It depends on your plan. Each insurance company decides when it covers GLP-1 medications for weight loss, says Andres Sasson, MD, chief medical officer and cofounder of Lighthouse Weight Loss in Tampa, Florida. Most plans require you to meet certain criteria, such as having a specific body mass index (BMI) or a high BMI plus a related health condition like high blood pressure or high cholesterol.
Over the past few years, insurance companies have added stricter coverage requirements for GLP-1s used for weight loss, while others have stopped covering these medications altogether. But these changes generally don’t affect GLP-1s prescribed for other approved health conditions, like type 2 diabetes, which remain covered under most plans.
According to Dr. Sasson, part of the reason that insurance doesn’t cover GLP-1s for weight management has to do with cost and timing. GLP-1 medications can significantly improve long-term health by reducing the risk of heart disease, stroke, and other complications. He explains that because people often change insurance plans every few years, one health plan may pay for the medication, but another may see the financial savings from that person’s improved health.
How to Check if Your Insurance Covers GLP-1 Obesity Medications
Start by reviewing your plan’s summary of benefits and coverage, which outlines covered services, says Jennifer Brown, MD, a board-certified obesity medicine doctor at MyObesityTeam. This document is usually sent to you at the beginning of your enrollment year, and you can often find it on your insurance company’s website.
If you’re interested in Wegovy, you can also check coverage and costs through its manufacturer’s coverage tool.
But calling your insurance company is often the best way to check coverage and eligibility requirements. When you speak with an insurance representative, here are some questions to ask:
Does my plan cover Wegovy or Zepbound for weight loss?
What are the specific criteria I need to meet for coverage, such as BMI requirements and health conditions?
Is prior authorization required?
What documentation does my doctor need to submit?
Do I need to try other weight loss methods first?
What will my out-of-pocket cost be if approved?
How long does the approval process take?
How to Submit a Prior Authorization Request
Once you confirm that your plan covers GLP-1 medications, the next step is meeting the requirements for approval. Dr. Brown explains that most insurers cover GLP-1s for weight loss when you meet one of the following criteria:
BMI of 30 or higher
BMI of 27 or higher with at least one weight-related health condition, such as high blood pressure or type 2 diabetes.
Insurers may want proof that you’ve tried to lose weight through lifestyle changes before turning to medication, says Neika Small, a board-certified nurse practitioner and weight loss expert at NuNava Health. This means that you’ll need to provide documentation of weight loss efforts like diet changes, exercising, or behavior-based programs that weren’t successful.
Small recommends having the following ready when submitting a request for coverage:
Your BMI and recent weight history
Medical records showing past attempts to lose weight
Lab results, like fasting glucose, hemoglobin A1C, and cholesterol levels
A letter from your healthcare provider explaining why the prescribed medication is medically necessary
Your provider’s office will usually handle the prior authorization process and send these documents to your insurance company for review. If approved, you’ll get a notification from your insurer letting you know how to fill your prescription. If denied, you have options.
Insurance Appeals
If your insurance denies coverage for a GLP-1 obesity medication, the first step is to call your health plan and find out why, says Brown. Some plans don’t cover weight loss medications at all, and if that’s the case, unfortunately, an appeal won’t change the outcome, she says.
In other situations, the denial may be because certain requirements haven’t been met yet. For example, some insurers require you to complete a three-month, physician-supervised weight loss program before approving the medication, says Brown. Once you complete those steps, your provider can resubmit the prior authorization request.
For other types of denials, you can file an appeal. To begin the process:
Ask your provider to review your records to make sure everything that supports your need for the medication is clearly documented, says Small.
Follow your insurer’s appeal instructions, which are usually included in the denial letter or on its website.
Work with your provider to submit any additional supporting documentation.
Your provider can also request a peer-to-peer review, during which they speak directly with a healthcare reviewer or medical director from your insurance company to clarify details and advocate for your case. “In my experience with effective appeals and peer-to-peer review cases, success was always a result of clear, concise documentation and persistence with the argument,” says Small.
She adds that when your provider presents obesity treatment as part of managing a long-term health condition and explains how the medication can improve blood sugar, cholesterol, and weight over time, it helps strengthen your case for medical necessity.
Medicare and Medicaid
Medicare doesn’t cover GLP-1 medications when they’re prescribed specifically for weight loss, says Brown. Federal law has long prevented Medicare from covering weight loss medications. In April 2025, federal officials reaffirmed this position, confirming that Medicare and Medicaid will not cover anti-obesity medications, including GLP-1s, through 2026.
Despite this decision, there’s an ongoing effort to change this policy, Brown says. The Treat and Reduce Obesity Act, which would allow Medicare Part D to cover obesity medications approved by the U.S. Food and Drug Administration (FDA), was introduced in 2023 but didn’t pass. It was reintroduced in early 2025 and is currently making its way through Congress.
That said, Medicare may cover certain GLP-1 drugs when they’re prescribed for other health reasons. Medicare Part D now includes coverage for semaglutide when it’s used to lower the risk of heart attack and stroke in adults with obesity and existing heart disease.
Semaglutide was also approved to treat a liver condition known as metabolic dysfunction-associated steatohepatitis in adults with moderate to advanced liver scarring. Because these uses are considered medical, not cosmetic, they may qualify for coverage. And when GLP-1s are prescribed for these other health conditions, weight loss often happens as a side effect of the treatment.
Medicaid coverage varies by state. Small notes that some state programs cover GLP-1 medications for weight management, while others don’t cover any weight loss drugs at all. “Others have a step therapy process in place, in which cheaper weight loss medications have to be tried first before they’ll cover GLP-1 medications,” says Brown.
Coverage rules can change depending on state funding and policy updates, so it’s best to check directly with your state’s Medicaid program to see what’s covered and what criteria apply.
