CPT Code Overview
CPT 11043 describes debridement of muscle and/or fascia, which includes removal of the epidermis, dermis, and subcutaneous tissue if performed. This procedure is a surgical intervention within the integumentary system, typically used to treat complex wounds or infections that require removal of damaged or infected tissue to promote healing. The service is commonly performed in an inpatient hospital (POS 21), outpatient hospital (POS 22), or ambulatory surgical center (POS 24).
Clinical & Coding Specifications
Clinical Context
A typical patient scenario involves an individual with a chronic lower extremity wound, such as a diabetic ulcer or an ulcer due to peripheral arterial disease. The patient may present to an inpatient hospital, outpatient hospital, or ambulatory surgical center for surgical debridement. The procedure coded as 11043 is performed to remove necrotic muscle and/or fascia, which may include removal of epidermis, dermis, and subcutaneous tissue if necessary. The clinical workflow includes assessment of the wound, determination of the extent of tissue involvement, and surgical removal of nonviable tissue to promote healing and prevent infection. This service is commonly performed by providers specializing in surgical critical care, general surgery, or emergency medicine.
