Usually, no. Compounded GLP-1s, peptides and most wellness prescriptions are paid out of pocket, and Medicare’s drug benefit excludes weight-loss drugs by statute. Patients can sometimes use HSA or FSA money, and self-pay patients are owed a good faith estimate before they are treated. Here is what to tell a patient who asks.
Compounded drugs sit outside most coverage
A compounded drug is made for one patient from bulk ingredients. Insurers build formularies around approved products, and compounded medications usually fall outside them.
For Medicare the rule is in writing. CMS’s Part D manual says bulk powders “do not satisfy the definition of a Part D drug and are not covered by Part D,” and that compounded products as a whole generally don’t qualify either [CMS Part D Manual, Ch. 6]. FDA’s point is the other half of the explanation: compounded drugs “are not FDA approved,” and FDA does not review them for safety, effectiveness or quality [FDA].
Commercial plans vary, and no single public rule covers all of them. Coverage depends on each plan’s formulary and exclusions. Assume self-pay unless a patient’s own plan says otherwise in writing. Where compounding stands after the shortage is at compounded GLP-1s after the shortage.
Medicare excludes weight-loss drugs by statute
Medicare Part D borrows the Medicaid list of drugs that may be excluded [42 U.S.C. 1395w-102(e)(2)(A)]. That list includes “agents when used for anorexia, weight loss, or weight gain” [42 U.S.C. 1396r-8(d)(2)(A)].
In April 2025, CMS said it was “not finalizing” its proposal to cover anti-obesity medications under Part D [CMS CY2026 final rule fact sheet]. CMS then created a separate, temporary program: the Medicare GLP-1 Bridge covers “certain GLP-1 drugs for weight management between July 1, 2026, and December 31, 2027,” and it “operates outside of the Part D coverage and payment flow” [CMS GLP-1 Bridge FAQs]. The program is built around approved brand products. Patients asking about Medicare should be pointed to it and to their plan. A compounded product is a separate question.
What patients are told, setting by setting
| Patient’s situation | Drug | Visit | What to say |
|---|---|---|---|
| Commercial insurance, compounded GLP-1 or peptide | Usually not covered | Self-pay in a cash program | “This program is self-pay. Your plan may cover a brand product. Check with your plan.” |
| Commercial insurance, brand GLP-1 | Depends on the plan, often with prior authorization | Depends on whether the practice bills insurance | Don’t promise coverage. Point them to the plan’s formulary. |
| Medicare | Part D excludes weight-loss use. The GLP-1 Bridge runs through December 31, 2027 for certain brand drugs | See the Medicare section below | “Medicare drug coverage excludes weight-loss drugs except through the CMS bridge program.” |
| Uninsured or choosing self-pay | Self-pay | Self-pay | Give the good faith estimate. |
| Has an HSA or FSA | Possibly eligible | Possibly eligible | “Ask your plan administrator. IRS rules allow it when a physician is treating a diagnosed condition.” |
HSA and FSA money can apply
IRS Publication 502 counts “amounts you pay to lose weight if it is a treatment for a specific disease diagnosed by a physician (such as obesity, hypertension, or heart disease)” as medical expenses. It also says that, except for insulin, a drug that “isn’t prescribed” doesn’t count [IRS Pub. 502].
So a prescribed medication for a diagnosed condition can be an eligible expense, and a general wellness purchase usually is not. The account administrator makes the call. Give patients an itemized receipt with the diagnosis-supported service and the prescription, and leave the eligibility decision to the administrator.
Self-pay patients are owed a good faith estimate
Under the No Surprises Act, providers must give uninsured and self-pay patients a good faith estimate of expected charges. The timing depends on how far ahead the service is scheduled. For a service scheduled at least three business days ahead, the estimate is due within one business day of scheduling. For a service scheduled at least ten business days ahead, or when the patient asks for an estimate, it is due within three business days [45 CFR 149.610].
If the final bill comes in substantially above the estimate, the patient can start a federal patient-provider dispute process. CMS sets the threshold per provider or facility [CMS, patient-provider dispute resolution]. Build the estimate into intake for every self-pay program, including telehealth, and keep a copy in the chart.
Medicare patients need a decision before the first visit
Cash-pay clinics often treat Medicare patients without thinking about it. Two federal rules matter.
- Physicians who have not opted out must submit claims to Medicare for covered services they furnish to beneficiaries, and may not charge for doing so [42 U.S.C. 1395w-4(g)(4)].
- Physicians who have opted out may sign private contracts with Medicare beneficiaries. The services are then “not covered services under Medicare” and Medicare pays nothing [42 CFR 405.405].
A drug Medicare excludes is not a covered service, so a cash price for the drug is not the issue. The visit can be. Decide with counsel how Medicare patients are handled in your program before you advertise to them. The broader point is at anti-kickback for cash-pay clinics: being cash-pay doesn’t put a clinic outside federal health care rules.
Telehealth parity laws don’t change the answer
Many states have telehealth laws for private insurers. Some require insurers to cover services delivered by telehealth if they would cover them in person. Others also require equal payment, and many add conditions [CCHP]. These laws govern how a plan treats services it already covers. They don’t require a plan to cover a compounded drug or a self-pay wellness program.
What this means for you
Tell patients the program is self-pay, in writing, before the first visit, and don’t speculate about their plan. Issue a good faith estimate to every self-pay patient on the federal timeline and keep it in the chart. Give itemized receipts so patients can pursue HSA or FSA reimbursement themselves. Decide how your program handles Medicare beneficiaries before you treat one. For program setup, see how to start a GLP-1 telehealth business, and for how MDside structures fees, see pricing.

Frequently asked questions
Does insurance cover compounded semaglutide or tirzepatide?
Usually not. Compounded drugs are made from bulk ingredients for one patient and generally fall outside insurer formularies. Medicare’s drug manual says bulk ingredients and compounded products generally don’t meet the definition of a Part D drug. Commercial plans vary, so treat compounded GLP-1s as self-pay unless a patient’s plan confirms coverage in writing.
Does Medicare cover weight-loss medication?
Medicare Part D excludes drugs used for weight loss by statute, and CMS declined in April 2025 to extend coverage. CMS separately runs a temporary GLP-1 Bridge for certain brand GLP-1s for weight management from July 1, 2026 through December 31, 2027, outside the Part D benefit. Patients should check eligibility with Medicare.
Can I use my HSA or FSA for a weight-loss program?
Often, if a physician is treating a diagnosed condition. IRS Publication 502 counts weight-loss costs as medical expenses when they treat a specific disease diagnosed by a physician, such as obesity or hypertension, and counts prescribed drugs. The account administrator decides eligibility, so ask for an itemized receipt.
Do telehealth clinics have to give self-pay patients a good faith estimate?
Yes. The No Surprises Act requires a good faith estimate for uninsured and self-pay patients. It is due within one business day when a service is scheduled at least three business days ahead, and within three business days when scheduled ten or more days ahead or when the patient requests one.
Can a cash-pay clinic treat Medicare patients?
It can, but the rules depend on the physician’s Medicare status. A physician who has not opted out must submit claims for covered services to Medicare beneficiaries. A physician who has opted out may use private contracts, and Medicare then pays nothing. Settle the approach with counsel before treating Medicare patients.
