Summary & Overview
CPT 44322: Colostomy/Cecostomy Stoma Creation with Biopsy
CPT code 44322 identifies a surgical stoma procedure in which a loop of colon or cecum is exteriorized, incised, sutured to the abdominal wall, and sampled with multiple biopsies. This procedure establishes direct access to the large intestine for decompression, diversion, or therapeutic management, and the concurrent biopsies inform diagnostic and pathological assessment. Nationally, this code is relevant across acute care surgery, colorectal specialty practices, and hospital reimbursement systems because it represents a definitive operative intervention with potential inpatient utilization and postoperative resource needs.
Key payers commonly involved in coverage and payment for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical description, service line and site-of-service context, and coverage and billing considerations tied to common modifiers and payer practices. The publication also outlines benchmarks and policy-relevant updates affecting coding, documentation, and claims processing for complex abdominal surgical procedures. The material is intended to support coding accuracy, revenue cycle alignment, and clinical documentation that reflects the operative steps and biopsy component of the service.
Billing Code Overview
CPT code 44322 describes a surgical procedure in which a segment of the large intestine (colon or cecum) is mobilized and brought to an incision in the abdominal wall to create a stoma. The surgeon incises the exteriorized intestinal segment and secures it to the abdominal wall to provide direct access to the bowel, commonly for decompression or fecal diversion. Multiple biopsy samples along the length of the exteriorized intestine are obtained as part of the procedure.

Service type: Surgical stoma creation with intraoperative intestinal biopsy

Clinical & Coding Specifications
Clinical Context
A 64-year-old patient with chronic refractory colonic inertia and recurrent fecal impaction is scheduled for creation of a temporary or permanent colostomy for bowel decompression and access. The patient has failed conservative therapies including laxatives and enemas, and continues to have obstructive symptoms with proximal colonic dilatation on imaging. Under general anesthesia in an operating room or ambulatory surgical center, the surgeon mobilizes a segment of the sigmoid colon (or cecum/right colon if indicated), brings a loop of bowel through a planned abdominal wall incision, opens the bowel lumen, and matures the bowel edges to the skin to create a stoma. During the same operative session, the surgeon obtains multiple mucosal biopsy specimens along the pulled-through segment to evaluate for inflammatory, ischemic, or neuropathic pathology. Intraoperative steps include bowel selection and mobilization, spawning a stoma tract, mucosal incision, biopsy sampling, and maturation of the bowel to the abdominal wall. Typical perioperative workflow includes pre-op consent and bowel prep as indicated, general anesthesia, surgical procedure in the OR or ASC, immediate stoma care teaching, and post-anesthesia recovery with short inpatient stay or same-day discharge depending on comorbidity and complexity.
