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.
