Summary & Overview
CPT 15937: Sacral Pressure Sore Excision with Skin/Muscle Graft
CPT code 15937 represents excision of a sacral pressure sore with removal of underlying bone and preparation of the wound for closure using a skin graft or combined skin-and-muscle graft. This is a significant reconstructive procedure used for complex, full-thickness decubitus ulcers that involve bone exposure or osteomyelitic risk, making it relevant to hospitals, surgical centers, and wound care programs nationwide.
Key national payers relevant to coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers can expect an overview of clinical indications and procedural context, typical sites of service, and common billing considerations tied to this operative approach. The publication will also summarize available benchmarks and payer coverage themes, outline relevant clinical context for surgical reconstruction of pressure injuries, and note policy updates affecting authorization and coding practices when applicable.
Intended for clinicians, billing professionals, and policy analysts, the report explains the clinical role of CPT code 15937, how it fits within surgical wound management pathways, and what stakeholders typically evaluate for medical necessity and appropriate site of service.
Billing Code Overview
CPT code 15937 describes a surgical procedure to remove a pressure sore (decubitus ulcer) in the sacral area along with the underlying bone, and to prepare the wound for closure using a skin graft or a combined skin and muscle graft. This procedure is a form of reconstructive soft-tissue surgery addressing complex, full-thickness pressure injuries.
-
Service type: Surgical debridement and reconstructive grafting for pressure sore excision
-
Typical site of service: Inpatient hospital or ambulatory surgical center, commonly performed in an operating room due to the extent of tissue removal and grafting required
Clinical & Coding Specifications
Clinical Context
A typical patient is a 68-year-old wheelchair-bound individual with a chronic, nonhealing stage IV sacral pressure ulcer exposing bone and recurrent osteomyelitis despite conservative care. The patient is evaluated by a multidisciplinary team including wound care, infectious disease, and plastic surgery. After preoperative optimization (nutritional support, glycemic control, and targeted antibiotics), the patient is taken to the operating room for surgical debridement. The surgeon performs excision of the pressure ulcer and partial sacrectomy of necrotic bone, followed by preparation of the wound bed and reconstruction using a myocutaneous or fasciocutaneous flap with skin grafting as indicated. Intraoperative documentation includes indication, ulcer stage and dimensions, extent of bone resection, method of wound bed preparation, type and source of flap or graft, estimated blood loss, complications, and specimens sent for culture and pathology. Typical postoperative workflow involves wound monitoring, flap viability assessment, continued targeted antibiotics if osteomyelitis was present, pressure offloading, and planned outpatient or inpatient wound care follow-up.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work or complexity substantially exceeds typical for 15937 and documentation supports reason for additional work. |
23 | Unusual anesthesia | Use when general anesthesia is medically contraindicated and unusual anesthesia circumstances are required for 15937. |
26 | Professional component | Use if reporting only the surgeon's professional component separate from technical services (rare for 15937). |
50 | Bilateral procedure | Use if symmetrical bilateral sacral procedures are performed (generally uncommon for 15937). |
51 | Multiple procedures | Use when 15937 is performed in the same session with other distinct procedures; report modifier on secondary procedures per payer rules. |
52 | Reduced services | Use when the procedure is partially reduced or not completed; document reason. |
53 | Discontinued procedure | Use when 15937 is started but stopped due to extenuating circumstances; document why. |
58 | Staged or related procedure or service by the same physician during the postoperative period | Use when 15937 is the planned first stage of a staged reconstruction. |
59 | Distinct procedural service | Use to indicate a distinct procedural service when 15937 is performed with other procedures not typically bundled, with supporting documentation. |
62 | Two surgeons | Use when two surgeons operate together, each reporting their portion of 15937 as appropriate. |
73 | Discontinued outpatient procedure prior to anesthesia due to patient-related issues | Use when 15937 is cancelled after patient taken to OR but before anesthesia administered. |
76 | Repeat procedure by same physician | Use when 15937 is repeated by the same surgeon during the global period for a separate, documented reason. |
78 | Return to the operating room for a related procedure during the postoperative period | Use when reoperation related to the initial 15937 occurs during the global period. |
80 | Assistant surgeon | Use when an assistant surgeon is required for 15937 and payer allows assistant surgeon reimbursement. |
