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 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 any affected muscle. In some cases, the procedure may also involve the excision of the bursa and any involved bone or bony protuberances, ensuring that surrounding nerves and blood vessels are protected throughout the process. After the excision, any rough bony surfaces are smoothed to prepare the wound bed adequately for the placement of the muscle or myocutaneous flap or skin graft. Common types of flaps that may be utilized include the tensor fascia lata flap, vastus lateralis myocutaneous flap, gluteal thigh flap, and anterior thigh flap. It is important to note that this procedure is coded as CPT® 15958 when ostectomy is performed, while CPT® 15956 is used when the procedure is conducted without the removal of bone.

The procedure is indicated for patients presenting with a trochanteric pressure ulcer, which may be associated with the following conditions:
The procedure involves several critical steps to ensure the effective excision of the trochanteric pressure ulcer and preparation for closure:
Post-procedure care involves monitoring the surgical site for signs of infection, ensuring proper wound care, and facilitating healing. Patients may require follow-up visits to assess the healing process and the success of the flap or graft placement. Pain management and rehabilitation may also be necessary to support recovery and restore function in the affected area.

| 51 | Multiple procedures: when multiple procedures, other than e/m services, physical medicine and rehabilitation services or provision of supplies (eg, vaccines), are performed at the same session by the same individual, the primary procedure or service may be reported as listed. the additional procedure(s) or service(s) may be identified by appending modifier 51 to the additional procedure or service code(s). note: this modifier should not be appended to designated "add-on" codes (see appendix d). | 58 | Staged or related procedure or service by the same physician or other qualified health care professional during the postoperative period: it may be necessary to indicate that the performance of a procedure or service during the postoperative period was: (a) planned or anticipated (staged); (b) more extensive than the original procedure; or (c) for therapy following a surgical procedure. this circumstance may be reported by adding modifier 58 to the staged or related procedure. note: for treatment of a problem that requires a return to the operating/procedure room (eg, unanticipated clinical condition), see modifier 78. | 59 | Distinct procedural service: under certain circumstances, it may be necessary to indicate that a procedure or service was distinct or independent from other non-e/m services performed on the same day. modifier 59 is used to identify procedures/services, other than e/m services, that are not normally reported together, but are appropriate under the circumstances. documentation must support a different session, different procedure or surgery, different site or organ system, separate incision/excision, separate lesion, or separate injury (or area of injury in extensive injuries) not ordinarily encountered or performed on the same day by the same individual. however, when another already established modifier is appropriate it should be used rather than modifier 59. only if no more descriptive modifier is available, and the use of modifier 59 best explains the circumstances, should modifier 59 be used. note: modifier 59 should not be appended to an e/m service. to report a separate and distinct e/m service with a non-e/m service performed on the same date, see modifier 25. | 62 | Two surgeons: when 2 surgeons work together as primary surgeons performing distinct part(s) of a procedure, each surgeon should report his/her distinct operative work by adding modifier 62 to the procedure code and any associated add-on code(s) for that procedure as long as both surgeons continue to work together as primary surgeons. each surgeon should report the co-surgery once using the same procedure code. if additional procedure(s) (including add-on procedure(s) are performed during the same surgical session, separate code(s) may also be reported with modifier 62 added. note: if a co-surgeon acts as an assistant in the performance of additional procedure(s), other than those reported with the modifier 62, during the same surgical session, those services may be reported using separate procedure code(s) with modifier 80 or modifier 82 added, as appropriate. | 78 | Unplanned return to the operating/procedure room by the same physician or other qualified health care professional following initial procedure for a related procedure during the postoperative period: it may be necessary to indicate that another procedure was performed during the postoperative period of the initial procedure (unplanned procedure following initial procedure). when this procedure is related to the first, and requires the use of an operating/procedure room, it may be reported by adding modifier 78 to the related procedure. (for repeat procedures, see modifier 76.) | 79 | Unrelated procedure or service by the same physician or other qualified health care professional during the postoperative period: the individual may need to indicate that the performance of a procedure or service during the postoperative period was unrelated to the original procedure. this circumstance may be reported by using modifier 79. (for repeat procedures on the same day, see modifier 76.) | AS | Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery | GC | This service has been performed in part by a resident under the direction of a teaching physician | LT | Left side (used to identify procedures performed on the left side of the body) | RT | Right side (used to identify procedures performed on the right side of the body) | XS | Separate structure, a service that is distinct because it was performed on a separate organ/structure | XU | Unusual non-overlapping service, the use of a service that is distinct because it does not overlap usual components of the main service |
