Prior Authorization

Code is covered without prior authorization (high confidence)
Documentation Required
- No explicit "Documentation Requirements" section is provided in this Clinical Policy Bulletin.
- Billing limitation/note that may affect documentation: "Mohs micrographic surgery requires a single physician to act in 2 integrated, but separate and distinct capacities: surgeon and pathologist. If either of these responsibilities is delegated to another physician who reports his/her services separately, the use of the Mohs micrographic surgery CPT codes is inappropriate."
