Does Medicare cover Mohs surgery?

The removal itself: yes. Mohs micrographic surgery is billed under its own dedicated CPT codes, and Medicare Part B covers it as a physician service when medically necessary — a real, unambiguous benefit, and a genuinely different story from the DME checklists this site tracks for other surgeries. The honest gap sits one step later: elective, purely cosmetic scar revision after the cancer is gone is excluded by the same federal statute that excludes any cosmetic-only procedure, and none of the three items on this hub's own recovery checklist has a Medicare billing code at all.

The fact

Mohs micrographic surgery (CPT codes 17311-17315) is a covered Medicare Part B physician service when medically necessary.

Per CMS's own Medicare Coverage Database, Billing and Coding Article A53883 (guidance for Local Coverage Determination L34961): 'CPT codes 17311-17315 are reserved for the surgeon who removes a lesion, prepares, and interprets the slides.' This is a physician-service billing code, not a DME/HCPCS equipment code — this site's own 68-code tracked coverage_status.json dataset (built for mobility and bathroom-safety equipment) doesn't include it, and was never meant to; the two datasets simply cover different kinds of Medicare benefits.

What isn't covered: scar revision for appearance alone

Medicare's general cosmetic-surgery exclusion — Social Security Act Sec. 1862(a)(10) — bars payment for cosmetic surgery outright. CMS's own Local Coverage Determination L39506, "Cosmetic and Reconstructive Surgery," spells out how that applies:

“Cosmetic surgery is performed to reshape normal structures of the body in order to improve the patient's appearance and self-esteem… Per the Medicare Benefit Policy Manual cosmetic surgery or expenses incurred in connection with such surgery, for the sole purpose of improving one's appearance, is not covered.”

— CMS Medicare Coverage Database, LCD L39506 (source)

The same LCD draws the line that matters here: “Corrective facial surgery will be considered cosmetic rather than reconstructive when there is no functional impairment present.” UCLA Dermatology's own Mohs post-operative materials mention that a Mohs surgeon is “also skilled in scar revision techniques using laser technology to enhance the appearance of scars if necessary” — a real option some patients pursue afterward. Whether Medicare pays toward it comes down to that same functional-impairment test: revision done purely to improve appearance sits on the excluded side; revision addressing a documented functional problem (for example, a scar that restricts movement or eyelid function) can sit on the covered side. That's a case-by-case clinical determination between you and your surgeon, not something this site can answer in general.

The recovery checklist: zero Medicare billing codes

Checked directly against this site's own 68-code Medicare dataset and general HCPCS coding references: none of the three items on this hub's recovery checklist carry a billing code at all.

Mohs recovery-checklist items with no HCPCS code in Medicare's fee schedule
ItemWhat we found
Small ice pack No HCPCS code — not billed as DME, the same finding this site's knee, hip, hernia, and facelift hubs all reach for ice/cold-therapy items.
Head-elevation wedge No HCPCS code exists for a sleep-positioning wedge — same finding as this site's knee, mastectomy, and facelift hubs.
Silicone scar tape / sheet No HCPCS code — a cosmetic/scar-management product, not DME, same finding as this site's thyroidectomy hub.

This isn't a data gap — it's the expected pattern. Mohs surgery isn't a mobility-limiting procedure the way a joint replacement is, so its recovery basket was never built around DME-billed equipment the way a walker or a hospital bed was. See the full recovery checklist →

Why this hub's coverage story looks different from this site's other hubs

Most hubs on this site track a checklist of DME (durable medical equipment) items against Medicare's HCPCS Level II code set — walkers, raised toilet seats, hospital beds — and the honest finding is usually thin or mixed coverage. Mohs surgery is different in kind: the procedure itself is billed under CPT (physician-service) codes, an entirely separate Medicare billing system from HCPCS DME codes. That's why this page can lead with a genuine yes on the surgery, even though the follow-up equipment story is the same $0-across-the-board finding as everywhere else on this site.

This page explains what CMS's own published billing guidance and coverage determinations show — it isn't a coverage determination for your specific claim. A Medicare Advantage plan or supplemental insurance can set different rules than the Original Medicare figures discussed here; confirm your own situation with your plan or provider before you buy or schedule anything.
