Summary & Overview
CPT 44213: Laparoscopic Mobilization of Splenic Flexure (Add-on)
CPT code 44213 is an add-on laparoscopic procedure for mobilization of the splenic flexure performed during the same session as a partial colectomy. The code captures intraoperative work to prepare adequate colonic length for anastomosis or resection and is relevant for hospitals, ambulatory surgical centers, and surgical specialists who bill for colorectal and general surgery services. Nationally, accurate reporting of this add-on code affects surgical episode accounting, resource allocation, and appropriate payment for additional intraoperative complexity.
Key payers covered in this review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical intent and service setting, common payer coverage considerations, and guidance on where to locate relevant policy language. The publication highlights typical billing context for add-on laparoscopic colon procedures and summarizes implications for coding consistency across payers.
The audience will gain: a clear clinical and billing description of CPT code 44213, the typical site of service and service type, and an outline of what to expect when verifying coverage and coding rules with major national payers.

Billing Code Overview
CPT code 44213 describes a laparoscopic add-on procedure in which the surgeon mobilizes the splenic flexure during the same operative session as a partial colectomy. The mobilization of the splenic flexure is performed to prepare a suitable length of colon associated with a partial resection.
-
Service type: Surgical add-on procedure (laparoscopic mobilization of the splenic flexure)
-
Typical site of service: Hospital operating room or ambulatory surgical center during a laparoscopic partial colectomy

Clinical & Coding Specifications
Clinical Context
A typical patient is a 62-year-old adult presenting with a sigmoid or descending colon malignancy or complicated diverticular disease requiring a partial colectomy. After preoperative staging and optimization, the patient is taken to an operating room equipped for minimally invasive surgery. Under general endotracheal anesthesia, the surgeon performs a laparoscopic partial colectomy (segmental resection of the colon) and evaluates colonic length and mobility. When additional length is required to achieve a tension-free anastomosis, the surgeon mobilizes the splenic flexure laparoscopically during the same operative session to gain adequate colonic reach. Intraoperative steps include trocar placement, laparoscopic mobilization of lateral attachments and phrenicocolic ligaments, dissection of splenic flexure adhesions, and preservation of relevant vasculature as indicated. The procedure is billed as an add-on code because splenic flexure mobilization is performed in conjunction with the primary partial colectomy. Typical sites of service are an inpatient hospital operating room or an ambulatory surgical center for selected elective cases. Postoperative workflow includes recovery in PACU, early bowel function monitoring, pain control, and coordination of inpatient or outpatient follow-up care.
