Prepare now for a big change in how you code your dermatologist's Moh's micrographic surgery.
CPT 2007 deletes existing Moh's codes 17304-17310 and replaces them with five new codes (17311-17315). The new codes break the procedure down into two categories: for head, neck, hands, feet and genitalia,;or for trunk, arms and legs. Where the old codes talked about -specimens,- the new codes talk about -blocks.-
The old Moh's surgery codes divided the add-on codes into second stage, third stage and each additional stage. But the new codes simply include one add-on code for each additional stage after the first. For Moh's surgery of the trunk, arms or legs, you also have an add-on code for each additional block after the first five blocks.
