Mohs micrographic surgery: Definition
A staged skin cancer excision in which the same physician acts as surgeon and pathologist, billed by stage and by additional tissue block.
This is a short definition only. The full explanation lives on Mohs surgery billing and coding, which is the page to read if you are dealing with this on live claims.
Definition
Mohs is reported with a first-stage code for the anatomic area (17311 or 17313) and an additional-stage code for each subsequent stage (17312 or 17314), plus 17315 for each block beyond the first five within a single stage.
The defining requirement is that one physician performs both the excision and the microscopic examination during the same session.
