Summary & Overview

CPT 45350: Hemorrhoid Band Ligation via Flexible Sigmoidoscopy

CPT code 45350 denotes endoscopic band ligation of hemorrhoids using a flexible sigmoidoscope. This minimally invasive outpatient procedure is a common therapeutic option for symptomatic internal hemorrhoids and is performed in ambulatory surgical centers and endoscopy suites. Nationally, it is significant because it represents a frequently billed colorectal procedure with implications for outpatient procedural capacity and payer coverage policies.

Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context and typical sites of service, plus what to expect in payer coverage and billing practice. The publication covers benchmarks for utilization and reimbursement, relevant policy updates affecting outpatient endoscopic procedures, and clinical considerations that influence coding and site-of-service selection.

This summary equips clinicians, billers, and policy analysts with the essential context for CPT code 45350, helping stakeholders understand where the procedure is commonly performed, which payers are most relevant, and the types of analyses (utilization benchmarks, policy changes, and clinical guidance) presented in the full publication.

Billing Code Overview

CPT code 45350 describes the endoscopic ligation of a structure such as a hemorrhoid using a flexible band delivered through a flexible sigmoidoscope. This procedure involves placing a tight band around the base of hemorrhoidal tissue to cut off blood supply, typically performed to treat symptomatic internal hemorrhoids.

Service type: Endoscopic therapeutic procedure (band ligation)
Typical site of service: Ambulatory surgical center or outpatient endoscopy suite using a flexible sigmoidoscope

Clinical & Coding Specifications

Clinical Context

A typical patient is an adult presenting to an outpatient gastroenterology or colorectal surgery clinic with symptomatic internal hemorrhoids causing bleeding, prolapse, or discomfort. After history and limited digital/anoscopic examination, the provider determines that rubber band ligation is appropriate for I–II or selected III degree internal hemorrhoids. The patient is scheduled for an in-office flexible sigmoidoscopy-assisted procedure to place a rubber band around the hemorrhoidal pedicle using a flexible band ligator. A consent discussion covers the procedure, expected discomfort, potential complications (bleeding, pain, infection, urinary retention), and post-procedure care including sitz baths and stool softeners.

The clinical workflow: the patient arrives to an ambulatory endoscopy or office-based procedure room; vital signs and indications are confirmed; topical anesthesia and possible minimal sedation or local anesthetic are applied per clinic protocol; a flexible sigmoidoscope is inserted to visualize the rectum and distal sigmoid; the hemorrhoid is suctioned into the banding device and a rubber band is deployed; hemostasis and visualization are confirmed; the patient is observed briefly and discharged with aftercare instructions and follow-up arranged for symptom assessment and possible additional banding sessions.
