bridge has not opened yet — your doctor cannot submit a Bridge prior authorization before July 1, 2026. But here is the key thing: the people who prepare in advance will be first in line when it opens. Doctor appointments fill up, documentation takes time to gather, and the first weeks of any new Medicare program are the busiest. This guide walks you through exactly what to do now, and exactly what happens once the Bridge goes live.

What the Bridge Actually Gives You

For eligible members, the Bridge covers these weight-management GLP-1 medications for a flat $50 per month, no matter the dose:

  • Wegovy (injection and tablet)
  • Zepbound (KwikPen)
  • Foundayo

That $50 replaces the $1,000–$1,400 these drugs otherwise cost. It does not count toward your Part D deductible or your annual out-of-pocket cap. For the full rules, see our Medicare & GLP-1 coverage guide.

Step 1 — Confirm You Have the Right Kind of Medicare

To use the Bridge, you need prescription drug coverage:

  • A standalone Part D plan, or
  • A Medicare Advantage plan that includes drug coverage (an MA-PD plan)

Original Medicare with no drug plan cannot access the Bridge. The good news: CMS runs the Bridge centrally, so it works regardless of which Part D or MA-PD plan you have — your plan does not need to opt in. If you are not sure which kind of plan you have, check your insurance card or call the number on the back.

Step 2 — Figure Out Your BMI Tier

The Bridge uses three eligibility tiers based on body mass index (BMI), plus a related health condition at the lower BMIs:

  • Tier 1 — BMI 35 or higher. No additional condition required.
  • Tier 2 — BMI 30 or higher with heart failure (preserved ejection fraction), high blood pressure not controlled on two or more medications, or chronic kidney disease (stage 3a or higher).
  • Tier 3 — BMI 27 or higher with prediabetes, a prior heart attack, a prior stroke, or symptomatic peripheral artery disease.

Here is the good news: you don't have to figure any of this out on your own. Our free 2-minute eligibility quiz asks a few simple questions — your height and weight, your type of Medicare plan, and your health conditions — and then tells you, in plain English, which tier you likely fall under and whether you qualify. It answers every one of these eligibility questions for you, so you walk into your doctor's visit already knowing where you stand instead of guessing. If you do just one thing today, take the eligibility quiz first.

Step 3 — Gather Your Documentation Now

This is the single most useful thing you can do during the wait. Your doctor needs solid documentation to submit a clean prior authorization. Pull together:

  • Your weight history — recent measurements, ideally from a medical scale, and any record of past weight-loss attempts.
  • Records of your qualifying condition (for Tier 2 or 3) — recent labs, blood pressure readings, cardiology or kidney reports, a prediabetes A1C, etc.
  • A current list of your medications — especially blood pressure medications, which matter for Tier 2.
  • Your Part D or MA-PD plan information.

Having this ready means your doctor can submit on day one instead of sending you back for more paperwork.

Step 4 — Find a Provider and Book Early

You do not need to wait until July to see your doctor. If you already have a primary care doctor, internist, endocrinologist, or nurse practitioner you trust, book an appointment now for late June or early July so they can review your documentation and be ready to submit the moment the Bridge opens.

Don't have a GLP-1 prescriber yet? Start with our Provider Directory — it lists Medicare-friendly GLP-1 prescribers across the country, searchable by state, city, or ZIP code, so you can find someone near you before you book. Many listings are flagged as confirmed GLP-1 prescribers based on public Medicare data.

When you call to schedule, ask one specific question: "Has this provider submitted GLP-1 prior authorizations under Medicare before?" Some practices are already up to speed; others are still learning the process — and an experienced one will make your enrollment smoother.

Step 5 — Your Doctor Submits the Prior Authorization (On or After July 1)

Here is the part that surprises people: the Bridge prior authorization does not go to your Part D plan. It goes directly to CMS, through a central processor run by Humana via the LI NET program. CMS reviews it and approves, denies, or asks for more information — usually within a few days.

This is different from how a normal Part D drug works, so it is worth knowing in advance. For the full step-by-step on the prior authorization itself, see our detailed guide: GLP-1 Prior Authorization on Medicare.

Step 6 — Fill at a Participating Pharmacy

Once CMS approves, your prescription goes to a participating pharmacy. Major chains (Walgreens, CVS, Walmart, Costco) generally participate. The pharmacy first runs it through your regular Part D plan, where it will show as not covered — that is expected — then processes it through the Bridge for the $50 copay. If a pharmacist is unfamiliar with the program in the early weeks, ask them to run it through the CMS Bridge via Humana LI NET.

Your Pre-Launch Checklist

Before July 1, you can already:

  1. Confirm you have a Part D or MA-PD plan.
  2. Take the eligibility quiz to find your likely tier.
  3. Gather your weight history, condition records, and medication list.
  4. Find a Medicare-friendly GLP-1 prescriber in our Provider Directory.
  5. Book that doctor visit for late June or early July so they can submit on day one.

Do those five things and you will be ready to move the moment the Bridge opens — instead of starting from scratch in the busiest weeks of the program.

A Note on Timing and Accuracy

Bridge rules come from CMS and can be updated before launch. Always verify the current criteria at CMS.gov or with your plan before making decisions about your care. This guide is educational and is not a substitute for advice from your doctor or your plan.
