I have an op note stating a 6 cm lipoma was excisied from the upper back area. Excision was carried down through the subcutaneous tissure. The deep subcutaneous tissue was closed with interrupting vicryl suture and the skin was closed with 4-0 monocryl stitches. Would I code this using 21933 or 11426 & 12032? I always seem to question whether to use the integumentary or musculoskeletal section.
