See board certified dermatologist
I am uncertain why the plan was changed, and agree that that is an important part of this question and answer. THe best next course of action would be to consult with a board certified dermatologist to get a second opinion.
Consent for Mohs
Do you know why the doctor changed the plan? I think that's what needs to be understood here. I don't know why it would have been done that way, but you and your physician need to discuss it. Because Mohs is a more extensive and expensive procedure, we do have patients sign a consent for it. In my practice I don't have patients sign for traditional excisions and removals. But I discuss with them why we do things. And I think that's important. We still don't know where your site was... and Mohs can only be reserved for areas that need tissue to be spared. It's not for all areas of the body and insurance simply may not cover it if they deem a traditional excision should have been done. Bottom line, talk about this with your doctor.
"This answer has been solicited without seeing this patient and
cannot be held as true medical advice, but only opinion. Seek in-person
treatment with a trained medical professional for appropriate care."
Generally we reserve mohs surgery for facial skin cancers that are poorly defined.
And this may vary by practitioner, I would suggest discussing with a Board Certified Dermatologist with expertise in Mohs surgery.
