CPT® Code 15956

A trochanteric pressure ulcer, commonly known as a pressure sore, bedsore, or decubitus ulcer, is a localized injury to the skin and underlying tissue that typically occurs over bony prominences, such as the greater trochanter of the femur. This procedure involves the excision of the ulcer in preparation for subsequent closure using a muscle or myocutaneous flap or a skin graft. The greater trochanter is a prominent bony structure located on the outer aspect of the femur, serving as an attachment point for various muscles of the thigh and buttock. During the excision, the physician makes an incision around the ulcer, carefully removing all necrotic tissue, which includes the skin, subcutaneous tissue, and potentially muscle. In some cases, the bursa and any affected bone may also be excised to ensure complete removal of the ulcer and to prepare the wound bed adequately. The procedure emphasizes the importance of protecting surrounding nerves and blood vessels during the excision process. After the necrotic tissue is removed, any rough bony surfaces are smoothed to facilitate proper healing. The wound edges are then trimmed, and the site is prepared for the placement of a muscle or myocutaneous flap or skin graft, which will be performed as a separate procedure. It is important to note that if the procedure is conducted without the removal of bone, the appropriate code to use is 15956, whereas if ostectomy is performed, the code 15958 should be utilized.
