CPT 44130: Intestinal Anastomosis, With or Without Stoma

CPT code 44130 denotes a surgical intestinal anastomosis procedure in which a clinician connects two segments of bowel, with the option of creating a stoma. This code captures a common component of colorectal and general abdominal surgery and is used across inpatient and outpatient surgical settings. Nationally, accurate coding for 44130 matters for appropriate case mix reporting, resource allocation, and surgical quality measurement.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for the procedure, typical sites of service, common billing modifiers associated with surgical services, and national payer coverage considerations. The publication outlines benchmark metrics and policy-relevant notes that affect claims adjudication and hospital reporting. Additionally, the content will clarify coding scope and identify areas where coding variation commonly occurs.

This resource is intended for revenue cycle professionals, surgical coders, clinical administrators, and policy analysts seeking a national-level briefing on CPT code 44130 and its implications for billing and surgical service classification.

Billing Code Overview

CPT code 44130 describes a surgical procedure in which the provider creates an anastomosis between two segments of the intestines. The procedure may be performed with or without bringing a segment of intestine to the skin to create a stoma.

Service type: Intestinal anastomosis / bowel resection-related anastomosis surgery
Typical site of service: Hospital operating room or inpatient surgical suite; may also occur in an ambulatory surgical center when clinically appropriate

Clinical & Coding Specifications

Clinical Context

A 64-year-old patient with a history of colorectal cancer undergoes segmental small bowel resection with creation of an intestinal anastomosis. The patient presents preoperatively with an obstructing left-sided colon tumor causing subacute bowel obstruction and failure of conservative management. Preoperative workflow includes surgical evaluation, imaging (CT abdomen/pelvis), bowel preparation as indicated, informed consent, pre-anesthesia assessment, and perioperative antibiotic prophylaxis. Intraoperative workflow: laparotomy or laparoscopic exploration, resection of the diseased bowel segment, hemostasis, creation of a primary end-to-end or side-to-side intestinal anastomosis using staples or hand-sewn technique, assessment of anastomotic perfusion, and optional formation of a diverting stoma if indicated. Postoperative workflow: recovery in PACU, inpatient monitoring for return of bowel function, pain control, DVT prophylaxis, wound care, and discharge planning with follow-up for pathology and possible adjuvant therapy.

Coding Specifications

Modifier	Description	When to Use
`26`	Professional component	Use when reporting only the physician’s professional component for separately payable technical services related to the procedure (rare for operative CPT).
`50`	Bilateral procedure	Use when two intestinal anastomoses are performed bilaterally or duplicated segments require distinct procedures reported as bilateral.
`51`	Multiple procedures	Use when `44130` is reported with additional unrelated surgical procedures during the same operative session.
`52`	Reduced services	Use when the documented procedure was partially reduced or not completed as planned.
`53`	Discontinued procedure	Use when the operation is started but discontinued due to extenuating circumstances.
`54`	Surgical care only	Use when reporting only the surgeon’s portion when another provider reports pre- or post-operative care separately.
`55`	Postoperative management only	Use when the surgeon provides only postoperative care for a procedure performed by another surgeon.
`58`	Staged or related procedure or service by the same physician during the postoperative period	Use when an anticipated staged reoperation for the anastomosis is planned and performed within the global period.
`59`	Distinct procedural service	Use when a separate and distinct anastomotic procedure is performed in addition to other services that would usually be bundled.
`62`	Two surgeons	Use when two surgeons work together as primary surgeons performing distinct portions of the intestinal resection and anastomosis.
`63`	Procedure performed on infants less than 4 kg	Use only when patient meets weight criteria and code-specific guidelines apply.
`79`	Unrelated procedure or service by the same physician during the postoperative period	Use when an unrelated procedure is performed during the global period.
`80`	Assistant surgeon	Use when a surgical assistant is documented and paid separately.
`AS`	Physician assistant, nurse practitioner, or clinical nurse specialist services for assistant at surgery	Use when an advanced practice clinician functions as the assistant at surgery where allowed.

Taxonomy Code	Specialty	Notes
208100000X	General Surgery	Most common specialty performing intestinal anastomosis.
