CPT 44205: Laparoscopic Partial Colectomy with Ileocolic Resection

CPT code 44205 denotes a laparoscopic partial colectomy that includes resection of the terminal ileum and creation of an ileocolic anastomosis. This surgical procedure is a commonly performed abdominal operation for conditions that require removal of diseased segments of the right colon and distal ileum, and its laparoscopic approach is associated with shorter recovery times and reduced postoperative pain compared with open techniques. Nationally, this code is an important marker of operative management for colorectal disease and figures in utilization, payment, and quality discussions across payers.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical service represented by the code, the typical settings where the procedure is performed, and the payer landscape relevant to reimbursement and coverage policy. The publication outlines benchmark themes, expected billing considerations, and clinical context needed to interpret utilization patterns. Where input data is missing, the text notes that information is not available.

The audience will gain clarity on what CPT code 44205 represents, why it matters for surgical and payer stakeholders, and the types of benchmarks and policy updates that typically accompany analyses of laparoscopic colectomy coding and coverage.

Billing Code Overview

CPT code 44205 describes a laparoscopic partial colectomy with resection of the terminal ileum and an ileocolic anastomosis. This procedure involves minimally invasive removal of a segment of the colon along with the end of the ileum, followed by surgical connection of the remaining ileum and colon.

Clinical & Coding Specifications

Clinical Context

A typical patient is a 62-year-old with symptomatic ileocolic Crohn disease presenting with recurrent obstructing symptoms, chronic right lower quadrant pain, weight loss, and failure of medical management. After preoperative optimization including nutritional assessment and cessation of immunosuppressive biologic therapy per institutional protocol, the patient is scheduled for an elective laparoscopic partial colectomy with ileocecal resection and primary ileocolic anastomosis.

Preoperative workflow includes history and physical, informed consent documenting risks of bleeding, infection, anastomotic leak, and conversion to open surgery, bowel preparation per surgeon preference, and anesthesia evaluation. Intraoperative workflow begins with laparoscopic access, diagnostic laparoscopy, mobilization of the terminal ileum and right colon, resection of the diseased segment, and creation of a hand-sewn or stapled ileocolic anastomosis. The procedure may be converted to an open right hemicolectomy if visualization, adhesions, or hemostasis necessitate. Postoperative care includes inpatient monitoring for return of bowel function, pain control, DVT prophylaxis, and discharge planning with outpatient follow-up for pathology review and wound check.
