Aetna Medicare's coverage of Wegovy varies by plan and changes year to year
Aetna Medicare does cover Wegovy (semaglutide) for weight management in some of its plans, but not all. Whether your specific Aetna plan covers it depends on which Medicare Advantage or Medigap plan you have, what your doctor prescribes it for, and whether you meet the plan's medical necessity requirements. Coverage also shifts annually when plans renew their formularies — the official list of drugs they will pay for.
Wegovy is a prescription injection used for chronic weight management in adults with obesity or who are overweight with weight-related health conditions. Because it is a newer drug and relatively expensive, not every Medicare plan covers it, and those that do often require prior authorization from your doctor before the pharmacy will fill your prescription.
The best way to find out whether your Aetna plan covers Wegovy is to call the member services number on your insurance card, have your plan name and number ready, and ask directly. You can also check your plan's formulary online through your Aetna account or by visiting Aetna's website and searching for your specific plan year.
Key Takeaways
- Aetna Medicare covers Wegovy in some plans but not others, and coverage changes each year when plans update their drug lists.
- Your doctor will likely need to request prior authorization before your pharmacy can fill a Wegovy prescription, which takes several business days.
- You can check whether your plan covers Wegovy by calling Aetna member services or reviewing your plan's formulary online.
- If your Aetna plan does not cover Wegovy, you may be able to appeal the decision or explore other weight management medications your plan does cover.
- Cost-sharing for Wegovy — your copay or coinsurance — depends on which tier your plan places the drug on and your specific plan design.
How to check your Aetna plan's Wegovy coverage
Start by locating your plan documents. If you have an Aetna Medicare Advantage plan, log into your Aetna account online and look for the formulary or drug list for your plan year. The formulary lists every drug your plan covers, what tier it is on (which determines your out-of-pocket cost), and any restrictions like prior authorization or quantity limits.
Search the formulary for "semaglutide" — that is Wegovy's generic name — and note which tier it appears on. Tier 1 drugs usually have the lowest copay, while higher tiers cost more. If you do not see it listed, the drug is not covered by your plan.
If you cannot find the formulary online or want to confirm coverage before your doctor writes a prescription, call the member services number on your insurance card. Have your plan name, plan number, and the drug name ready. Ask whether Wegovy is covered, what your copay or coinsurance would be, and whether your doctor needs prior authorization.
Prior authorization and what your doctor needs to do
Most Aetna Medicare plans that cover Wegovy require prior authorization — meaning your doctor must submit a request to Aetna explaining why you need the drug before the pharmacy will fill your prescription. This is not a denial; it is a standard review step that usually takes three to five business days.
Your doctor's office handles this request. They will send Aetna your medical records, your weight, your body mass index (BMI), and any weight-related conditions you have — such as type 2 diabetes, high blood pressure, or heart disease. Aetna reviews this information against its medical necessity criteria and either approves or denies the request.
If Aetna approves the prior authorization, your doctor can write the prescription and you can pick it up at the pharmacy. If Aetna denies it, your doctor can appeal the decision by providing additional medical information, or you can explore other weight management options your plan does cover.
What to expect for out-of-pocket costs
If your Aetna plan covers Wegovy, your cost depends on which tier the drug is on and your plan's cost-sharing structure. Some plans use a flat copay per injection (for example, $50 per month's supply), while others use coinsurance, meaning you pay a percentage of the drug's cost after your deductible is met.
Wegovy is expensive — the full retail price is several hundred dollars per month — so even with insurance, your copay or coinsurance may be substantial. Ask Aetna member services what your specific out-of-pocket cost would be before your doctor prescribes it. Some people find that the cost is manageable; others decide to explore less expensive alternatives.
If the cost is too high, talk to your doctor about other weight management medications your plan covers, or ask whether a lower dose of Wegovy might be available at a lower cost tier. Some plans also have patient information programs or mail-order pharmacy discounts that can reduce your cost.
What happens if your Aetna plan does not cover Wegovy
If your plan's formulary does not include Wegovy, you have several options. First, you can ask your doctor to request a formulary exception — a formal request to Aetna to cover a drug that is not normally on the plan's list. Your doctor explains your medical situation, why Wegovy is medically necessary for you, and why other covered alternatives would not work as well. Aetna reviews this request and may approve it.
Second, you can pay for Wegovy out of pocket. The retail cost varies by pharmacy and dosage, but expect to pay several hundred dollars per month. Some manufacturers offer patient information programs that reduce the cost for people who meet income requirements.
Third, you can ask your doctor about other weight management medications that your Aetna plan does cover. These may include older drugs like phentermine or newer options like GLP-1 receptor agonists that your plan has chosen to include on its formulary.
When to contact your doctor or Aetna
Contact your doctor if you are interested in Wegovy for weight management and want to know whether it is appropriate for you. Your doctor will review your medical history, weight, and any weight-related conditions to decide whether to prescribe it.
Contact Aetna member services if you have questions about whether your plan covers Wegovy, what your cost would be, or whether prior authorization is required. Call the number on your insurance card during business hours. Have your plan information ready.
Contact Aetna again if your doctor requests prior authorization and you do not hear back within a week, or if Aetna denies the prior authorization and you want to appeal. Your doctor's office can also follow up on a pending authorization request.
