How Much Does Mohs Surgery Cost?

Mohs micrographic surgery is widely considered the gold standard for treating certain skin cancers — particularly basal cell and squamous cell carcinomas in cosmetically sensitive or high-risk areas. The cost of Mohs surgery typically ranges from an estimated $1,500 to $5,000 or more, depending on the tumor’s location, how many tissue layers must be removed, and whether reconstructive repair is needed afterward. While that figure may seem steep for what is usually an outpatient procedure, insurance almost always covers this medically necessary cancer treatment, and its very high cure rate makes it cost-effective compared with alternatives that carry higher recurrence risk. All prices in this guide are estimates as of early 2026 that vary widely by region and case — treat them as ballparks, not quotes.

Skin cancer treatment costs fit into the broader picture of medical expenses in America. Our complete guide to healthcare costs explains how insurance determines what you will actually pay for any procedure.

Average Cost of Mohs Surgery

Mohs surgery pricing has several components, each billed separately using specific CPT codes. Based on Medicare fee-schedule structure and dermatologic surgery billing standards, here is roughly what each phase tends to cost as of early 2026. Every band below is an estimate that varies by region, payer, and case.

The first stage of Mohs (CPT 17311) — which includes the tissue excision, precise mapping, immediate on-site lab processing, and microscopic examination of the surgical margin — is often estimated at $600 to $1,200. Each additional stage (CPT 17312), needed when cancer cells are found at a margin, may add roughly $200 to $500 per stage. Most Mohs procedures require one to three stages, though complex, recurrent, or aggressive tumors can require more to reach clear margins.

Wound repair or reconstruction adds meaningful cost and depends heavily on the defect’s size and location. A simple side-to-side closure with sutures (CPT 12031–12057) might run an estimated $200 to $500. A skin flap — where adjacent tissue is mobilized to fill the wound (CPT 14000–14302) — is often estimated at $800 to $2,500 and requires more surgical skill and time. A skin graft harvested from another site (CPT 15100–15261) may run $1,000 to $3,000. The nose, eyelids, ears, and lips tend to require the most complex reconstructions because of limited surrounding tissue and high cosmetic stakes.

Total costs for a straightforward case with one to two stages and simple closure often fall in an estimated $1,500 to $2,500 range. Moderate cases requiring two to three stages and a flap reconstruction may run $2,500 to $4,000, and complex cases with multiple stages and extensive reconstruction can reach $4,000 to $6,000 or more. According to the Skin Cancer Foundation, Mohs surgery achieves cure rates up to about 99% for primary basal cell carcinomas and up to about 97% for recurrent tumors, which is part of why it is considered cost-effective relative to the alternative of recurrence and retreatment.

What Mohs Surgery Is (and Who Performs It)

It is worth being clear on what you are paying for. Mohs is not a cosmetic procedure — it is surgery to remove certain skin cancers while sparing as much healthy tissue as possible. The surgeon removes the visible tumor plus a thin layer of surrounding tissue, maps it, and examines the margins under a microscope on-site; if cancer remains at any edge, another precisely targeted layer is removed, and the process repeats until margins are clear. This is why it has such high cure rates for appropriate tumors.

Mohs is performed by a fellowship-trained Mohs surgeon — typically a dermatologist who completed additional subspecialty training in the technique and in reconstruction. Choosing a fellowship-trained Mohs surgeon (for example, a member of the American College of Mohs Surgery) is one of the most important quality decisions you can make. Because Mohs treats cancer, delaying or skipping treatment to save money carries real risk; the cost strategies below are about paying less for necessary care, not avoiding it.

Insurance Coverage for Mohs Surgery

Mohs surgery is covered by virtually all insurance plans — Medicare, Medicaid, and private insurance — when performed for diagnosed skin cancer. It is considered the standard of care for cancers in several situations: cosmetically and functionally sensitive areas (face, ears, hands, feet, genitals), recurrent cancers that returned after previous treatment, large or poorly defined tumors, aggressive histologic subtypes (such as morpheaform, infiltrative, or micronodular basal cell carcinoma), and cancers where tissue conservation is critical (near the eyes, nose, mouth).

Prior authorization is typically not required for Mohs on skin cancers in those locations and situations — most insurers recognize it as appropriate and process claims without pre-approval. However, if the cancer is in a location where standard excision would usually suffice (such as the trunk or an extremity away from a joint), your insurer may want documentation justifying Mohs over standard excision. Your Mohs surgeon can provide this based on tumor type, size, histology, and proximity to important structures.

Under Medicare Part B, Mohs surgery is generally covered at 80% of the Medicare-approved amount after the annual Part B deductible, which is $283 in 2026 (up from $257 in 2025). On that basis, your 20% coinsurance on, say, a $2,500 approved amount would be roughly $500, plus the deductible if you have not already met it for the year. A Medigap supplement such as Plan G typically covers the Part B coinsurance, which can bring your share close to $0 after the deductible. Many Medicare Advantage plans instead use flat copays for outpatient procedures — often in the low hundreds of dollars — which may result in lower out-of-pocket costs than Original Medicare alone. Exact amounts depend on your plan, and Medicare figures change annually, so verify current numbers.

Your Out-of-Pocket Cost With Private Insurance

With private insurance, your cost follows your standard plan structure. If you have already met your annual deductible, you will pay your coinsurance rate — commonly 10% to 30% of the allowed amount. On a plan with 20% coinsurance and a met deductible, a $3,000 Mohs procedure might cost you about $600. If you have not met your deductible, more of the cost comes from your pocket until you cross that threshold.

For example, a patient with a $2,000 deductible who has had no other medical expenses that year might pay roughly $2,000 (deductible) plus 20% of the remaining $1,000 ($200) on a $3,000 procedure, totaling about $2,200. If that same patient had already put $1,500 toward the deductible earlier in the year, the cost could drop to about $500 (remaining deductible) plus 20% of $2,500 ($500), totaling roughly $1,000. These are illustrations, not quotes — your plan’s allowed amounts and rules determine the real figure.

Because skin cancers often require ongoing surveillance — dermatology visits every few months to a year, biopsies of suspicious lesions, and sometimes multiple treatment procedures — patients who undergo Mohs may accumulate enough medical expenses to approach their out-of-pocket maximum during the plan year. If you need additional procedures, it can help to time them strategically within the same plan year to make the most of costs already applied toward your out-of-pocket maximum.

If You’re Uninsured or Paying Cash

If you do not have insurance, ask the practice for a Good Faith Estimate before treatment. Under the No Surprises Act, uninsured and self-pay patients are generally entitled to a written estimate of expected charges for scheduled care, and if the final bill comes in substantially higher you may be able to use the patient-provider dispute process. Also ask about self-pay or prompt-pay discounts and payment plans; many dermatology practices offer them. Because Mohs treats cancer, the priority is getting timely, high-quality care — but these tools can make necessary treatment more affordable.

Factors That Affect Mohs Surgery Pricing

Number of Stages

Each stage adds time, lab processing, and cost. The surgeon removes a thin layer of tissue, maps it with colored dyes, processes it in the on-site lab (frozen-section technique), and examines every edge under the microscope. If cancer cells appear at a margin, the next stage targets exactly where cancer remains. Most procedures finish in one to three stages, but some require more — particularly for tumors that extend deeper or wider than expected, or for aggressive subtypes that grow in finger-like projections.

Location on the Body

Tumors on the nose (especially the tip, ala, and dorsum), eyelids, ears, lips, and around the eyes require more delicate excision because of thin skin, complex contours, and proximity to critical structures like the tear-drainage system, cartilage, and facial nerve branches. These areas also have limited surrounding tissue for closure, often requiring flap reconstruction rather than simple suturing. A Mohs procedure on the nasal tip with flap reconstruction can cost an estimated $1,500 to $2,000 more than a similar-sized tumor on the forehead that closes with sutures alone.

Reconstruction Complexity

The choice of closure depends on the size and shape of the wound (defect) after all cancer is removed. Simple side-to-side closures are least expensive. Advancement, rotation, or transposition flaps require more skill, planning, and time. Full-thickness skin grafts harvested from behind the ear, the collarbone area, or the inner arm are the most expensive option. In some cases the Mohs surgeon performs the reconstruction in the same session; in others, a plastic, oculoplastic, or facial-plastic surgeon handles the repair separately, adding a distinct professional fee.

How to Save on Mohs Surgery

Mohs is not a procedure to comparison shop the way you might for elective imaging — you need a skilled fellowship-trained specialist, and delaying cancer treatment carries risk — but you can take practical steps to limit costs. First, confirm that your Mohs surgeon is in-network with your plan. If a separate surgeon handles reconstruction, verify their network status too. Out-of-network providers can generate bills that do not count toward your in-network out-of-pocket maximum, dramatically increasing your exposure.

Office-based Mohs surgery — how the large majority of Mohs procedures are performed — is usually significantly less expensive than hospital-based Mohs. The American Academy of Dermatology notes that office-based procedures avoid hospital facility fees entirely, which can save a substantial amount. If your dermatologist refers you to a hospital-based program, ask whether an office-based, fellowship-trained Mohs surgeon is available in your area.

If you are facing multiple skin cancer treatments in the same year — common for patients with significant sun exposure — coordinating procedures within a single plan year maximizes the benefit of your deductible and out-of-pocket maximum. After you meet your out-of-pocket maximum, additional covered procedures and surveillance visits are generally paid at 100%, removing cost as a barrier to thorough follow-up. And if you are uninsured, request a Good Faith Estimate and ask about self-pay discounts before treatment.

Frequently Asked Questions

Does Mohs surgery require anesthesia?

Mohs is performed under local anesthesia — similar to numbing at the dentist. The area around the tumor is numbed, and you stay awake and comfortable throughout. General anesthesia or IV sedation is almost never required, which avoids separate anesthesia fees and their associated risks. The local anesthesia is included in the surgical fee.

How long does Mohs surgery take?

Each stage takes roughly 20 to 30 minutes for excision and about 45 to 60 minutes for tissue processing and microscopic examination. A single-stage case may take two to three hours total including preparation, excision, lab work, margin review, and closure. Multi-stage cases can last much of the day, since each additional stage adds processing and review time. Plan to be at the office for several hours, and bring something to occupy the waits between stages.

Is Mohs surgery more expensive than standard excision?

Usually yes, upfront. Standard excision (excision plus pathology) is often estimated at $500 to $1,500, less than Mohs. However, Mohs achieves higher cure rates than standard excision in high-risk areas, and a recurrence after standard excision can lead to additional procedures, more tissue loss, more complex reconstruction, and sometimes more extensive surgery — often costing more in total. For appropriate tumors and locations, Mohs tends to be the more cost-effective choice over a multi-year horizon.

Will I need plastic surgery after Mohs?

Most wounds after Mohs are repaired by the Mohs surgeon in the same visit using direct closure, a flap, or a graft; Mohs surgeons receive extensive reconstruction training during fellowship. For very large defects, defects in especially complex locations (such as full-thickness eyelid or nose defects), or when the patient prefers a specialist for the repair, a plastic or oculoplastic surgeon may perform the reconstruction separately, which adds a professional fee.

The Bottom Line

As of early 2026, Mohs surgery is commonly estimated at $1,500 to $5,000 or more, depending on the number of stages and the type of reconstruction. Insurance covers it as medically necessary for diagnosed skin cancer, so your actual out-of-pocket cost is set by your deductible and coinsurance — often somewhere from a few hundred to a couple thousand dollars, depending on your plan and where you are in the year. Choose an in-network, fellowship-trained Mohs surgeon, confirm any reconstructive surgeon is also in-network, ask for a Good Faith Estimate if you are uninsured, and coordinate multiple treatments within the same plan year when possible. All prices here are estimates that vary widely — verify coverage and costs with your provider and insurer, and never delay skin cancer treatment to shop on price.
