Summary & Overview
CPT 44005: Lysis of Adhesions, Colon and Intra‑abdominal Structures
CPT code 44005 represents surgical lysis of adhesions involving the colon and other intra‑abdominal structures, performed to relieve pain or bowel obstruction caused by fibrous bands from prior surgery, trauma, or pelvic inflammatory disease. This operative code captures work for complex intra‑abdominal adhesion release using multiple techniques and is relevant to general surgeons and colorectal specialists. Nationally, it is an important procedural code for managing adhesive small‑bowel obstruction and chronic post‑operative abdominal pain.
Key payers commonly referenced for coverage and reimbursement patterns include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers can expect a concise overview of clinical context, typical sites of service (hospital OR or ambulatory surgical center), and common billing considerations associated with operative adhesion lysis. The publication outlines expected service definitions, common modifiers (listed separately), and areas where policy language or documentation practices commonly affect claims adjudication.
This summary equips clinical billing staff, surgeons, and policy analysts with a clear description of what CPT code 44005 represents, why it is used, and what topics to review when preparing claims or assessing coverage — including procedure indications, typical settings, and documentation elements that support medical necessity.
Billing Code Overview
CPT code 44005 describes surgical lysis of adhesions involving the colon and other intra-abdominal structures. The procedure frees fibrous bands (adhesions) that form after prior surgery, trauma, or pelvic inflammatory disease and that can cause abdominal pain or bowel obstruction. The description indicates the use of a combination of techniques to release adhesions.
-
Service type: Operative abdominal surgery for adhesion lysis
-
Typical site of service: Hospital operating room or ambulatory surgical center for intra-abdominal procedures
Clinical & Coding Specifications
Clinical Context
A 54-year-old female with a history of prior abdominal hysterectomy presents with intermittent crampy abdominal pain, bloating, and episodic partial small-bowel obstruction. Imaging (CT abdomen/pelvis) demonstrates adhesive bands and focal kinking of the colon without a clear mass. The patient is scheduled for operative lysis of adhesions to relieve symptomatic obstruction and chronic pain. The procedure is performed in an operating room under general anesthesia. The surgical team performs exploratory laparoscopy with careful identification of adhesions between the colon, small intestine, and anterior abdominal wall. Adhesiolysis is accomplished using sharp dissection and electrocautery, with conversion to an open approach if dense adhesions or unanticipated pathology are encountered. Hemostasis is achieved, the bowel is inspected for iatrogenic injury, and a drain is left if indicated. The typical clinical workflow includes preoperative evaluation, informed consent documenting risks of enterotomy and need for possible bowel resection, intraoperative documentation of adhesion locations and techniques used, and postoperative monitoring for return of bowel function and signs of infection or leak. Usual sites of service are hospital inpatient or ambulatory surgical center depending on patient comorbidity and anticipated complexity.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work required to perform adhesiolysis is substantially greater than typical for due to extensive dissection. |
