Most common skin cancers are treated with a short procedure under local anesthetic, often in a dermatologist's office. The cost depends on factors that only become clear on the day: how many layers of tissue need to come off, how the wound is closed, and whether a second surgeon is involved. This guide explains how Mohs surgery, standard excision and reconstruction are billed. It also explains why skin cancer is one of the weakest cases for medical travel.
Key takeaways
- Mohs surgery removes cancer one thin layer at a time, checking each layer under a microscope while you wait. Its cost depends on how many layers it takes.
- Closing the wound can cost as much as removing the cancer, especially on the face. Grafts and flaps, or a second surgeon, change the bill.
- Skin cancer treatment is usually medically necessary, so for insured patients the comparison is your deductible and coinsurance, not a cash price.
- Diagnosis, wound checks and lifelong skin surveillance happen where you live, so travel rarely saves money here.
The treatment options and how each is billed
Mohs surgery
In Mohs surgery the surgeon removes the visible cancer and a thin layer of tissue, then examines that layer under a microscope. If cancer cells remain at the edges, another layer is removed from that spot, and so on until the edges are clear. Memorial Sloan Kettering's patient guide says the procedure uses a local anesthetic only, and that patients may be there for several hours or the whole day, depending on how many layers are needed (MSK, 2023).
For cost, the point is that the number of layers isn't known in advance. A quote that covers "Mohs surgery" may assume a particular number of layers, with more priced on top. Ask how your quote handles extra layers before the day.
Standard excision
The surgeon cuts out the lesion with a margin of normal skin, closes the wound, and sends the tissue to a pathology lab. The pathology is often billed separately from the surgery. If the report shows cancer at the edge, you may need a second procedure, which is a second bill.
Superficial treatments
Some early or superficial cancers can be treated with prescription creams, scraping and cautery, or light-based therapy. These usually cost less per treatment but may need repeat visits. Whether they suit you is a decision for your dermatologist.
Closing the wound: often the bigger cost
MSK's guide says wounds after Mohs may be closed with stitches, skin glue or a skin graft, that some heal without repair, and that if a plastic surgeon closes the wound, this has to be planned ahead (MSK, 2023). On a cost quote, those options look very different:
| Closure | Typical situation | Cost implications |
|---|---|---|
| Healing on its own | Small or shallow wounds in suitable locations | Lowest procedure cost, more wound care at home |
| Simple stitched closure | Wounds that close in a line | Often part of the main procedure price; check |
| Flap (moving nearby skin) | Larger wounds on the face, nose, ears or lips | A separate repair, priced by size and complexity |
| Graft (skin from elsewhere) | Wounds too large for a flap | Adds a donor site and more wound care |
| Closure by a plastic surgeon | Complex facial repairs | A second surgeon's fee, possibly a different facility and anesthesia |
Where the cancer is matters a lot. A small lesion on the back can often be removed and stitched in one short visit. A similar lesion on the side of the nose may need careful tissue-sparing removal and a flap. Ask your dermatologist which closure they expect and who does it, so you can get a price for each part.
Office or hospital: the setting changes the U.S. bill
Many skin cancer procedures happen in dermatology offices. Some, especially complex reconstructions or surgery under sedation, happen in hospital outpatient departments or surgery centers, which add a facility fee. If you're self-pay, ask whether the office can do your procedure and request Good Faith Estimates from the surgeon, the pathology lab and any second surgeon. Our setting cost guide explains why the same procedure can cost very different amounts in different places.
If you're uninsured in the U.S.
An uninsured patient is comparing cash prices, so the bill structure matters even more. Ask the dermatology office for a written Good Faith Estimate before the procedure, and ask the pathology lab for its own. Labs often bill separately and may not be included in the surgeon's estimate. If the closure might need a flap or graft, ask for that to be estimated too, even if the surgeon can't be sure until the day. Ask whether the office has a self-pay rate, and whether a payment plan is offered directly rather than through a third-party lender. These questions often reduce the bill more than any change of country would.
Melanoma is a pathway, not a procedure
Melanoma and higher-risk cancers can involve staging, imaging, lymph node assessment and a surveillance schedule that runs for years. That's oncology, not a skin procedure, and it should be priced as a care plan with the team that will follow you. Our cancer treatment cost comparison explains why continuity of care dominates cancer costs.
Why skin cancer is a weak case for medical travel
A procedure that's short and sometimes expensive in the U.S. might seem a good candidate for treatment abroad. In practice, most of the cost and almost all the risk sit in steps that have to happen near home.
- Diagnosis comes first. A biopsy and pathology report confirm the type of cancer before anyone plans treatment. That is usually done locally.
- The procedure is short, but the wound needs checks. You may need to return for stitch removal and a wound check. MSK's instructions tell patients not to travel after surgery (MSK, 2023). If the procedure is on your face, CDC's guidance on flying after facial procedures, based on the American Society of Plastic Surgeons' advice to wait 7 to 10 days, is worth discussing with the surgeon (CDC Yellow Book, 2026).
- Surveillance lasts for life. Anyone who's had skin cancer needs regular skin checks, and they have to happen where you live.
- Insurance usually covers it. For insured patients, the U.S. figure is their cost-sharing, which may be less than flights alone.
Treatment abroad mainly makes sense for people who already live or spend long periods there, or who are uninsured and can plan the whole sequence, including the wound check, within one stay.
If you're being treated abroad anyway
Expats and long-stay visitors in Colombia and elsewhere can be treated locally like any other resident. Ask:
- Is the surgeon a dermatologist trained in Mohs, and who examines the tissue? In Mohs, it's usually the surgeon.
- Is the pathology lab on site or outside, and is its fee included?
- What closure do you expect, and who does it?
- How many follow-up visits are included, and when are stitches removed?
- Can I have the pathology report and operative note in English for my doctor at home?
In Colombia, you can check a doctor's specialty in the ReTHUS health-worker registry. Keep copies in English, as CDC suggests for anyone treated overseas (CDC Yellow Book, 2026). The document that matters most here is the pathology report showing whether the margins were clear; your dermatologist at home will plan surveillance from it.
Building a quote that you can compare
Whatever the country, ask for these lines separately: consultation, biopsy and pathology if not already done, the removal procedure with the number of layers assumed, the closure, any second surgeon, the facility if not an office, the wound check and stitch removal, and the first surveillance visit. A quote that names only "Mohs surgery" leaves out most of the decisions that set the price. For a sense of what specialist visits cost in different countries, see our consultation fee guide.

Frequently asked questions
Why is Mohs surgery hard to price in advance?
The surgeon removes and checks layers until the edges are clear, so the number of layers isn't known until the day. Ask how your quote handles additional layers and the wound closure.
Is Mohs surgery done under general anesthesia?
Usually not. Memorial Sloan Kettering's patient guide says Mohs uses a local anesthetic only, and that the visit can last several hours or the whole day depending on how many layers are needed.
Why can reconstruction cost more than removing the cancer?
Larger wounds, especially on the face, may need a flap or graft, or a plastic surgeon. That's a separate repair with its own fee, and possibly a facility and anesthesia charge.
Is it worth traveling abroad for skin cancer surgery?
Rarely. Diagnosis, wound checks and lifelong skin surveillance happen near home, and insured patients usually pay only their cost-sharing. Treatment abroad mainly suits people who live or stay there for long periods.
What records should I keep after treatment?
The pathology report with margin status and the operative note, in English if treated abroad. CDC advises sharing overseas records with your clinicians at home, and your dermatologist will need them for surveillance.
