Summary & Overview
CPT 15920: Sacrococcygeal Pressure Sore Debridement with Bone Excision
CPT code 15920 describes surgical debridement of a sacrococcygeal pressure sore with excision of infected underlying bone and primary wound closure. This procedure addresses advanced pressure ulcers with osteomyelitic involvement at or near the tailbone, requiring operative removal of necrotic soft tissue and bone followed by suturing to achieve wound closure. Nationally, this code represents an important sick-care intervention for patients with severe decubitus ulcers, with implications for surgical utilization, hospital resource use, and postoperative wound care pathways.
Key payers considered include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a clinical and billing-focused overview that situates the procedure within surgical wound care, explains typical sites of service, and outlines related billing considerations. The publication presents benchmarks where available, notes relevant policy and coverage themes affecting reimbursement for complex wound procedures, and summarizes clinical context such as indications for bone excision and primary closure.
Intended audiences include hospital billing managers, surgical teams, coding professionals, and policy analysts who need a concise reference on coding and clinical context for operative management of sacrococcygeal pressure sores. Data not available in the input will be identified as such in detailed sections.
Billing Code Overview
CPT code 15920 describes a surgical procedure in which the provider removes a pressure sore (decubitus ulcer) over the tailbone area (sacrococcygeal region) and excises a portion of underlying infected bone, then closes the wound with sutures.
-
Service type: Surgical debridement with excision of infected bone and primary wound closure
-
Typical site of service: Operating room or procedural suite in an acute care hospital or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A typical patient is an elderly, immobile individual with a chronic stage 4 sacral pressure ulcer complicated by underlying osteomyelitis of the coccyx. The patient presents with increased wound drainage, foul odor, local erythema, and intermittent fever. Prior conservative measures (pressure offloading, wound care, systemic antibiotics) have failed to resolve the deep infection. The surgical team (usually a general surgeon or plastic surgeon) performs sharp excision of the pressure sore, debridement of necrotic soft tissue, and sequestrectomy or partial removal of the infected coccygeal bone, followed by layered closure or primary closure of the wound when feasible. Typical workflow includes preoperative wound assessment and imaging (X-ray or MRI to evaluate bony involvement), informed consent emphasizing risks of persistent infection and need for wound care, perioperative antibiotics, intraoperative debridement with removal of infected bone, hemostasis and irrigation, and suturing of the surgical site. Postoperative plan includes wound monitoring, targeted antibiotic therapy guided by cultures, pressure redistribution strategies, and outpatient or skilled nursing follow-up for wound care and possible further reconstructive procedures.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
11 | Normal or routine procedural service | Use when the procedure is performed as scheduled without complications and represents the provider's usual service. |
22 | Increased procedural services | Use when work required is substantially greater than typically required (extensive debridement beyond usual scope). |
52 | Reduced services | Use when the procedure is partially reduced or not completed as described. |
53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances. |
54 | Surgical care only | Use when only the surgical portion is billed and pre/postoperative care is billed by another provider. |
55 | Postoperative management only | Use when only postoperative care is billed by the reporting surgeon. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct operative work. |
63 | Procedure performed on infants less than 4 kg | Use when applicable by patient weight criteria. |
78 | Unplanned return to the OR for related procedure during global period | Use when the patient returns to the OR for a complication related to the original procedure. |
80 | Assistant surgeon | Use when an assistant-at-surgery performs part of the operation. |
81 | Minimum assistant surgeon | Use when a minimal assistant role is documented. |
82 | Assistant surgeon (when qualified resident not available) | Use when an assistant is required but a resident isn't available. |
26 | Professional component | Rarely used for this procedure; use when reporting only the professional component of a diagnostic service associated with the procedure. |
51 | Multiple procedures | Use when multiple procedures are performed during the same operative session and bundling rules apply. |

| 208K00000X | Plastic Surgery | Performs complex soft-tissue excision and closure or reconstructive procedures after debridement. |
| 208000000X | Colorectal Surgery | May be involved when sacral/coccygeal involvement requires specialized expertise. |
| 207L00000X | Surgical Oncology | Occasionally involved when complex wound management overlaps with oncologic resections. |
| 363A00000X | Wound Care Specialist | Provides perioperative wound management, debridement expertise, and follow-up care. |
