Medicare's Coverage of Dermatology Cancer Screening

Medicare Part B covers skin cancer screening when your doctor orders it as part of your medical care — but only if you have symptoms, a personal history of skin cancer, or a family history that puts you at higher risk. Medicare does not cover routine screening for people with no signs or risk factors. If your dermatologist finds a suspicious spot during an office visit, the exam and any biopsy are covered. If the spot turns out to be cancer, treatment is covered under Part B.

The coverage applies to the screening itself, the pathology work if tissue is removed, and follow-up care. You pay your Part B deductible (which varies year to year) and then 20 percent of the Medicare-approved amount for the visit. If your dermatologist is in-network with Medicare, you typically pay less out of pocket.

Key Takeaways

  • Medicare Part B covers skin cancer screening and biopsies when ordered by your doctor for medical reasons, not for routine prevention in people with no risk factors.
  • You pay your Part B deductible and 20 percent coinsurance after that, unless your dermatologist accepts Medicare assignment.
  • Treatment of confirmed skin cancer — including removal, Mohs surgery, and follow-up visits — is covered under Part B.
  • Medigap or Medicare Advantage plans may cover some or all of your coinsurance and deductible, depending on your plan.

When Medicare Covers Screening Versus When It Does Not

The line between covered and not covered depends on why you are seeing the dermatologist. If you have a visible lesion, a history of melanoma or other skin cancer, or a family history of skin cancer, Medicare considers screening medically necessary and covers it. If you are going in for a routine full-body skin check with no symptoms or risk factors, Medicare may not cover the visit itself, though any treatment of a lesion found during that visit would be covered.

Some dermatologists bill the screening and the treatment separately. If the screening portion is deemed not medically necessary, you may receive a notice that you owe that part of the bill. This is where knowing your own risk factors matters: if you have had a skin cancer before or have a family member who has, mention it to your dermatologist before the visit so it is documented in your chart.

What Happens After a Biopsy or Diagnosis

Once a dermatologist removes tissue for biopsy, the pathology lab analyzes it and sends a report to your doctor. Medicare covers the lab work. If the result is skin cancer, your treatment options — whether that is a straightforward excision, Mohs micrographic surgery, cryotherapy, or referral to an oncologist — are all covered under Part B, with you paying 20 percent coinsurance after your deductible.

Mohs surgery, which is often used for basal cell and squamous cell carcinomas on the face or other sensitive areas, is covered by Medicare. The procedure involves removing skin layer by layer and examining each under a microscope to may support all cancer is gone. You pay the standard 20 percent coinsurance for this procedure.

How Your Supplemental or Advantage Plan Affects Your Out-of-Pocket Cost

If you have a Medigap (supplemental insurance) plan, it typically covers your Part B coinsurance and deductible, which means you pay little to nothing out of pocket for dermatology visits and biopsies. The specific coverage depends on which Medigap plan you chose when you first enrolled.

If you have a Medicare Advantage plan instead of Original Medicare plus Medigap, your coverage works differently. Advantage plans have their own networks and copays. Some Advantage plans cover dermatology with a copay (often $20 to $50 per visit), while others require you to meet a deductible first. Check your plan's formulary or call the plan directly to find out what you owe for a dermatology visit.

Finding a Dermatologist Who Accepts Medicare

Not all dermatologists accept Medicare, and some accept it only for certain procedures. Before you schedule, call the office and ask whether they accept Medicare assignment. If they do, they agree to accept Medicare's approved amount as payment in full (after you pay your deductible and coinsurance). If they do not accept assignment, they can charge you more, and you may have to pay upfront and seek reimbursement yourself.

You can search for in-network dermatologists through Medicare.gov's provider search tool. Enter your zip code and select "dermatology" to see who is accepting Medicare patients in your area. If you have a Medicare Advantage plan, use your plan's provider directory instead, since the networks differ.

What to Bring and How to Prepare

Bring your Medicare card and any photo ID to your dermatology appointment. If you have had skin cancer before or have a family history, bring that information in writing or be ready to describe it to the intake staff. This documentation helps may support Medicare covers the visit as medically necessary screening rather than routine prevention.

If you are concerned about a specific spot on your skin, point it out to your doctor at the start of the visit. If you have multiple spots you want checked, let your dermatologist know so they can document the medical reason for examining each one. This protects you from receiving a bill later for portions of the visit Medicare deemed unnecessary.

Frequently Asked Questions

Does Medicare cover annual skin cancer screening if I have no symptoms?

Not routinely. Medicare covers screening only when there is a medical reason — such as a visible lesion, personal history of skin cancer, or significant family history. If you want routine screening with no risk factors, you would likely pay out of pocket, though any treatment of a lesion found during that visit would be covered.

What if my dermatologist says a spot is not cancer but I want it removed anyway?

If the spot is benign (not cancerous), removal is usually considered cosmetic and not covered by Medicare. However, if the spot is irritated, bleeding, or causing you physical discomfort, your dermatologist may be able to document a medical reason for removal, which could make it covered. Ask your dermatologist whether the reason for removal qualifies as medically necessary.

Will I get a bill if Medicare denies the screening visit?

You may receive a notice that Medicare denied the screening portion of your visit. If your dermatologist did not get advance notice that Medicare might not cover it, you should not be billed. If you receive a bill, contact your dermatologist's office and ask them to appeal or adjust the charge. You have the right to dispute it.

Does Medicare cover dermatology if I have a Medicare Advantage plan?

Yes, but the coverage and cost depend on your specific plan. Most Advantage plans cover dermatology with a copay, but some require a deductible first or limit the number of visits per year. Check your plan documents or call your plan's customer service to find out your exact coverage before scheduling.

What if my dermatologist is not in my Medicare network?

If you see an out-of-network dermatologist, you may pay more out of pocket. Some dermatologists who do not accept Medicare assignment can charge up to 15 percent more than Medicare's approved amount. Ask the office about their fees before your visit, and consider using an in-network provider to keep costs predictable.
