Step-by-step guide to getting prior authorization for Wegovy or Zepbound, what to do if denied, and which telehealth providers handle the paperwork for you.
Most people with insurance assume that if their doctor prescribes something, the insurer pays for it. GLP-1 medications don't work that way. Wegovy and Zepbound almost always require prior authorization before your plan will cover them, and many patients don't find out until the prescription is already sitting at the pharmacy.
This guide walks through exactly how prior authorization works for GLP-1s, what you need to qualify, and how to fight back if your first request is denied.
Answer a few questions and we'll match you with providers that manage prior auth on your behalf.
Take the free quiz →Prior authorization (PA) is a cost-control requirement that insurers use to make sure a medication is medically necessary before they agree to cover it. For most drugs, PA is a routine backstop. For GLP-1s, it's a genuine hurdle.
Wegovy (semaglutide 2.4 mg) and Zepbound (tirzepatide) can cost $1,000 or more per month at retail price. Insurers require PA to verify that you meet specific clinical criteria before covering that cost. Employer-sponsored plans often have additional restrictions, and many Medicaid programs still exclude GLP-1s for weight loss entirely.
The process adds time and paperwork. But it is worth doing, because commercially insured patients who successfully get coverage can pay as little as $25 per month with the Wegovy Savings Offer for eligible plans (per wegovy.com, April 2026).
Most commercial plans follow the FDA-approved indications for these drugs. For Wegovy and Zepbound, the prescribing criteria require either:
These thresholds come directly from the FDA-approved labels for both medications (Wegovy prescribing information, FDA.gov; Zepbound prescribing information, FDA.gov).
Beyond BMI, many insurers add requirements of their own. Common extras include:
Some plans also require that you have been a member for a minimum period before a GLP-1 will be covered. Check your Summary of Benefits or call your plan's member services line to confirm the specific criteria before your provider submits anything.
A telehealth provider who handles prior auth support makes this significantly easier. Providers like Ro, PlushCare, Found, and Mochi Health all offer insurance coordination as part of their programs. Your provider's team assembles the clinical documentation and submits the PA request to your insurer on your behalf.
If you're working with a primary care doctor who doesn't typically manage PA for GLP-1s, you may need to be more proactive. Ask the practice explicitly: "Does someone on your staff handle prior authorization submission and follow-up?"
The PA request goes from your provider to your insurer and includes the prescription, a letter of medical necessity, relevant diagnosis codes, lab results, and documentation of prior weight loss attempts if required. Completeness matters. Missing documentation is one of the most common reasons for initial denials.
PlushCare's care team automatically compiles required documentation once a GLP-1 is prescribed and handles the submission, with insurance review typically taking 7 to 14 business days (per PlushCare website, April 2026). Ro's insurance concierge works directly with your insurer and manages the entire process, though they note the timeline can extend to 2 to 3 weeks or longer if additional information is requested (per Ro website, April 2026).
Once the insurer has the complete submission, they have a defined window to respond. For urgent requests, federal regulations require a response within 72 hours. For standard non-urgent requests, the window is generally up to 30 calendar days under federal PA rules, though many plans respond faster.
During this period, the insurer may come back with requests for additional information. Respond quickly, and keep copies of everything.
Once approved, confirm your out-of-pocket cost before filling the first prescription. Commercially insured patients who use the Wegovy Savings Offer may pay as little as $25 per month, with a maximum savings of $100 per month through that program (per wegovy.com, April 2026). Note that government insurance plans including Medicare and Medicaid do not qualify for manufacturer savings offers.
A denial is not the end. Most PA denials can be appealed, and the appeals process has real teeth because insurers are required to explain the specific reason for a denial.
The explanation of benefits or denial notice will give you a specific reason, usually one of these:
Each reason calls for a different response.
You have the right to file an internal appeal with your insurer. Your provider submits a letter addressing the specific reason for denial, often with additional clinical evidence. If the reason was missing documentation, this is often resolved at this stage.
Ask your provider explicitly whether they will handle the appeal on your behalf. Ro and PlushCare both offer ongoing prior auth support for this reason.
If the denial was based on medical necessity, your prescribing provider can request a peer-to-peer review. This is a phone call between your doctor and the insurer's medical reviewer. Clinical providers with experience in obesity medicine may have better outcomes in these conversations, particularly if they can speak to specific comorbidities and prior treatment history that weren't fully captured in the initial submission.
If your internal appeal is denied, you can request an independent external review. An independent reviewer not affiliated with your insurer evaluates the case. Under the Affordable Care Act, insurers are required to accept the outcome of external reviews for most plan types. This is the strongest tool available if the insurer is applying criteria that don't align with medical evidence.
Some employer plans explicitly exclude weight loss medications. This is a harder situation. Your options are:
Not every GLP-1 telehealth provider will do the insurance legwork for you. Some specialize in it. Here's a quick breakdown of the providers that stand out for insurance coordination.
Note: Some providers listed here also offer compounded semaglutide or tirzepatide, which use the same active ingredients as Wegovy and Zepbound but are not FDA-approved as finished products. This guide focuses on brand-name medication coverage. Ask your provider which option is appropriate for your situation.

Mochi Health and WeightWatchers Clinic both offer insurance navigation support within their clinical care programs, though the depth of PA handling varies. If your primary goal is maximizing insurance coverage, Ro and PlushCare are the two providers most purpose-built for it.
Hims and providers like LillyDirect are designed primarily for cash-pay patients and do not provide prior authorization assistance. They're good fallback options if insurance coverage doesn't work out, but not the right starting point if you want to use your insurance.
A few developments in early 2026 are worth knowing about.
Wegovy oral pill cash-pay pricing. Novo Nordisk's oral semaglutide formulation is now available through NovoCare Pharmacy for patients paying cash, starting at $149 per month for the 1.5 mg dose (per wegovy.com, April 2026). The pen form starts at $199 per month for the first two months at starter doses, then $349 per month. These prices apply to patients without insurance coverage or while waiting for PA approval.
Medicare and GLP-1s. Traditional Medicare Part D has historically excluded drugs approved solely for weight loss. This has been an area of active policy discussion, but as of April 2026, standard Medicare does not cover Wegovy or Zepbound for weight management in most cases. If you have Medicare Advantage, your specific plan may have different coverage rules. Check your plan's formulary directly and ask your provider whether they have experience submitting PA for Medicare Advantage plans.
Cardiovascular indication coverage. Wegovy received FDA approval for reducing cardiovascular risk in adults with established cardiovascular disease and obesity or overweight, based on the SELECT trial (NEJM, 2023). Some insurers may cover Wegovy under this cardiovascular indication for qualifying patients even when their formulary excludes weight loss drugs — coverage policies vary by plan and are evolving as the evidence base grows. If you have a history of heart attack, stroke, or established heart disease, ask your provider whether the cardiovascular indication is more likely to get approved under your specific plan, and confirm directly with your insurer before assuming this pathway applies.
Prior authorization for GLP-1s is real work, but it's manageable. The key is starting with a provider who handles it for you, submitting a complete packet the first time, and knowing your appeal rights if you get denied. A denial is not a final answer.
