Pressure ulcer surgery

About 15958: Trochanteric ulcer excision with ostectomy and muscle flap

Reports excision of a trochanteric pressure ulcer with underlying bone removal and muscle or myocutaneous flap coverage.

This operation treats a pressure ulcer over the greater trochanter by removing the ulcer and performing an ostectomy, then covering the defect with a muscle or myocutaneous flap. Plastic and reconstructive surgeons commonly perform it for deep, complex wounds, including in patients with prolonged immobility or spinal cord injury. It is a facility-based reconstructive procedure rather than simple wound closure or surface debridement.

Choose this code when the operative report supports all three elements: trochanteric ulcer excision, bone removal, and muscle or myocutaneous flap coverage. Document the ulcer site, the ostectomy, and the flap used. The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is barred; co-surgeons require supporting documentation, and team surgery is not permitted.

15958 billing questions

When is 15958 selected instead of 15956?

Use 15958 when the trochanteric ulcer excision includes both an ostectomy and muscle or myocutaneous flap coverage. Code 15956 describes the muscle or myocutaneous flap approach without the ostectomy element.

How does 15958 differ from 15953?

Both include trochanteric ulcer excision and ostectomy, but 15958 uses muscle or myocutaneous flap coverage; 15953 uses a skin flap.

What operative documentation supports 15958?

Document the ulcer's trochanteric location, excision, bone removal, and the muscle or myocutaneous flap used for coverage. The record should make clear that these elements were performed in the same operation.

Can modifier 50 be reported for bilateral trochanteric ulcers?

No. CMS identifies bilateral adjustment as inapplicable to this code, so modifier 50 is inappropriate.

How are additional same-session procedures and postoperative care handled?

The 90-day global includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction.

Can an assistant or co-surgeon be reported?

Assistant-at-surgery payment is barred for this code. Co-surgeons are paid only when supporting documentation is provided; team surgery is not permitted.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
