CPT 45334 Sigmoid Endoscopic Hemostasis Reimbursement | OpenPayer

Summary & Overview

CPT 45334: Sigmoid Colon Endoscopic Evaluation with Hemostasis

CPT code 45334 represents an endoscopic procedure in which the rectum and sigmoid colon are examined with a flexible colonoscope to identify the source of internal bleeding and bleeding in the sigmoid colon is controlled by any method. This procedure carries clinical importance for acute lower gastrointestinal hemorrhage, enabling both diagnosis and immediate therapeutic intervention to reduce risk of ongoing blood loss, need for transfusion, and urgent surgery. Nationally, the code is relevant across hospital outpatient departments, ambulatory surgery centers, and emergency endoscopy services.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find clinical context for when the procedure is used, typical sites of service, and which payer types commonly reimburse for endoscopic hemostasis in the sigmoid colon. The publication provides benchmarks for utilization and reimbursement patterns where available, discusses documentation and coding considerations tied to endoscopic diagnosis and intervention, and summarizes policy or coverage updates that affect access to urgent endoscopic hemostasis. Data not available in the input is noted explicitly where applicable.

Billing Code Overview

CPT code 45334 describes a diagnostic and therapeutic procedure in which a provider examines the rectum and sigmoid colon using a flexible colonoscope to identify a source of internal bleeding and controls bleeding in the sigmoid colon by any method. This procedure is an endoscopic evaluation with an intervention to achieve hemostasis in the sigmoid colon.

Service type: Endoscopic diagnostic and therapeutic procedure (flexible sigmoidoscopy/colonoscopy segment with hemostasis)
Typical site of service: Ambulatory surgery center or hospital endoscopy suite

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult who presents to the emergency department or endoscopy unit with acute lower gastrointestinal bleeding, hematochezia, or significant iron-deficiency anemia with suspected source in the sigmoid colon. The patient often has hemodynamic monitoring, intravenous access, laboratory studies (CBC, coagulation panel), and informed consent for endoscopy. The gastroenterologist performs a flexible sigmoidoscopy/colonoscopy using a flexible colonoscope to examine the rectum and sigmoid colon, identify active bleeding sources (eg, diverticula, angiodysplasia, ulceration, bleeding polyp), and perform endoscopic hemostasis by methods such as injection, thermal coagulation, mechanical clipping, or topical hemostatic agents. The procedure is typically performed in an endoscopy suite or operating room under moderate sedation or monitored anesthesia care; nursing and anesthesia staff document sedation, vital signs, and procedural interventions. Post-procedure monitoring includes observation for recurrent bleeding, perforation, or sedation-related complications before discharge or admission for further care.
