Mohs surgery costs around $2,500 on average for the procedure itself, but the total bill can range widely depending on the complexity of your case. A straightforward removal on the trunk might cost under $1,500, while a multi-stage procedure on the face followed by reconstructive repair can push costs well above $5,000. Understanding what drives the price helps you anticipate your out-of-pocket expense before you schedule.
What Makes Up the Total Bill
The final number on your bill isn’t a single charge. It’s built from several separate components, each billed under its own code. The surgeon’s professional fee covers the actual removal and microscopic examination of tissue. If the procedure happens in a hospital-affiliated office or ambulatory surgery center, a facility fee covers the use of the space, equipment, nursing staff, and supplies. These facility fees can add hundreds or even thousands of dollars beyond what the surgeon charges, and they vary significantly depending on whether you’re treated in a private dermatology office versus a hospital outpatient department.
Then there’s reconstruction. After the cancer is fully removed, the wound needs to be closed. A simple side-to-side closure with stitches is the least expensive option and is often included in the surgeon’s fee or billed modestly. But many Mohs procedures, especially on the face, require more involved repairs.
Why Reconstruction Often Doubles the Price
The location and size of the wound after removal determines what kind of repair you need, and this is frequently the biggest variable in total cost. Simple flap procedures, where nearby skin is repositioned to cover the wound, generally cost $2,000 to $5,000. More complex microsurgical flaps that involve reconnecting blood vessels can run $5,000 to $12,000 or more due to the specialized skill and longer operating time required. Research on Mohs billing has found that needing a flap or graft adds roughly $1,800 to the total fee compared to cases that don’t require one.
If a plastic surgeon handles the reconstruction rather than the Mohs surgeon, you’ll receive a separate bill from that provider. This is common for wounds in cosmetically sensitive areas like the nose, eyelids, or lips.
Factors That Push Costs Higher
Three variables consistently predict a higher total bill: where the tumor is located on your body, how large it is, and how many stages the surgeon needs to achieve clear margins.
Tumors on the head, neck, hands, feet, or genitalia are billed at higher rates than those on the trunk or limbs. These areas involve more complex anatomy, with important nerves, cartilage, and blood vessels nearby, so the procedure demands greater precision and the billing codes reflect that. Tumors larger than about 10 millimeters (roughly the width of a pencil eraser) are independently associated with higher fees as well.
The number of stages is the factor most unique to Mohs. During the procedure, the surgeon removes a thin layer of tissue, maps it, and examines it under a microscope while you wait. If cancer cells are still present at any margin, another layer is taken from that specific area. Each additional stage adds to the bill, typically $75 to $150 per stage at Medicare rates, though commercial insurance and self-pay rates can be higher. Most cases require one to three stages, but aggressive or recurrent cancers sometimes need more.
Insurance Coverage and Out-of-Pocket Costs
Mohs surgery is a medically necessary cancer treatment, not a cosmetic procedure, so most health insurance plans cover it. Medicare, Medicaid, and private insurers typically pay for the procedure when it meets established guidelines, which generally means it’s being used for skin cancers in areas where tissue preservation matters or for tumors with aggressive features.
Your actual out-of-pocket cost depends on your plan’s deductible, copay, and coinsurance structure. If you haven’t met your annual deductible, you could owe the full negotiated rate up to that threshold. After meeting your deductible, you’d typically pay a percentage (often 10% to 30%) of the remaining charges until hitting your out-of-pocket maximum. For someone with a $2,000 deductible and 20% coinsurance, a $4,000 total bill might result in roughly $2,400 out of pocket if none of the deductible has been met.
Ask your surgeon’s billing office for the anticipated CPT codes before your procedure. The primary codes are 17311 for a first-stage removal on the head, neck, hands, feet, or genitalia, and 17313 for the trunk, arms, or legs. Giving these codes to your insurance company lets you get a more accurate estimate of your responsibility.
How Mohs Compares to Standard Excision
If you’re wondering whether Mohs is more expensive than a standard surgical excision, the answer is more nuanced than you might expect. A JAMA Dermatology analysis found that Mohs and traditional excision were essentially cost-comparable when looking at the full picture. The initial Mohs procedure cost averaged $937 compared to $944 for excision when the excision margins came back clear on the first attempt.
The key difference is what happens when margins aren’t clear. Standard excision sends tissue to a separate lab, and results take days. If the pathology report shows cancer remaining at the edges, you need a second procedure. Mohs checks margins in real time, so you leave the office the same day knowing the cancer is fully removed. When frozen section analysis was added to standard excision (to check margins immediately, similar to Mohs), the excision cost actually jumped to $1,399 versus $956 for Mohs. In other words, Mohs delivers higher cure rates, often above 99% for primary basal cell carcinoma, without necessarily costing more when you account for the risk of repeat procedures.
Ways to Reduce Your Costs
Where you have the procedure matters financially. A Mohs surgery performed in a freestanding dermatology office typically costs less than the same procedure in a hospital outpatient department, because you avoid the hospital facility fee. If your surgeon operates out of multiple locations, ask whether a non-hospital site is available.
If you’re uninsured or facing high out-of-pocket costs, ask about payment plans or self-pay discounts. Many dermatology practices offer reduced rates for patients paying directly, since they avoid the administrative cost of insurance billing. Getting an itemized estimate in advance, including the surgery, pathology, and anticipated reconstruction, prevents surprises and gives you a chance to compare costs across providers.
