Getting Wegovy covered by insurance requires meeting specific clinical criteria, navigating prior authorization, and sometimes appealing a denial. The process varies significantly depending on whether you have commercial insurance through an employer, Medicare, or Medicaid, but the core steps are the same: confirm your plan covers the drug, document that you meet the medical criteria, and work with your doctor to submit the right paperwork.
Check Whether Your Plan Covers Wegovy at All
Before anything else, find out if your health plan even includes Wegovy on its formulary. This saves you from going through weeks of paperwork only to hit a wall. Call the number on the back of your insurance card and ask specifically whether Wegovy (semaglutide for weight management) is a covered benefit. You can also look up your plan’s formulary online or check through Novo Nordisk’s coverage tool at NovoCare.com.
Many plans explicitly exclude weight loss medications, and this is more common than you might expect. Only about 19% of large employers (200 or more workers) cover GLP-1 drugs for weight loss in their largest health plan. Coverage scales with company size: 16% of firms with 200 to 999 employees cover these drugs, compared to 43% of firms with 5,000 or more workers. If your employer plan excludes weight loss drugs entirely, no amount of prior authorization or appeals will change that. Your options at that point are the manufacturer savings program, the subscription pricing model, or asking your HR department whether coverage might be added in a future plan year.
Meet the FDA-Approved Criteria
Insurance companies base their coverage decisions on FDA-approved indications, so understanding the clinical thresholds is essential. Wegovy is approved for adults who have either:
- A BMI of 30 or higher (classified as obesity), or
- A BMI of 27 to 29.9 (classified as overweight) along with at least one weight-related health condition, such as type 2 diabetes, high blood pressure, high cholesterol, or obstructive sleep apnea.
For adolescents aged 12 and older, the threshold is a BMI at or above the 95th percentile for their age and sex. Your doctor will need to document your BMI and any relevant comorbidities clearly in your medical record, because insurers will look for this documentation during prior authorization review.
Prepare for Prior Authorization
Most insurance plans require prior authorization before they’ll cover Wegovy. This means your doctor submits clinical documentation to the insurer proving that the prescription is medically necessary. Here’s where many claims get tripped up, and understanding the common requirements ahead of time makes a real difference.
Insurers typically require evidence that you’ve already tried and failed other weight management approaches before they’ll approve Wegovy. A real denial case reviewed by the New York State Department of Financial Services illustrates exactly what insurers look for. In that case, coverage was denied because the patient hadn’t documented losing at least 5% of her body weight through diet and exercise before the prescription was written. The insurer also required evidence that the patient had tried and failed other FDA-approved weight loss medications, not just one, but multiple. Simply stating that other drugs were contraindicated wasn’t enough. The insurer pushed back, noting that the specific contraindication the doctor cited (hypertension) only applied to one of those medications in its uncontrolled form, and the patient’s blood pressure records showed it was well controlled.
The lesson here is specificity. Your medical records should clearly show your weight history, any structured diet or exercise programs you’ve followed, other weight loss medications you’ve tried (and why they didn’t work or caused side effects), and documentation of weight-related health conditions. Vague statements in your chart won’t hold up. Ask your doctor to be precise about why alternatives are inappropriate for you, with clinical evidence to back it up.
What to Do If You’re Denied
A first denial isn’t the end. You have the right to appeal, and appeals can succeed when you address the specific reasons the insurer gave for denial. Your denial letter will include the exact criteria you didn’t meet. Read it carefully.
Work with your doctor to write an appeal letter that directly addresses each stated reason. If the insurer says you didn’t try other medications first, your doctor needs to document either that you did try them (with dates, dosages, and outcomes) or explain with clinical specificity why those drugs are contraindicated for you. General statements like “patient cannot tolerate other options” won’t cut it. The appeal needs to reference your actual lab values, medical history, and any documented adverse reactions.
If your first-level appeal fails, most plans offer a second level of review, and many states allow you to request an external review by an independent third party. Your state’s department of insurance or department of financial services can explain the external review process and timelines.
Medicare Coverage
Medicare historically excluded weight loss drugs from Part D coverage. That changed after the FDA approved Wegovy for a second use: reducing cardiovascular risk in people with established heart disease. The Centers for Medicare and Medicaid Services then issued guidance allowing Part D plans to add Wegovy to their formularies for this indication.
The catch is that the cardiovascular indication is narrow. You qualify if you have established cardiovascular disease, meaning a prior heart attack, prior stroke, or peripheral arterial disease, along with either obesity or overweight. Medicare Part D plans are not required to cover Wegovy purely for weight management without that cardiovascular history. Coverage comes through Part D (your prescription drug plan), not Part B, because Wegovy is a self-administered injection rather than a drug given in a medical office.
If you’re on Medicare and have the qualifying cardiovascular history, call your Part D plan to confirm whether they’ve added Wegovy to their formulary and what prior authorization steps they require.
Medicaid Coverage
Medicaid coverage for Wegovy as a weight loss drug varies by state and remains limited. As of January 2026, only 13 state Medicaid programs cover GLP-1 drugs for obesity treatment under fee-for-service. Coverage for other uses of GLP-1 drugs (diabetes, cardiovascular disease, sleep apnea) is required, but coverage for obesity treatment is optional, and several states have recently pulled back. California, New Hampshire, Pennsylvania, and South Carolina all eliminated obesity coverage for GLP-1s, while North Carolina briefly dropped coverage due to a budget dispute before reinstating it. If you’re on Medicaid, contact your state’s Medicaid office or your managed care plan to find out your state’s current policy.
The Manufacturer Savings Program
If you have commercial insurance that covers Wegovy, Novo Nordisk offers a savings card that brings your copay down to as little as $25 per month for a 28-day supply of injections or a 30-day supply of the oral tablets. The card covers up to $100 per month in savings. You need a valid prescription and commercial insurance to qualify. People enrolled in Medicare, Medicaid, or other government health programs are not eligible.
For people paying entirely out of pocket, Novo Nordisk has introduced a subscription pricing model. Monthly costs range from $329 on a 3-month plan to $249 on a 12-month plan, which saves up to $1,200 annually compared to paying month to month. This is significantly lower than the previous list price and may be worth considering if your insurance doesn’t cover the drug at all.
Steps to Maximize Your Chances
The people who get Wegovy covered most reliably tend to follow a clear sequence. First, verify your plan covers the drug before your doctor submits anything. Second, build a paper trail in your medical record over several months: documented BMI measurements at office visits, a supervised diet or exercise program, and trials of lower-cost weight loss medications with notes about why they were insufficient. Third, have your doctor submit a detailed prior authorization that anticipates the insurer’s objections, citing specific lab results and medication history rather than general statements.
If your employer plan excludes weight loss medications entirely, you still have options. Some employers add coverage in response to employee requests, particularly during benefits review periods in the fall. Contact your HR or benefits department and ask whether GLP-1 coverage is being considered. With 43% of the largest employers now covering these drugs, the trend is moving toward inclusion, and your company may already be evaluating it.
