Summary & Overview
CPT 45332: Colonoscopic Removal of Foreign Body from Rectum and Colon
CPT code 45332 denotes colonoscopic examination of the rectum and colon with identification and removal of foreign bodies using a flexible colonoscope. This endoscopic intervention is clinically significant because timely removal of obstructing or potentially injurious foreign objects can prevent perforation, bleeding, obstruction, and the need for more invasive surgery. As a procedure performed across inpatient and outpatient settings, it has implications for facility resource use, endoscopy unit throughput, and emergency care pathways.
Key payers in the national analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of coding intent and clinical context, typical sites of service, and the payer landscape relevant to coverage and billing practice. The publication also summarizes common modifiers and claims considerations, benchmarks for utilization where available, and notable policy or reimbursement updates that affect endoscopic foreign body removal. Clinical teams, billing professionals, and policy analysts will gain a concise reference to support appropriate coding, claims submission, and interpretation of payer policies related to colonoscopic foreign body extraction procedures.
Billing Code Overview
CPT code 45332 describes a diagnostic and therapeutic endoscopic procedure in which a provider examines the rectum and colon using a flexible colonoscope and identifies and removes foreign bodies that may obstruct or damage the intestine. The procedure combines visualization of the colorectal mucosa with endoscopic retrieval techniques to extract ingested or inserted objects.

Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after ingesting a small metallic object that is suspected to be lodged in the colon. He has intermittent abdominal pain, minimal rectal bleeding, and an abdominal radiograph showing a radiopaque foreign body localized to the colon. The gastroenterology team evaluates the patient, obtains informed consent, and performs bowel prep as clinically indicated. Under monitored anesthesia care in the endoscopy suite, the provider performs a diagnostic and therapeutic flexible colonoscopy to locate and retrieve the foreign body using endoscopic retrieval devices (e.g., snares, retrieval nets, or forceps). Post‑procedure, the patient is observed for complications (perforation, bleeding), receives discharge instructions, and follow‑up is arranged with gastroenterology.
