The short answer

You don't need a special "Bridge pharmacy." Once your prior authorization is approved, you fill your covered GLP-1 at a participating pharmacy for the flat $50 — and the big national chains (Walgreens, CVS, Walmart, and Sam's Club) have already signed on.

With the Bridge now open, a common question is: "Where do I actually go to get the $50 price?" Good news — because the Bridge is run centrally by Medicare, it isn't tied to your plan's pharmacy network the usual way. Here's how filling works.

One thing has to happen first: approval

Before any pharmacy can ring you up for $50, your prior authorization has to be approved. The order is:

  1. Your doctor submits the prior authorization — to Medicare's central processor, not your Part D plan.
  2. The central processor approves it.
  3. Then you take your prescription to a participating pharmacy and pay $50.

So "where to fill" comes after approval. New to the process? Our paperwork checklist and prior authorization guide walk through getting approved.

Which pharmacies are participating

Ahead of the July 1 launch, the largest national chains have announced they'll fill Bridge prescriptions:

  • Walgreens — at roughly 8,000 pharmacies.
  • CVS — offering the $50 monthly copay for eligible members.
  • Walmart and Sam's Club — at nearly 5,000 pharmacy locations, with pharmacist consultations available.

That covers a large share of the pharmacies most people already use. Independent and regional pharmacies may participate too, but they have to be set up to process Bridge claims through the central processor — so if you use a smaller pharmacy, call ahead and ask whether they can fill a Medicare GLP-1 Bridge prescription. Don't assume; confirm.

How it works at the counter

When you go to fill it:

  • Bring your Medicare card — the pharmacy uses your Medicare number to bill the Bridge's central processor (this is different from a normal Part D fill).
  • You pay the flat $50 for a one-month supply — the same at any dose.
  • The pharmacy submits the claim to the central processor, which pays them the rest.

You don't front the $1,000-plus retail price and wait for reimbursement — the $50 is simply what you owe at the register.

Which drugs you can fill this way

The Bridge covers specific products (full list in which drugs the Bridge covers):

  • Wegovy — pens and tablets
  • Zepbound — the KwikPen
  • Foundayo — tablets

A compounded version isn't covered at the $50 price, even at a participating pharmacy — and the prescription has to be for the exact covered product your prior authorization was approved for.

A few practical notes

  • The program began July 1, 2026 — a pharmacy can only process Bridge claims on or after that date.
  • The $50 is a true flat copay — it doesn't count toward your Part D deductible or the annual out-of-pocket cap.
  • If a pharmacy says it can't process the Bridge, try one of the big chains above, or call 1-800-MEDICARE for help finding one.
  • Mail-order or 90-day supplies: ask your participating pharmacy what's available — terms can vary.

What to do now

  1. Get the prior authorization moving with your doctor — start with our paperwork checklist.
  2. Confirm your usual pharmacy (or a nearby chain) will process Bridge prescriptions.
  3. Not sure you qualify yet? Take the 2-minute eligibility quiz, or read the full Medicare & GLP-1 guide.

Once you're approved, filling is the easy part — show your Medicare card, pay $50, and you're done.
