Is Zepbound Covered by Medicare? Eligibility & Cost Insights

Zepbound is a once-weekly injectable medication approved for chronic weight management in adults with obesity or those who are overweight with at least one weight-related condition. The active ingredient in Zepbound is tirzepatide, which also powers the diabetes drug Mounjaro. Zepbound belongs to a class of medications called GLP-1 receptor agonists but uniquely targets both GLP-1 and GIP receptors—dual-action hormones that regulate appetite and blood sugar. If you’re wondering, is Zepbound covered by Medicare? The answer may depend on your specific plan and whether it’s prescribed for an approved medical need. Zepbound is FDA-approved for individuals with a BMI of 30 or higher, or a BMI of 27 or higher with conditions like type 2 diabetes, high blood pressure, or sleep apnea.

Who Should Use Zepbound?

Not everyone needs or qualifies for Zepbound. It’s specifically designed for:

• Adults with obesity (BMI ≥30)

• Adults who are overweight (BMI ≥27) with at least one comorbid condition

• Individuals who have tried diet and exercise without long-term success

Patients must undergo evaluation by a healthcare provider to determine if Zepbound is appropriate. It’s not recommended for those with a personal or family history of medullary thyroid carcinoma or multiple endocrine neoplasia syndrome type 2.

How Zepbound Works for Weight Loss

Zepbound mimics two natural hormones—GLP-1 and GIP—that influence appetite, digestion, and insulin secretion. These hormones:

• Slow down gastric emptying

• Increase feelings of fullness

• Reduce cravings and caloric intake

• Enhance insulin sensitivity

The result? Clinically proven weight loss of up to 20% or more in some participants over a 72-week period. For many, Zepbound outperforms older medications like Saxenda and Qsymia.

Why Zepbound Gained Popularity in 2025

Zepbound has quickly become a household name in 2025 for several reasons:

• Exceptional weight loss results in clinical trials

• Backing from major obesity specialists and endocrinologists

• Social proof through testimonials, social media influencers, and celebrity endorsements

• Growing recognition of obesity as a chronic disease, not a lifestyle choice

Zepbound isn’t just about aesthetics—it’s a metabolic intervention with the potential to prevent complications like diabetes, heart disease, and joint issues.

What Medicare Typically Covers

To understand if Zepbound is covered by Medicare in 2025, we must first explore how Medicare works.

Medicare Coverage Parts:

• Part A: Hospital insurance (no drug coverage)

• Part B: Outpatient care, preventive services (limited drug coverage)

• Part D: Prescription drug coverage (covers medications not administered in a clinical setting)

• Medicare Advantage (Part C): Private plans that may offer additional benefits beyond Original Medicare

Zepbound falls under Part D or Medicare Advantage drug plans, depending on the provider’s formulary and prior authorization rules.

Is Zepbound Covered by Medicare in 2025?

The Short Answer: Sometimes—But Not Always.

As of 2025, Original Medicare does not consistently cover Zepbound, especially under Part B. However, Medicare Part D and Medicare Advantage plans may offer partial coverage depending on the plan provider, tier placement, and individual eligibility.

Each insurer determines:

• Formulary inclusion (is Zepbound even listed?)

• Tier placement (is it a Tier 3, 4, or 5 specialty drug?)

• Prior authorization (does your doctor need to justify the prescription?)

• Step therapy requirements (do you have to try cheaper drugs first?)

Medicare Part D and Zepbound

Zepbound may be included in some Medicare Part D formularies as of 2025, but the following issues still apply:

• It’s often labeled a Tier 4 or Tier 5 drug, meaning higher copays or coinsurance

• Prior authorization is almost always required

• Estimated monthly costs with Part D: $250–$400 depending on the plan

Plans also impose coverage limits or exclusions due to Zepbound being primarily labeled as a “weight loss drug” rather than a treatment for chronic disease.

Medicare Advantage and Zepbound Coverage

Medicare Advantage (Part C) plans vary widely. Some may offer enhanced drug benefits that include Zepbound with:

• Lower copays

• Streamlined authorization

• Access to obesity management programs

In 2025, some high-tier Medicare Advantage plans have started experimenting with Zepbound inclusion, especially for patients with obesity-related comorbidities.

Prescription Drug Plans and Zepbound

With standalone PDPs (Prescription Drug Plans), Zepbound is:

• Sometimes excluded due to its classification as a lifestyle drug

• Subject to coverage gap (“donut hole”) pricing increases

• Highly variable in out-of-pocket cost ($300–$1,200/month if denied coverage)

It’s essential to check each plan’s formulary tool or consult with a Medicare advisor.

Out-of-Pocket Costs for Zepbound in 2025

If not covered, Zepbound costs approximately $1,059/month without insurance.

With Medicare or Part D, costs may still be:

• $250–$500 per month

• Subject to deductibles and tier pricing

• Reduced through manufacturer savings programs or state assistance

Alternatives to Zepbound That Medicare May Cover

Some weight loss or diabetes drugs are more commonly covered under Medicare, including:

• Wegovy (semaglutide)

• Saxenda

• Ozempic (approved for diabetes but often prescribed off-label)

These may be preferred by insurers due to longer market history and lower cost.

Does Any Insurance Cover Zepbound in 2025?

Yes—private health insurance plans, ACA marketplace plans, and some Medicaid programs may offer partial or full coverage of Zepbound.

Factors affecting coverage:

• State-level Medicaid policies

• Employer group plan benefits

• Insurance tier (bronze vs platinum)

Check your insurer’s formulary or call their pharmacy benefits helpline.

Strategies to Get Zepbound Covered

If Medicare or insurance denies Zepbound, try these approaches:

1. Doctor’s Letter of Medical Necessity

2. Appeal the decision

3. Try step therapy (e.g., Ozempic first)

4. Use manufacturer savings cards

5. Request samples

6. Switch to a Medicare Advantage plan during open enrollment

Are Any Weight Loss Drugs Covered by Medicare?

Yes, but limited:

• Drugs with dual approvals (diabetes + weight loss) like Ozempic may be covered

• Saxenda may be covered for patients with high BMI and comorbidities

• Medicare generally does NOT cover cosmetic or lifestyle weight loss meds

Coverage depends on how the drug is positioned: therapeutic vs lifestyle.

Zepbound and Seniors: Medicare Realities

For seniors 65+, the road to Zepbound coverage isn’t easy.

• Part B excludes it

• Part D may require prior authorization

• Medicare Advantage plans vary significantly

Still, with obesity impacting over 40% of seniors, the demand for Zepbound continues to rise in 2025, and insurers are under pressure to adapt.

Legislative Changes on Medicare and Weight Loss Drugs

In 2025, lawmakers are considering bills to:

• Reclassify obesity medications as chronic disease treatments

• Allow broader Medicare coverage for drugs like Zepbound

• Reduce out-of-pocket costs for low-income seniors
