Summary & Overview

CPT 15944: Hip Pressure Sore Excision with Skin Flap Closure

CPT code 15944 denotes surgical excision of a pressure sore in the hip region with closure using a skin flap. This procedure is a reconstructive soft-tissue operation intended to provide durable wound coverage, prevent recurrence, and restore local tissue integrity. Nationally, accurate coding for pressure-ulcer flap reconstruction affects surgical quality reporting, utilization monitoring, and payment across major commercial and public payers.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for use of this code, typical sites of service, and the kinds of measures and benchmarks that tend to accompany reconstructive pressure-ulcer surgery. The publication summarizes common modifier usage (data provided), payer coverage patterns (when available), and related clinical considerations such as the surgical objective of flap coverage and the need for comprehensive wound management.

This summary prepares clinicians, billing staff, and policy analysts to interpret procedural documentation and align billing with clinical intent. Data not available in the input is noted where applicable, and readers will learn what information is typically required to support claims and quality review for pressure-ulcer flap reconstruction.

Billing Code Overview

CPT code 15944 describes removal of a pressure sore (decubitus ulcer) located in the hip area with closure of the defect using a skin flap to achieve durable wound coverage and reduce recurrence. The procedure involves debridement of the ulcer bed and reconstruction with local or regional flap techniques tailored to the hip pressure-area defect.

Service Type: Surgical wound debridement and flap reconstruction of a pressure ulcer.

Typical Site of Service: Hospital operating room or outpatient surgical center, depending on patient condition and surgical complexity.

Clinical & Coding Specifications

Clinical Context

A typical patient is an older adult with limited mobility who presents with a chronic, full-thickness pressure ulcer over the hip (greater trochanter) that has failed conservative wound care, including offloading, debridement, and advanced dressings. The wound demonstrates stable bacterial control, adequate nutritional status, and absence of uncontrolled systemic infection, and is assessed as appropriate for definitive surgical closure with a soft-tissue flap. The clinical workflow includes preoperative evaluation (medical history, vascular assessment, optimization of comorbidities such as diabetes and anemia), imaging as needed, perioperative antibiotics, operative flap harvest and transfer to cover the defect, layered closure, application of drains if indicated, and postoperative protocols for offloading, dressing changes, and physical therapy. Typical perioperative documentation includes wound size, location (hip/trochanteric), prior debridement history, flap type, estimated blood loss, intraoperative findings, drain placement, and explicit description of closure technique to support code 15944.

Coding Specifications

Modifier	Description	When to Use
`22`	Increased procedural services	Use when work or complexity substantially exceeds usual for a flap closure due to extensive dissection, fibrosis, or prolonged operative time documented in the record.

Taxonomy Code	Specialty	Notes
Data not available in the input.	Plastic Surgery	Plastic surgeons commonly perform myocutaneous or fasciocutaneous flap reconstructions for pressure ulcers.
Data not available in the input.	General Surgery	General surgeons at specialty centers perform complex wound reconstructions when plastic surgery is unavailable.
Data not available in the input.	Orthopedic Surgery	Orthopedic surgeons occasionally perform soft-tissue coverage procedures over bony prominences in collaboration with plastic surgery.
Data not available in the input.	Wound Care/Hyperbaric Specialists	Wound care specialists coordinate pre- and postoperative care, though they are not usually the primary flap surgeon.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`L89.152`	Pressure ulcer of left hip, stage 4	Stage 4 trochanteric pressure ulcers with full-thickness tissue loss commonly require flap reconstruction like `15944`.
`L89.153`	Pressure ulcer of left hip, unstageable	Unstageable ulcers once debrided and confirmed as full thickness may proceed to flap closure.
`L89.052`	Pressure ulcer of right hip, stage 4	Contralateral trochanteric ulcers requiring similar reconstructive approach.
`L89.053`	Pressure ulcer of right hip, unstageable	As above for unstageable ulcers after appropriate evaluation.
`E11.9`	Type 2 diabetes mellitus without complications	Diabetes is a common comorbidity that affects wound healing and is frequently present in patients undergoing flap reconstruction for pressure ulcers.
`M48.06`	Spinal stenosis, lumbar region	Neurologic deficits and immobility from spinal disease can predispose to pressure ulcer formation at the hip.
`Z48.298`	Encounter for other postoperative aftercare following other orthopedic or soft tissue procedure	Used for postoperative management visits after flap reconstruction when applicable.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`11042`	Debridement, muscle and/or fascia (first 20 sq cm or less)	Commonly performed prior to flap closure to remove necrotic tissue and prepare a clean wound bed; may be billed separately if documentation supports debridement beyond that integral to the closure.
`13160`	Secondary closure of surgical wound, complicated	Used for closure of complicated wounds; may be performed if less complex closure than flap reconstruction is chosen or for layered closure of donor/recipient sites.
`15734`	Muscle, myocutaneous or fasciocutaneous flap with microvascular anastomosis	Used when a free flap with microvascular anastomosis is performed; relates to `15944` when pedicled flap is insufficient and a free flap is required.
`97605`	Negative pressure wound therapy (management of surgical wound)	Often used postoperatively for wound management prior to definitive closure or for adjunctive therapy after flap closure in complex cases.
`96365`	Intravenous infusion, therapeutic, prophylactic, or diagnostic	Used for perioperative IV antibiotics or fluids when documented as separate infusion services during the same encounter.
