Coding —Surgery: Integumentary System
Question: The patient has a large 4-cm sebaceous cyst in the middle of the back. The incision was made right over the cyst, cutting through skin and subcutaneous tissue. Should this be reported from the Integumentary or Musculoskeletal system codes?
Answer: The appropriate code for this procedure (excision of benign lesion codes 11400-11406 of the Integumentary subsection) is based on the size of the excised diameter. These tumors originate from the dermis or adnexal structures and are not considered soft tissue tumors, even though they may protrude into subcutaneous tissue.
