Summary & Overview
HCPCS C9796: Repair of Enterocutaneous Fistula with Plug
HCPCS Level II code C9796 designates the surgical repair of enterocutaneous fistulas of the small intestine or colon using a plug (for example, porcine small intestine submucosa). This code captures a targeted biologic-plug technique distinct from standard fistula repair approaches and is relevant to hospitals, ambulatory surgery centers, and surgical specialty practices. Nationally, proper coding of this procedure affects clinical documentation, procedural tracking, and appropriate payer adjudication for a specialized surgical repair technique.
Key payers referenced in the analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of what the code represents, payer coverage considerations, and context for clinical service lines that commonly perform the procedure. The publication also outlines expected sites of service and common billing modifiers associated with complex surgical cases (modifier list provided separately).
This summary provides practical benchmarks for coding practice, highlights policy and coverage nuances that commonly arise with biologic plug repairs, and situates the procedure within surgical service lines such as colorectal surgery and general surgery. Data not available in the input includes specific ICD-10 pairings, associated taxonomies, related codes, and payer-specific reimbursement rates.
Billing Code Overview
HCPCS Level II code C9796 describes the repair of an enterocutaneous fistula of the small intestine or colon (excluding anorectal fistula) using a plug, for example a porcine small intestine submucosa (SIS) plug. This procedure is a surgical intervention to close an abnormal tract between the intestinal lumen and the skin surface, using a biologic plug to facilitate closure and tissue integration.
Service Type: Surgical repair using biologic plug (enterocutaneous fistula)
Typical Site of Service: Operating room or outpatient surgical center, with associated inpatient care when clinically indicated.
Clinical & Coding Specifications
Clinical Context
A 56-year-old patient with a history of multiple abdominal surgeries and Crohn disease presents with a persistent enterocutaneous fistula originating from the distal small intestine. Conservative measures including bowel rest, total parenteral nutrition, wound care, and local fistula management have failed over several weeks. The general surgery team evaluates the patient, obtains cross-sectional imaging (CT abdomen/pelvis with oral/IV contrast) and fistulogram to define anatomy, and determines the fistula tract is amenable to plug repair. The patient is optimized preoperatively for nutrition and infection control, taken to the operating room under general anesthesia, and the fistula tract is surgically debrided and repaired with placement of a biologic plug (e.g., porcine small intestine submucosa). The intraoperative record documents the location (small intestine or colon), excision of epithelialized tract as needed, and secure placement of the plug with appropriate suturing. Postoperative workflow includes inpatient monitoring for return of bowel function, wound and drain management, and follow-up imaging or clinical assessment to confirm fistula closure. Typical site of service is an inpatient or outpatient surgical center specializing in general or colorectal surgery. Service type: operative surgical repair of enterocutaneous fistula using a biologic plug (HCPCS Level II C9796).
