What Medicare Covers for Dermatology: Skin Cancer, Biopsies, and What Is Excluded

Skin cancer is the most common cancer in the United States, and Medicare-age adults are at significantly elevated risk due to cumulative sun exposure. Medicare's dermatology coverage is driven by medical necessity, procedures that diagnose or treat skin conditions are covered; preventive and cosmetic services are generally not. Understanding which side of that line your care falls on helps you use Medicare correctly and avoid unexpected bills for uncovered services.

Bryce's Take

The skin cancer screening situation is one of the more confusing coverage gaps in Medicare. Annual physical exams are not covered, and neither is a dedicated annual skin cancer screening as a standalone preventive dermatology visit. What IS covered is the dermatologist visit for evaluation of a specific lesion, and the biopsy or treatment of anything suspicious. If you have a concerning spot, going to dermatology for evaluation of that specific finding is a covered Part B service. The gap is routine "check everything" annual screenings, not evaluation of actual concerns.

Medically necessary dermatology visits

When you see a dermatologist for evaluation of a specific lesion, suspicious growth, new or changing mole, rash, or other skin concern that may indicate a medical condition, the visit is covered under Medicare Part B as a medically necessary specialist visit. The evaluation and management service, any diagnostic procedures performed during the visit, and subsequent treatment are covered with standard Part B cost-sharing. This applies to evaluation of potential melanoma, basal cell carcinoma, squamous cell carcinoma, inflammatory conditions, infections, and other medically significant skin conditions.

Skin biopsies and tissue removal

Biopsies of suspicious skin lesions are covered under Medicare Part B. The biopsy procedure, pathology laboratory analysis, and physician interpretation of results are all covered when medically indicated. Removal of premalignant lesions, actinic keratoses, which are rough, scaly patches caused by sun damage that can progress to squamous cell carcinoma, is covered under Part B. Surgical removal of benign skin lesions such as cysts or lipomas may be covered when medically necessary and documented as symptomatic rather than cosmetic.

Mohs surgery for skin cancer

Mohs micrographic surgery, a specialized technique for removing skin cancer that examines cancer margins in real time, is covered under Medicare Part B. Mohs surgery is typically used for basal cell and squamous cell carcinoma in difficult locations such as the face, ears, and hands where tissue conservation is important, or for aggressive tumors. The Mohs surgeon performs the procedure in an outpatient surgical setting, and the procedure may involve multiple stages in a single session. Standard Part B cost-sharing applies.

What Medicare does not cover in dermatology

Cosmetic procedures are specifically excluded from Medicare coverage regardless of where they are performed. This includes Botox injections for wrinkle reduction, cosmetic fillers, cosmetic laser treatments, cosmetic removal of benign spots or moles that cause no medical symptoms, and any procedure performed primarily for aesthetic rather than medical purposes. Routine preventive skin cancer screenings, an annual full-body skin exam performed by a dermatologist specifically for cancer screening when you have no concerning lesions, are not covered as a standalone preventive service under Original Medicare.

Questions about whether a specific dermatology procedure is covered by your plan?

The medically necessary versus cosmetic distinction determines whether Medicare pays. If you are unsure which category your procedure falls into, a quick conversation can clarify before your appointment.

The Botox exception: covered medical uses

Botox is covered by Medicare when used for specific medical conditions, not for cosmetic purposes. Covered medical uses include hyperhidrosis (excessive sweating) when it is severe and documented to be unresponsive to topical treatments, cervical dystonia, blepharospasm (uncontrolled eyelid spasms), spasticity, and certain chronic migraine diagnoses. When Botox is administered for these covered medical conditions with appropriate physician documentation, Medicare Part B covers the injection at standard cost-sharing. The same injection administered for facial aesthetics is not covered.

Dermatology under Medicare Advantage

Medicare Advantage plans cover medically necessary dermatology to the same extent as Original Medicare. Some Advantage plans add supplemental benefits such as additional wellness screenings or discounts on cosmetic services. Prior authorization is common for Mohs surgery and other dermatological procedures under Advantage plans. If you need Mohs surgery or a complex dermatological procedure, verify your plan's prior authorization requirements before scheduling.

Frequently asked questions

Does Medicare cover an annual skin cancer screening from a dermatologist?

A dedicated annual skin cancer screening from a dermatologist is not a separately covered preventive service under Original Medicare. However, skin assessment is included in the Annual Wellness Visit with your primary care physician. If your primary care physician identifies a concerning lesion during any visit and refers you to a dermatologist, that dermatology visit is a covered medically necessary evaluation.

What if I have a mole that looks different but does not bother me?

Evaluation of a changing or suspicious mole is a medically necessary dermatology visit regardless of whether it causes symptoms. "Looks different" or "is changing" is a medical reason for evaluation, not a cosmetic concern. This visit is covered under Part B.

Does Medicare cover treatment for psoriasis or eczema?

Yes. Treatment for inflammatory skin conditions including psoriasis, eczema, and similar conditions is medically necessary and covered under Medicare Part B for physician services and under Part D for prescription medications. Biologic medications for severe psoriasis (administered by injection) may be covered under Part B or Part D depending on administration method.

Can I use my Medicare Advantage vision benefit for eye conditions evaluated during a dermatology visit?

Dermatology and ophthalmology are separate specialties with separate coverage. Skin conditions around the eyes are treated by dermatologists under Part B coverage. Eye conditions are evaluated by ophthalmologists under Part B for medical conditions or by optometrists for routine vision care.
