The best thing for you to do is to talk to your Mohs surgeon and the dermatology office about what is covered and what is not. The actual removal of the tissue and repair is usually covered at our office as part of the entire Mohs procedure, but I am not sure what happens to patients if they go to a plastic surgeon after their Mohs for any revision or further procedures. There is a chance those types of things would not be covered. The insurance world is very complicated, so best to check with your derm office so you will know what you will be responsible for as far as payment, but good idea to get the skin cancer on the scalp treated as SCC can be dangerous and disfiguring if not fully removed.
