CPT 15934: Excision of Sacral Pressure Sore with Flap Closure

CPT code 15934 covers surgical excision of a pressure ulcer at the base of the spine with flap closure to achieve definitive wound coverage and lower risk of recurrence. This procedure is clinically significant for patients with chronic sacral or coccygeal pressure sores that have failed conservative care, and it carries implications for surgical capacity, inpatient utilization, and post-operative wound-management resources nationwide.

Key payers considered in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service and expected sites of care, along with national benchmarking context, common billing modifiers and coding considerations, and pointers to relevant policy updates affecting coverage and payment. The publication summarizes expected utilization patterns, relative complexity compared with simpler debridement codes, and documentation elements that typically support medical necessity. Where specific payer policies differ or are unavailable, the report identifies areas where plan-level review is commonly required.

This executive summary is intended for health system revenue leaders, surgical and wound-care clinicians, and coding and compliance professionals seeking a national overview of CPT code 15934 and its operational and policy implications.

Billing Code Overview

CPT code 15934 describes the surgical removal of a pressure sore located at the base of the spine with subsequent closure using a skin flap to promote complete healing and reduce recurrence. This procedure involves excision of the chronic ulcer and reconstruction of the defect with a local or regional soft-tissue flap.

Service type: Surgical debridement and soft-tissue reconstruction (flap closure)
Typical site of service: Inpatient or outpatient surgical setting, commonly performed in an operating room due to the need for flap reconstruction and anesthesia

Data not available in the input.

Clinical Context

A typical patient is an adult with a chronic, deep sacral pressure ulcer (decubitus ulcer) that has failed conservative wound care, presenting for surgical debridement and closure. The patient commonly has comorbidities such as spinal cord injury with paraplegia, diabetes mellitus, or limited mobility. Preoperative evaluation includes wound assessment, imaging if osteomyelitis is suspected, laboratory studies (CBC, CMP, coagulation), and optimization of nutrition and glycemic control. The procedure is performed in an operating room under general or regional anesthesia. The surgeon excises the ulcer and devitalized tissue down to healthy tissue, then reconstructs the defect using a local or regional myocutaneous or fasciocutaneous flap (for example, gluteal or posterior thigh flap) with layered closure, drains as needed, and sterile dressing. Postoperative workflow includes inpatient wound monitoring, pressure offloading, antibiotics as indicated, pain control, flap viability checks, and coordination with physical therapy and home care for pressure redistribution and wound surveillance. Typical site of service is an ambulatory surgery center or hospital outpatient / inpatient operating room depending on complexity and patient comorbidities. Service type: surgical, soft tissue reconstruction for pressure ulcer using flap closure.
