Does my doctor file the prior authorization before or after the pharmacy submits the claim?

After. The pharmacy must submit the initial claim to the Bridge central processor first (BIN 028918 / PCN MEDDGLP1BR). That triggers the Bridge to send the PA request form to your doctor. If your doctor files the PA before the pharmacy claim is submitted, it will not work.

Are Zepbound vials covered under the Medicare GLP-1 Bridge?

No. Only the Zepbound KwikPen formulation is covered. Single-dose vials and single-dose pens are specifically excluded by CMS.

Medicare GLP-1 Bridge Program: What You Need to Know (2026)

Q: I have sleep apnea. Does that help me qualify at a lower BMI?

No. Moderate-to-severe sleep apnea is a disqualifying condition for the Bridge program. Patients with that diagnosis must request GLP-1 coverage through their Part D plan instead.

Q: Does Medicare cover Wegovy?

Yes, starting July 1, 2026, Medicare covers Wegovy through the GLP-1 Bridge Program for eligible beneficiaries at a flat $50/month. Both injectable and oral tablet formulations are covered. This operates outside standard Part D coverage.

Q: Does Medicare cover Zepbound?

Yes, the Zepbound KwikPen formulation is covered under the Medicare GLP-1 Bridge starting July 1, 2026, at $50/month. Zepbound vials and single-dose pens are not covered.

The Medicare GLP Bridge Program is a separate CMS pilot program covering Wegovy, Zepbound, and Foundayo for weight loss at a flat $50 a month. The billing works differently from regular Part D, and there is a prior authorization step in the process. This guide walks through how the program works, who qualifies, and what the $50 actually gets you.

Quick Answer

The Medicare GLP Bridge Program is a separate CMS pilot program (not a Part D benefit) that covers Foundayo®, Wegovy®, and Zepbound® (KwikPen® only) for weight loss at a flat $50/month. Your doctor files a prior authorization after the pharmacy submits the initial claim. Decisions come within 72 hours. It works with any eligible MA or PDP plan. It does not count toward your Part D out-of-pocket cap (TrOOP).

Counts Toward TrOOP?

Separate from Part D

What the GLP Bridge Program Does Not Cover

The Bridge looks like a drug benefit, but it operates completely outside of Part D. Before you get excited about the $50 price, understand what that $50 does and does not do for your overall drug costs.

No TrOOP credit — outside the $2,100 cap

Your $50/month does not count toward your Part D True Out-of-Pocket (TrOOP) total or the $2,100 out-of-pocket cap (increasing to $2,400 in 2027). It has zero effect on your other drug costs.

Separate billing system — not your Part D plan

The Bridge uses its own billing system, a separate CMS central processor (Humana). Claims do not run through your normal Part D plan.

Part D deductible does not apply

Bridge claims are outside Part D entirely. Your Part D deductible does not apply to these drug fills.

No secondary payer stacking allowed

You cannot stack a secondary payer on top of a Bridge claim. COB is not permitted under the Bridge program.

Weight loss only — diabetes and sleep apnea disqualify

The Bridge covers weight loss only. Patients with type 2 diabetes, moderate-to-severe sleep apnea, or MASH must request GLP-1 coverage through their Part D plan instead.

Not every GLP-1 drug is covered

Only Foundayo®, Wegovy® (injectable and oral tablets), and Zepbound® KwikPen® are covered. Zepbound vials and single-dose pens are not covered. Ozempic is not included.

The $50 Does Not Help With Your Other Drug Costs

Budget for the Bridge as a standalone monthly expense. It sits completely outside your Part D plan, which means the $50 you pay does not push you toward your $2,100 annual out-of-pocket cap (increasing to $2,400 in 2027). Your other prescriptions are unaffected.

What the Bridge Actually Provides

Despite those limits, the Bridge delivers real value for the right patient:

Three drugs covered for weight loss: Foundayo® (oral pill), Wegovy® (injection or oral tablet), and Zepbound® KwikPen® — all at a flat $50 a month, no matter the dose
Works with any Medicare Advantage or standalone Part D plan. You don't need a special plan or a Humana plan to use it
Fills can be picked up at pharmacies across the country through the national billing processor
Your doctor gets a decision within 72 hours — much faster than a typical Part D prior authorization
Once you're approved, your refills go through automatically. No new PA needed each month
Your copay stays at $50 no matter which dose your doctor prescribes

You Do Not Need to Switch Your Plan

Whatever Medicare plan you're on stays the same. The Bridge routes all claims through Humana as the national central processor — not because you need a Humana plan, but because CMS selected Humana to run the billing infrastructure for every Bridge claim in the country.

Who Is Eligible for the GLP Bridge Program?

All of these need to be true before the PA is filed:

You have Medicare with Part D drug coverage — either a Medicare Advantage plan with drug coverage (MA-PD) or a standalone Part D plan (PDP)
You are 18 or older
Your Part D plan is not already paying for a GLP-1 drug for you
You do not have type 2 diabetes, moderate-to-severe sleep apnea, or MASH (a type of fatty liver disease) — these conditions disqualify you from the Bridge
Your doctor is prescribing the drug for weight loss, not for another condition
Your BMI meets one of the three tiers described below

The Three BMI Tiers: Which One Are You?

CMS uses three different BMI thresholds. Each tier has different qualifying health conditions. Read carefully: the conditions allowed at each tier are specific.

Tier 1: BMI 35 or Higher

No additional condition needed. If your BMI is 35 or above, you meet the clinical criteria on BMI alone. Your doctor documents your height and weight. That's it.

Tier 2: BMI 30–34.9 + One of These Conditions

Your BMI is 30 or above AND you have been diagnosed with at least one of the following:

Heart failure with preserved ejection fraction (HFpEF)
Uncontrolled hypertension: blood pressure above 140/90 mmHg that is not adequately controlled with antihypertensive medication
Chronic kidney disease (CKD) stage 3a or higher

Tier 3: BMI 27–29.9 + One of These Conditions

Your BMI is 27 or above AND you have been diagnosed with at least one of the following:

Pre-diabetes
Previous heart attack (myocardial infarction)
Previous stroke
Symptomatic peripheral artery disease (PAD)

Sleep Apnea Does Not Qualify — It Disqualifies

Sleep apnea is one of the most commonly misunderstood conditions for this program. Moderate-to-severe sleep apnea actually disqualifies you from the Bridge, those patients must request GLP-1 coverage through their Part D plan instead. High cholesterol is also not a qualifying condition under any BMI tier.

GLP Bridge Program BMI Eligibility Tiers

Three different pathways, each tier has specific qualifying conditions

Who Cannot Use the Bridge

You cannot use the Bridge if any of these apply to you:

You have type 2 diabetes (must go through Part D)

You have moderate-to-severe sleep apnea (must go through Part D)

You have MASH / fatty liver disease (must go through Part D)

You are already receiving a GLP-1 drug through your Part D plan

You receive Medicare Extra Help / Low Income Subsidy (LIS)

You are under 18 years old

You are enrolled in a PFFS, PACE, section 1876 cost, fallback, or religious fraternal benefit plan (unless also in a standalone PDP)

Does Medicare Cover Wegovy in 2026?

Yes — starting July 1, 2026, Medicare covers Wegovy (both injectable and oral tablet formulations) through the GLP-1 Bridge Program for eligible beneficiaries. Your cost is a flat $50 per month. This is not Part D coverage — it runs through a separate CMS central processor. You must meet the BMI eligibility criteria and not have a disqualifying condition (type 2 diabetes, moderate-to-severe sleep apnea, or MASH) to qualify.

Does Medicare Cover Zepbound in 2026?

Yes — the Zepbound KwikPen formulation is covered under the Medicare GLP-1 Bridge Program starting July 1, 2026, at a flat $50/month. Important: only the KwikPen formulation is covered. Zepbound single-dose vials and single-dose pens are specifically excluded by CMS. If your doctor has prescribed vials, ask about switching to the KwikPen before filing the prior authorization.

Your Doctor's Role vs. Your Role

Your Doctor (Prescriber)

Sends the prescription to the pharmacy with an obesity diagnosis code (E66 family) and the note "SEND TO BRIDGE FOR WEIGHT MANAGEMENT." Then waits for the Bridge central processor to send the PA request form — usually within 24–72 hours — and completes it.

You (The Patient)

You do not fill out the PA form. Your job is to schedule the appointment, confirm your BMI is documented in your chart, and make sure your pharmacy knows to route the claim to the Bridge billing codes. Then wait for the 72-hour decision.

The GLP Bridge Program Prior Authorization Process: Step by Step

The order matters here. The pharmacy submits a claim first — that's what triggers the PA request to the doctor. Most patients and providers expect it to work the other way around.

Doctor Visit & Prescription

Your doctor checks your BMI and qualifying conditions, decides you're eligible, and sends the prescription to the pharmacy. They include an E66 obesity code and write "SEND TO BRIDGE FOR WEIGHT MANAGEMENT" in the note field.

Pharmacy Submits Claim to Bridge

The pharmacy routes the claim to the Bridge central processor using BIN 028918 / PCN MEDDGLP1BR with your MBI as the Cardholder ID. They should expect a "75 – Prior Authorization Required" response. This is normal, not a rejection.

Bridge Sends PA Form to Doctor

CMS verifies your eligibility. If you qualify, the Bridge sends the PA request form to your doctor via electronic prior authorization (ePA) or fax, usually within 24–72 hours. Your doctor should not file the PA before receiving this request — the form comes from the Bridge, not the other way around.

Doctor Completes the PA Form

Your doctor fills out the form, attesting that the information is true under penalty of perjury. CMS may independently check Medicare data to verify. The completed form goes back via ePA or fax.

Decision Within 72 Hours

CMS sends the approval or denial to your doctor (via ePA/fax) and mails a written notice to you. If approved, you can pick up your prescription. If denied, you may resubmit the PA for re-review.

You Pay $50 at the Pharmacy

The pharmacy resubmits the claim to the Bridge central processor with your PA on file. Your cost: $50 flat. Only 28-day or 30-day fills are covered. Subsequent refills don't require a new PA unless you switch drugs.

The Pharmacy Submits the Claim First — Then the Doctor Files the PA

This is the most common mistake. The pharmacy must submit the initial claim to the Bridge central processor first, that's what triggers the PA request to your doctor. If your doctor tries to file the PA before the pharmacy has submitted the claim, it won't work.

The CMS Prior Authorization Form

The PA request form is sent to your doctor by the Bridge central processor after the pharmacy submits the initial claim. If your doctor hasn't received it within 72 hours, they can download the fax form directly from CMS:

Medicare GLP Bridge Program: Prior Authorization Fax Form (CMS)

Official CMS prior authorization request form for prescribers. Your doctor uses this to request Bridge coverage for Wegovy, Zepbound, or Foundayo for weight loss. Must be completed and signed by the prescribing physician. The form is submitted to the Bridge central processor, not to your Part D plan.

How Billing Works: The CMS Pilot Has Its Own System

The GLP-1 Bridge is not a Part D drug benefit. It's a separate CMS pilot program with its own payment system. CMS selected Humana as the central processor for all Bridge claims nationwide, but this does not mean you need a Humana plan. Every Bridge claim in the country, regardless of what plan you're enrolled in, routes through Humana using the same BIN and PCN.

Billing Rules at a Glance

Who pays for the drug?CMS funds the drug cost through the pilot program. Your Part D plan does not pay for Bridge drugs.

Your copay$50 flat, same for every covered drug and every dose. No co-insurance, no deductible.

Counts toward TrOOP / $2,100 cap?No. The $50 does not count toward your True Out-of-Pocket total. It will not help you reach your $2,100 Part D OOP cap faster (increasing to $2,400 in 2027).

Counts toward Part D deductible?No. Bridge claims sit outside the Part D benefit entirely.

Coordination of benefits (COB)?No secondary payer can be applied to a Bridge claim.

Bridge vs. Part D billingFor Bridge-eligible claims, the Bridge replaces Part D billing. The same claim cannot go to both.

Mail-order pharmacyAsk your plan. Not all plans support Bridge billing through mail-order. Retail pharmacy is the safe default.

Switching drugsIf you switch from one covered Bridge drug to another, a new PA is required.

Pharmacist's Take: Tyler Dalton, PharmD

The GLP Bridge Program is genuinely good news for obesity patients who have been locked out of Medicare coverage. A flat $50 with a 72-hour PA decision is straightforward compared to standard Part D prior authorization fights. But I want to make sure you go in with clear expectations.

The biggest clinical misconception I'm already seeing: patients assuming sleep apnea or high blood pressure at any level qualifies them. That's not accurate. The BMI tiers are specific. Moderate-to-severe sleep apnea is actually a disqualifier. Uncontrolled hypertension at Tier 2 means blood pressure above 140/90 mmHg that is not adequately controlled with antihypertensive medication. Your doctor needs to document this specifically.

The second thing that will slow people down is the pharmacy workflow. The claim goes to the pharmacy first, then the PA goes to the doctor, in that order. If your doctor calls the Bridge to file a PA before your pharmacy has submitted the claim, it won't work. Make sure your pharmacy knows to submit to BIN 028918 / PCN MEDDGLP1BR first.

Finally, plan for December 2027. If you're achieving results on Wegovy or Zepbound, start that conversation with your doctor now. The Bridge expires at the end of 2027 and there is no confirmed permanent program yet.

Frequently Asked Questions

It works with any eligible Medicare Advantage (MA-PD) or standalone Part D plan. You do not need to be on a specific plan. Humana is the central processor for the entire program nationwide, that does not mean you need to enroll in a Humana plan.

No. Because the Bridge is a separate CMS pilot program outside of the Part D benefit, the $50 copay does not count toward TrOOP (True Out-of-Pocket). It has no effect on your other prescription drug costs or when you reach your $2,100 cap.

No, and this is important. Moderate-to-severe sleep apnea is a disqualifying condition for the Bridge program. Patients with that diagnosis must request GLP-1 coverage through their Part D plan instead of the Bridge.

It depends on how severe your high blood pressure is. The Bridge requires "uncontrolled hypertension", specifically, a systolic BP above 140 mmHg or diastolic above 90 mmHg, despite being on two antihypertensive medications. If you're on one or two medications and your blood pressure is well-controlled, that does not qualify. Talk to your doctor about your specific numbers.

After, this is the opposite of what many people assume. The pharmacy must submit the initial claim to the Bridge central processor first. That triggers the Bridge to send the PA request form to your doctor. Only then does the doctor complete and return the PA. If your doctor files the PA before the pharmacy claim is submitted, it will not work.

No. Only the Zepbound® KwikPen® formulation is covered under the Bridge. The single-dose Zepbound pen and Zepbound vials are specifically excluded by CMS.

A new prior authorization is required when you switch from one covered Bridge drug to another. The original PA only covers the specific drug that was approved.

The Bridge normally sends the form to your doctor electronically or by fax after the pharmacy submits the initial claim. If your doctor hasn't received it within 72 hours, they can download the fax form directly at cms.gov/glp-1-bridge.pdf.
