Medical vs Cosmetic Dermatology: What Medicare and Insurance Cover

What Medicare says about cosmetic treatments, what accepting Medicare assignment means, and what to ask a Medicare Advantage or private plan first.

Dermatology covers two kinds of care. Medical dermatology diagnoses and treats skin, hair and nail conditions and skin cancer. Cosmetic dermatology covers treatments chosen mainly to change how skin looks. Many practices offer both. The difference matters most when the bill comes, because Medicare and most health plans pay for care to diagnose or treat a condition, and usually not for care that is only about appearance. This guide covers what Medicare says, what "accepts Medicare assignment" means and what to ask any plan before you book.

What Medicare covers and does not cover

Medicare Part B covers medically necessary services. On its Part B page, Medicare defines these as services or supplies that meet accepted standards of medical practice to diagnose or treat a medical condition.

Cosmetic care is a different story. Medicare's page on cosmetic surgery says Medicare generally does not cover it. The exceptions it lists are surgery needed because of an accidental injury, surgery to improve the function of a malformed body part, and breast reconstruction after a mastectomy for breast cancer. If a service is not covered, you pay all of the cost.

The same Medicare page lists some services that are sometimes, but not always, treated as cosmetic, and that usually need prior authorization. Two can come up in skin and facial care:

• Botulinum toxin injections. Medicare describes these in the context of muscle disorders such as spasms.
• Blepharoplasty, eyelid surgery to remove excess tissue.

The provider sends the prior authorization request. Whether a treatment is covered depends on why it is done and how it is documented, so the same procedure may be covered for one patient and not another.

Gray areas to ask about

Some visits mix medical and cosmetic care. For example, a single appointment might include an exam of a spot your doctor is concerned about and a cosmetic treatment you asked for. Ask the office before the visit:

• Which parts of today's visit will be billed to my insurance or Medicare, and which will I pay for myself?
• If a service may not be covered, can you tell me in writing before you do it?
• Does this treatment need prior authorization, and who will request it?
• If a sample is sent to a lab, will the lab bill me separately?

What "accepts Medicare assignment" means

Medicare explains this on its page about whether a provider accepts Medicare. In plain terms, as of 2026:

• Accepts assignment (participating). The provider agrees to charge you only the Medicare deductible and coinsurance, must send the claim to Medicare and cannot charge you for sending it. Medicare says most providers accept assignment, and your out-of-pocket costs may be lower.
• Does not accept assignment (non-participating). The provider may still take Medicare patients and may accept assignment case by case. You might have to pay the full amount at the visit. The provider can charge more than the Medicare-approved amount, but medicare.gov says the charge cannot be more than 15% above it. This cap is called the limiting charge.
• Opted out. Medicare will not pay for services from a provider who has opted out, except in emergencies, even if the service would normally be covered. You would sign a private contract and pay the provider directly. Medicare says opt-out lasts at least 2 years.

Some listings on this site show a Medicare assignment value from the CMS Doctors and Clinicians file. In the CMS data dictionary, "Y" means the clinician accepts the Medicare-approved amount as payment in full, and "M" means the clinician may accept assignment. An "M" is a reason to ask about your specific visit. You can also check a clinician in Medicare's Care Compare tool. Assignment applies to covered services; it does not make a cosmetic service covered.

Medicare Advantage plans

If you have a Medicare Advantage plan, the rules are the plan's. Medicare's comparison of Original Medicare and Medicare Advantage says that with Original Medicare you can use any doctor who takes Medicare and in most cases do not need a referral to see a specialist. With Medicare Advantage, you may need to use doctors in the plan's network, you may need a referral to see a specialist, and you may need prior authorization for certain services.

A dermatologist who accepts Original Medicare is not automatically in your Advantage plan's network. Before booking, call the number on your plan card and ask:

• Is this dermatologist, at this location, in my plan's network?
• Do I need a referral from my primary care provider?
• Does the procedure I may need require prior authorization?
• What will my copay or coinsurance be for a specialist visit?

Private insurance and Medicaid

Employer and individual health plans and state Medicaid programs set their own coverage rules, so check with the plan before you assume a treatment is covered or not. The questions above work for any plan: Is the clinician in network? Is a referral needed? Is prior authorization needed? What will I owe? This directory does not list which plans a practice takes, so confirm with the plan and the office.

Telehealth

Some listings show a telehealth indicator. In the CMS file, this means Medicare fee-for-service claims show that the clinician offers telehealth by video or audio. Medicare's telehealth page says that through December 31, 2027, Medicare covers telehealth services you get from anywhere in the US, including your home, and that for most telehealth services you pay the same as for an in-person visit. Ask the office whether your concern can be handled by video or needs an in-person exam.

Before you pay for cosmetic care

Because cosmetic care is usually self-pay, ask for a written estimate that lists every charge, and ask who will perform the treatment and what that person's license is. Our guide on checking a dermatologist's license and board certification shows how to verify credentials yourself. For skin checks, see preparing for a skin exam.
