CPT 44700 Small Bowel Barrier — Reimbursement | OpenPayer

Summary & Overview

CPT 44700: Small Bowel Barrier Placement to Protect Pelvis

CPT code 44700 identifies a surgical procedure to place a physical barrier between the small intestine and the pelvis to protect the bowel from radiation damage. Clinically, this procedure matters nationally as an intervention to reduce acute and chronic radiation enteritis for patients undergoing pelvic radiation for malignancies or other pelvic conditions. It is relevant to surgical, radiation oncology, and gastrointestinal care teams.

Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise review of clinical context, common settings where the service is delivered, and the payer landscape relevant to coverage and billing practices. The publication outlines benchmark considerations, typical modifier usage patterns (listed separately), and how the procedure is documented for claims.

This summary provides readers with the clinical purpose of the code, the typical sites of service, and what to expect in payer discussions and claims workflows. Data not available in the input is noted where applicable in detailed sections.

Billing Code Overview

CPT code 44700 describes a surgical procedure in which the provider places a barrier between the small intestine and the pelvis to protect the bowel from damage during pelvic radiation therapy. This service is typically performed as a surgical intervention to reduce radiation enteritis risk by physically separating mobile small bowel from the radiation field.

Service type: Surgical placement of pelvic-small bowel barrier
Typical site of service: Operating room or ambulatory surgical center, performed by a surgeon with appropriate training in abdominal or pelvic procedures

Clinical & Coding Specifications

Clinical Context

A typical patient scenario involves an adult undergoing pelvic external-beam radiation for gynecologic or rectal malignancy (for example, postoperative cervical cancer or recurrent rectal cancer) where prior abdominal surgery or planned radiation port placement risks exposing loops of small intestine to high-dose radiation. The multidisciplinary workflow begins with consultation between radiation oncology and surgical teams. The surgeon evaluates the patient preoperatively, reviews imaging to localize small-bowel loops relative to the pelvis, and plans a minimally invasive or open operative approach. In the operating room under general anesthesia, the surgeon creates and places a physical barrier (peritoneal spacer, omental flap, or synthetic absorbable mesh) between the small intestine and pelvic radiation field to reduce bowel dose and subsequent radiation enteritis. Postoperative care includes routine surgical monitoring, pain control, bowel function assessment, and coordination with radiation oncology to resume or begin planned radiation therapy once the surgical site has sufficiently healed.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`C53.9`	Malignant neoplasm of cervix uteri, unspecified	Cervical cancer commonly requires pelvic radiation; spacer placement protects small bowel from pelvic radiation fields.
`C20`	Malignant neoplasm of rectum	Rectal cancer treated with pelvic radiotherapy may require bowel displacement to reduce enteric toxicity.
`C54.9`	Malignant neoplasm of corpus uteri, unspecified	Endometrial cancers requiring adjuvant pelvic radiation may prompt spacer placement in selected cases.
`C79.2`	Secondary malignant neoplasm of liver	Metastatic pelvic disease with planned pelvic radiation may necessitate small-bowel protection if radiation fields extend inferiorly.
`Z92.3`	Personal history of irradiation	History of prior irradiation increases risk of cumulative bowel toxicity and supports use of spacer for re-irradiation planning.

Related CPT Codes

CPT Code	Description	Relationship to This Procedure
`44120`	Enterolysis (separate procedure)	May be performed before or during spacer placement when extensive adhesions tether small bowel to the pelvis and require lysis to allow safe mobilization of bowel away from the radiation field.
`49560`	Repair of initial incisional or ventral hernia with graft or mesh	Performed in patients with prior abdominal wall defects where mesh placement or revision is required in the same operative session.
`58661`	Laparoscopy, surgical; with removal of adnexal structures (partial or total)	Common concurrent procedure in gynecologic oncology cases where adnexal surgery and spacer placement occur together.
`19318`	Implantation of spacer (pelvic) — note: CPT does not have a specific pelvic spacer code beyond `44700`	Use as contextual reference; `44700` is the code describing placement of a barrier between small intestine and pelvis for radiation protection.
`49200`	Repair of parastomal hernia	May be performed in complex pelvic operations when stoma-related issues are addressed during the same hospitalization.
