It depends on the number of excisions required plus the closure

Moh's would be considered a medically necessary procedure and as such should be covered by health insurance. So would the wound reconstruction after excision of the BCC. The number of excisions it takes to clear the tumor usually determines the cost of the Moh's treatment in addition to the complexity of the closure.

There is no way to give you cost estimates in your situation. All I can recommend is that you find an excellent Moh's performing dermatologist in your area and ask.
