Summary & Overview
CPT 15953: Trochanteric Pressure Ulcer Excision with Skin Flap Closure
CPT code 15953 describes surgical excision of a pressure ulcer involving the trochanteric bone of the hip with closure using a skin flap. This code captures a complex operative procedure that combines removal of infected or necrotic soft tissue and underlying bone with reconstructive flap coverage to restore durable soft-tissue integrity. Nationally, procedures coded with 15953 are clinically significant due to their association with advanced pressure injuries, extended perioperative care, and higher resource use.
Key payers in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for when 15953 is reported, typical sites of service, and the types of surgical care represented by the code. The publication summarizes common modifiers and payer considerations where available, highlights benchmarks and utilization patterns when present, and notes relevant policy updates affecting operative management and coverage of pressure ulcer debridement with flap reconstruction. Practical coding context included here assists billing professionals, surgical teams, and policy analysts in understanding the clinical and administrative importance of reporting CPT code 15953 for trochanteric pressure ulcer excision with flap closure.

Billing Code Overview
CPT code 15953 describes surgical removal of a pressure ulcer and the underlying trochanteric bone of the hip with wound closure using a skin flap. The procedure involves excision of necrotic and infected tissue down to and including the underlying bone of the trochanter, followed by reconstruction of the defect with a local or regional skin flap to achieve durable soft-tissue coverage.
-
Service type: Surgical debridement and soft-tissue reconstruction (flap closure)
-
Typical site of service: Hospital operating room or ambulatory surgical center for operative management of complex pressure ulcers involving bone
Clinical & Coding Specifications
Clinical Context
A typical patient is an older adult with limited mobility who presents with a chronic, deep trochanteric pressure ulcer that has exposed necrotic bone and failed conservative wound care. The patient often has comorbidities such as diabetes mellitus, peripheral vascular disease, or chronic steroid use, and may reside in a long-term care facility or require skilled nursing. Preoperative workflow includes wound assessment, sharp debridement attempts, imaging (plain radiographs or CT) to evaluate bony involvement, and infectious disease evaluation if osteomyelitis is suspected. The surgical plan is for excision of the pressure ulcer and resection of the underlying trochanteric bone followed by immediate soft tissue reconstruction using a local or regional flap (eg, gluteal fasciocutaneous or musculocutaneous flap) to achieve durable coverage. Intraoperative steps include positioning, wide excision to healthy tissue, bone resection as indicated, flap design and elevation, dead-space management, layered closure, and placement of drains. Postoperative workflow includes flap monitoring, wound care, antibiotics if indicated, offloading strategies, physical therapy for mobility and pressure redistribution, and coordination with case management for discharge planning to home or facility with continued wound support.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when the procedure required substantially greater work than typical (extensive debridement, prolonged soft-tissue reconstruction). |
23 | Unusual anesthesia | Use when general or regional anesthesia is contraindicated and the procedure is performed under local anesthesia with significant patient distress. |
26 | Professional component | Use when reporting only the surgeon's professional service separate from technical component (rare for this fully surgical CPT). |
50 | Bilateral procedure | Use if identical procedures are performed on both trochanters in the same operative session. |
51 | Multiple procedures | Use when this flap procedure is billed with additional distinct surgical procedures during the same session. |
52 | Reduced services | Use when the procedure is partially reduced or discontinued (eg, attempted flap but aborted). |
53 | Discontinued procedure | Use when the procedure is terminated due to extenuating circumstances prior to completion. |
62 | Two surgeons | Use when two surgeons with different skills perform portions of the procedure (eg, orthopedic and plastic surgeons). |
63 | Procedure performed on infants less than 4 kg | Rarely applicable; use only if patient meets weight criteria. |
78 | Return to operating room for a related procedure during global period | Use when a complication requires reoperation related to the original procedure during the global period. |
| Taxonomy Code | Specialty | Notes |
|---|---|---|
| 207P00000X | Orthopedic Surgery | Orthopedic surgeons may perform trochanteric bone resection when bony involvement or osteomyelitis is present. |
| 208000000X | General Surgery | General surgeons experienced in complex wound and flap reconstruction perform this procedure in many centers. |
| 208100000X | Plastic Surgery | Plastic and reconstructive surgeons frequently perform flap closure and soft-tissue reconstruction for trochanteric pressure ulcers. |
| 363L00000X | Wound Care Specialist | Physicians with wound care focus coordinate pre- and postoperative management, though they do not typically perform flap surgery. |
