CPT code 44140 represents a partial colectomy with primary anastomosis — the surgical removal of a segment of the colon followed by reconnection of the remaining ends. This procedure is a common operative approach for conditions such as colonic neoplasia, diverticular disease, ischemia, and other causes of localized colonic pathology, and it has significant implications for hospital surgical throughput, payment policy, and post-operative quality measurement. Nationally, this code matters because it captures a high-acuity inpatient surgical service with substantial resource use and variability in clinical pathways.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes how payers classify and reimburse this operative service, typical sites of service, and clinical contexts linked to the code.
