Medicare Is Covering Weight Loss Medications — What You Need to Know Before July 1

YOUR MONEY — Issue No. 10

The Medicare GLP-1 Bridge program launches July 1. Here is what it covers, who qualifies, and what to do right now.

Something significant is happening in Medicare on July 1 — and most people haven't heard about it yet.

For the first time, Medicare will begin covering certain GLP-1 weight loss medications for eligible beneficiaries at a flat $50 per month copay. Medications that have been costing patients hundreds of dollars per month out of pocket.

A quick note: this issue is shorter than our typical format. The Medicare GLP-1 Bridge launches July 1 — and getting this information to you clearly and quickly matters more than length this week.

GLP-1 medications were originally developed to treat Type 2 diabetes. Researchers later discovered that they also produced significant weight loss — prompting the FDA to approve higher doses specifically for obesity treatment.

For years, Medicare patients with obesity paid hundreds of dollars per month for these medications out of pocket. Medicare was prohibited by law from covering medications prescribed solely for weight loss. The Medicare GLP-1 Bridge changes that.

What the Medicare GLP-1 Bridge actually is

The Bridge is a temporary federal demonstration program running from July 1, 2026, through December 31, 2027. It operates outside of the standard Medicare Part D benefit — meaning it runs through a central CMS processor rather than your individual insurance plan. Humana has been selected as the central processor managing prior authorizations for the Bridge.

Three medications are covered under the Bridge:

All three are covered for weight management only — at a flat $50 per month copay, regardless of which medication you use. Your specific insurance company is not involved in the Bridge's operations.

A few important coverage details:

Who qualifies — the three pathways

Not every Medicare patient qualifies. Eligibility depends on your BMI and your medical history. There are three qualifying pathways:

Pathway 1 — BMI of 35 or higher:
You qualify based on BMI alone. No additional diagnosis is required. This is the broadest pathway and covers the majority of patients who will be eligible.

Pathway 2 — BMI of 30 or higher with one of the following:

Pathway 3 — BMI of 27 or higher with one of the following:

All three pathways also require:

One important nuance:
Eligibility is based on your BMI and diagnosis at the time you first started GLP-1 therapy — not necessarily at the time of the prior authorization request. If you started a GLP-1 medication in 2024 with a BMI of 38 but have since lost weight and your BMI is now 34 — your provider can attest that you met the criteria when therapy began. You may still qualify.

Who does NOT qualify for the Bridge

This is important — and widely misunderstood.

If you have Type 2 diabetes, obstructive sleep apnea, or a liver condition called MASH (metabolic dysfunction-associated steatohepatitis) — your GLP-1 medication is covered through your standard Medicare Part D plan, not the Bridge. Patients with these diagnoses are specifically excluded from the Bridge program, even if they otherwise meet the BMI criteria.

This means your cost sharing depends on your specific Part D plan and which tier your medication falls on — which may be significantly higher than $50 per month.

If you have one of these diagnoses and are currently paying high out of pocket costs for a GLP-1 — talk to your provider about your Part D formulary and whether a prior authorization could help reduce your cost. The $2,100 annual Part D out of pocket cap that took effect in 2026 also provides some protection once you reach that threshold.

How the prescribing process works

Getting a GLP-1 through the Bridge is not as simple as calling your doctor and picking up a prescription. Here is what the process looks like:

Step 1 — Talk to your provider:
Schedule an appointment to discuss whether you meet the Bridge criteria. Your provider will review your weight, discuss your qualifying diagnosis, and go over a nutrition and physical activity plan — which is required as part of the prescription.

Step 2 — Prior authorization:
Your provider must submit a prior authorization request to Humana — the central CMS processor specifically created for the Bridge — not to your insurance plan. This is different from how prior authorizations normally work. Your insurance company is not the decision maker here.

Prior authorization cannot be submitted until July 1 when the program officially launches. Plan accordingly — talk to your provider before July 1 so you are ready to move quickly when the program opens.

Step 3 — Pharmacy:
Your pharmacy must use a specific billing code assigned to the Bridge program. Most major pharmacies will have this set up by July 1. When you pick up your medication, you pay the flat $50 copay directly at the pharmacy.

What happens after December 31, 2027

The Bridge is temporary by design. It is intended to serve as a transition to the BALANCE Model — Better Approaches to Lifestyle and Nutrition for Comprehensive Health — which CMS is developing as a longer-term Medicare obesity care program beginning in 2027.

The details of BALANCE are still being finalized. What is known is that it will expand on the Bridge's framework with a more comprehensive approach to obesity treatment — potentially including behavioral health, nutrition counseling, and ongoing medication access.

The honest answer: we don't know exactly what coverage will look like after December 31, 2027. What we do know is that the Bridge represents a significant shift in how Medicare views obesity — from a lifestyle issue to a medical condition that warrants treatment. That shift is unlikely to reverse.

What to do right now

If you think you or someone you know may qualify:

1. Know your approximate BMI. If you see your primary care provider regularly, your BMI is automatically calculated when your height and weight are recorded — it will be in your chart. If you haven't been seen recently, a simple online BMI calculator takes 30 seconds. Either way, knowing your approximate number before your appointment helps the conversation move faster.

2. Review your diagnoses. Do you have uncontrolled hypertension on at least two medications, pre-diabetes, heart failure, CKD Stage 3 or worse, a prior heart attack, a prior stroke, or peripheral artery disease? Any of those combined with the right BMI may qualify you.

3. Schedule an appointment before July 1. Talk to your provider now so you are ready to move quickly when the program opens. Prior authorization cannot be submitted until July 1 — but having that conversation early means you won't be starting from scratch when the program launches. When you go — ask directly: "Do I qualify for the Medicare GLP-1 Bridge program? Can we prepare so we are ready to submit the prior authorization as soon as it opens?"

4. Confirm your Part D enrollment. You must be enrolled in a Medicare Part D plan to access the Bridge. If you are not currently enrolled — contact Medicare at 1-800-633-4227.
