Summary & Overview
CPT 45388: Flexible Colonoscopy for Lesion Destruction
CPT code 45388 designates flexible colonoscopy with destruction of one or more tumors, polyps, or other lesions. This therapeutic endoscopic procedure is commonly performed in ambulatory surgical centers and hospital outpatient departments and is clinically significant for colorectal disease management, including polypectomy and lesion ablation. Nationally, this code is used to capture procedural interventions aimed at removing or destroying lesions identified during diagnostic colonoscopy, contributing to cancer prevention and symptomatic lesion control.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The summary addresses coverage and billing practice implications as they relate to procedural coding, common modifiers, and typical sites of service.
Readers will learn the clinical context of CPT code 45388, the service setting where it is typically performed, and the types of lesions targeted by the procedure. The publication provides benchmarking and policy-relevant information, explains payer coverage patterns, and summarizes operational considerations for billing and coding workflows. Data not available in the input is noted where specific payer policies, associated taxonomies, ICD-10 diagnoses, and related codes would normally be detailed.
Billing Code Overview
CPT code 45388 describes a flexible colonoscopy procedure performed to destroy one or more tumors, polyps, or other lesions. The service includes therapeutic destruction of mucosal or submucosal lesions and may involve guide wire passage and dilation of the target site before or after lesion ablation when performed as part of the procedure.
-
Service type: Therapeutic endoscopic procedure (flexible colonoscopic lesion destruction)
-
Typical site of service: Ambulatory surgical center or hospital outpatient department where flexible colonoscopy with endoscopic lesion ablation is performed
Clinical & Coding Specifications
Clinical Context
A 68-year-old patient with intermittent rectal bleeding and a positive fecal immunochemical test undergoes a diagnostic flexible colonoscopy. During the examination the endoscopist identifies one or more sessile polyps and a friable neoplastic-appearing lesion in the sigmoid colon. The provider performs endoscopic tumor destruction and polypectomy using electrocautery and snare technique, with possible pre- and post-dilation of a partially obstructing lesion and optional guide wire passage to access the site. The typical clinical workflow includes pre-procedure evaluation and consent, moderate sedation administered by an anesthesia professional or endoscopist, colonoscopic inspection, lesion identification and treatment (ablation, snare polypectomy, or tumor debulking), hemostasis as needed, and post-procedure recovery with discharge instructions.
Typical site of service: Ambulatory surgery center or hospital outpatient department.
Service type: Therapeutic flexible colonoscopy with lesion destruction (endoscopic tumor/lesion ablation or removal).
