Summary & Overview

CPT 45395: Laparoscopic Total Proctectomy with End Colostomy

CPT code 45395 denotes a laparoscopic total proctectomy with creation of an end colostomy — a major colorectal surgical procedure used when removal of the entire rectum is required and a permanent stoma is created. This code captures a complex, operative intervention with significant implications for perioperative care, hospital resource use, and postoperative quality-of-life outcomes. Nationally, accurate coding for this procedure matters for inpatient surgical reimbursement, quality measurement, and tracking trends in minimally invasive colorectal surgery.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication summarizes how CPT code 45395 is used across inpatient surgical settings, highlights typical clinical and billing considerations, and outlines common modifiers that may accompany reporting (Data not available in the input for payer-specific fee schedules).

Readers will find: concise clinical context for the procedure; expected site of service and service line framing; an explanation of why precise coding matters for case mix, post-acute planning, and quality reporting; and guidance on what information is available versus missing from the input. The piece is intended to support coding professionals, surgical program managers, and payers in understanding how CPT code 45395 fits into national surgical practice and billing workflows.

Billing Code Overview

CPT code 45395 describes a laparoscopic total proctectomy with end colostomy (abdominoperineal resection with permanent colostomy). The procedure involves removal of the entire rectum using laparoscopic techniques, followed by exteriorization of the remaining colon and creation of a permanent stoma on the abdominal wall.

Service type: Surgical — laparoscopic colorectal resection with permanent ostomy

Typical site of service: Inpatient hospital operating room

Clinical & Coding Specifications

Clinical Context

A typical patient is a 62-year-old with locally advanced rectal adenocarcinoma who presents after neoadjuvant chemoradiation with persistent tumor involving the rectum and perirectal tissues. After multidisciplinary review, the surgical team schedules a planned laparoscopic abdominoperineal resection with end colostomy creation. The patient undergoes preoperative bowel preparation, anesthesia evaluation, and perioperative antibiotics. In the operating room, the colorectal surgeon performs a laparoscopic total proctectomy, mobilizes the sigmoid colon, divides the rectum and anus, and matures a permanent end colostomy on the abdominal wall. Postoperative workflow includes recovery in post-anesthesia care, pain management, early ambulation, ostomy teaching by Wound, Ostomy, and Continence (WOC) nurses, and inpatient monitoring for return of bowel function and wound healing. Typical sites of service are the inpatient hospital operating room and post-anesthesia/postoperative units. The service type is a major surgical procedure (laparoscopic proctectomy with colostomy) typically billed as surgical inpatient care.
