Neurosurgery Coding Alert

Question: What CPT^® code can we use for debridement of craniotomy wound infection done under general anesthesia. The craniotomy was done two years ago.

Answer: You need to determine the extent of the debridement. You can choose from 11042 (Debridement, subcutaneous tissue [includes epidermis and dermis, if performed]; first 20 sq cm or less) – +11047 (Debridement, bone [includes epidermis, dermis, subcutaneous tissue, muscle and/or fascia, if performed]; each additional 20 sq cm, or part thereof [List separately in addition to code for primary procedure]) depending upon the area that was debrided.

If however, your surgeon removes the flap entirely, you would report craniotomy codes.
