Glucagon-like peptide-1 (GLP-1) receptor agonists like semaglutide (Wegovy) and tirzepatide (Zepbound) are increasingly popular for weight management, but their high cost—around $1,000 per month without insurance—poses a significant barrier for many. This guide explains how to understand your insurance coverage, navigate prior authorization requirements, and explore alternative options if coverage is denied.
Understanding Insurance Policies
Insurance coverage for GLP-1 medications varies widely. Most plans require specific criteria, such as a body mass index (BMI) of 30 or higher, or a BMI of 27+ coupled with obesity-related health conditions like high blood pressure or type 2 diabetes. Coverage policies have become stricter in recent years, with some insurers dropping weight loss coverage altogether. This trend reflects the financial pressures on insurance companies to control costs while acknowledging the long-term health benefits of these medications.
Importantly, GLP-1s prescribed for conditions like type 2 diabetes typically remain covered. This distinction highlights how insurance prioritizes treating existing diseases over preventative weight loss measures.
Checking Your Coverage
The first step is reviewing your plan’s “summary of benefits and coverage,” usually available on your insurer’s website. You can also use manufacturer tools (like Wegovy’s coverage checker) for preliminary estimates. However, the most reliable method is calling your insurance provider directly.
When you speak to a representative, ask:
- Does my plan cover Wegovy or Zepbound for weight loss?
- What are the specific BMI and health condition requirements?
- Is prior authorization required?
- What documentation does my doctor need to submit?
- What are my out-of-pocket costs if approved?
Prior Authorization Process
If your plan covers GLP-1s, you’ll likely need prior authorization. This means your doctor must submit documentation proving medical necessity. Insurers typically require:
- BMI of 30 or higher, or 27+ with a related condition.
- Proof of prior unsuccessful weight loss attempts (diet, exercise, behavioral programs).
- Relevant lab results (fasting glucose, cholesterol levels).
- A letter from your doctor explaining why the medication is medically necessary.
Insurance companies often require evidence that the patient has tried and failed more affordable weight loss methods first, ensuring that medication is considered only after other interventions have been exhausted.
Appealing a Denial
If your request is denied, don’t give up. Call your insurer to understand the reason. Some denials are unavoidable (e.g., plans that don’t cover weight loss at all). But if the denial is due to unmet criteria, work with your doctor to resubmit with additional documentation.
For other denials, file an appeal:
- Have your doctor review records to ensure everything supporting your case is documented.
- Follow your insurer’s appeal instructions (usually in the denial letter).
- Submit supporting documentation, including a peer-to-peer review request where your doctor speaks directly with the insurer’s medical director.
Effective appeals require clear, concise documentation and persistence in arguing for medical necessity.
Medicare, Medicaid, and Savings Programs
Medicare currently doesn’t cover GLP-1s for weight loss due to federal law. The Treat and Reduce Obesity Act, which could change this, has been reintroduced in Congress but faces an uncertain future. However, Medicare does cover certain GLP-1s when prescribed for conditions like heart disease or liver problems, with weight loss as a secondary benefit.
Medicaid coverage varies by state, with some programs covering GLP-1s while others require step therapy (trying cheaper medications first).
Both Wegovy and Zepbound manufacturers offer savings programs, but these are typically unavailable for government insurance plans.
Affordable Alternatives
If GLP-1s aren’t an option, consider these alternatives:
- Orlistat (Xenical)
- Phentermine (Adipex-P)
- Phentermine/topiramate (Qsymia)
- Naltrexone/bupropion (Contrave)
- Liraglutide (Saxenda)
While some alternatives are nearly as expensive as GLP-1s, others are more affordable, though their effectiveness varies. Compounded GLP-1s (mixed with other drugs) are cheaper but carry risks due to lack of FDA oversight.
Conclusion
Obtaining insurance coverage for GLP-1 weight loss medications requires navigating complex policies, meeting strict criteria, and potentially appealing denials. Understanding your plan, working with your doctor, and exploring alternative options are crucial steps. Ultimately, lasting weight loss success depends on a comprehensive approach that combines medication with lifestyle changes.
