CPT code 44136 represents a complex surgical intestinal reconstruction in which a recipient’s diseased segment of small bowel is transected and continuity is restored using intestine from a living donor. This procedure is clinically significant because it addresses severe small-bowel pathology or short-bowel syndromes where conventional resection and anastomosis are insufficient, and it often appears in tertiary-care and transplant center workflows.

Key national payers included in the accompanying analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context, typical sites of service, and the common modifiers associated with billing for this procedure. The publication also summarizes benchmark payment insights, utilization patterns across major payers, and notable policy or coverage trends affecting access and authorization for complex intestinal reconstructive surgery.

This resource is intended for hospital billing departments, transplant program administrators, and policy analysts seeking a clear, national-level reference for coding and payer considerations related to CPT code 44136. Data not available in the input is noted where specific payer rates, taxonomies, or ICD-10 pairings are required for deeper operational detail.
