Summary & Overview
CPT 46612: Anoscopy with Removal of Multiple Anal/Rectal Lesions
CPT code 46612 represents an anoscopy procedure with removal of multiple tumors, polyps, or lesions using hot biopsy, bipolar cautery, or snare techniques. This code captures a common anorectal therapeutic endoscopic service used to diagnose and treat symptomatic or suspicious mucosal lesions in the anal canal and distal rectum. Nationally, accurate coding for this procedure affects clinical documentation, billing consistency, and Medicare and commercial payer reimbursement for ambulatory surgical and outpatient settings.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find concise information on the clinical context of the procedure, typical sites of service, commonly reported modifiers, and the set of payers most relevant for coverage and claims adjudication. The publication also outlines benchmarks and policy considerations relevant to payers and providers, clarifies coding scope for multiple lesion removals, and highlights operational implications for ambulatory surgical centers and hospital outpatient departments.
This summary is intended for billing managers, surgical providers, and revenue cycle teams seeking a national view of how CPT code 46612 is used and reimbursed across major payers, and what operational and documentation elements are most important for correct claim submission.
Billing Code Overview
CPT code 46612 describes an anoscopy with removal of multiple tumors, polyps, or lesions using techniques such as hot biopsy, bipolar cautery, or snare. The procedure involves insertion of a small, rigid, tubular instrument (anoscope) for direct visualization of the anal canal and distal rectum, followed by excision or destruction of multiple mucosal lesions.
-
Service type: Endoscopic procedural excision of multiple anorectal lesions
-
Typical site of service: Ambulatory surgical center or hospital outpatient department, and may be performed in an office procedure room when appropriate
Clinical & Coding Specifications
Clinical Context
A typical patient is a 58-year-old adult who presents to a colorectal clinic with rectal bleeding and/or palpable rectal lesions identified on digital rectal exam. After history and focused examination, the provider schedules an in-office anoscopy under direct visualization using a small rigid anoscope. During the procedure the clinician inspects the distal anal canal and rectum, identifies multiple small polyps or exophytic lesions, and removes them using hot biopsy forceps, bipolar cautery, or a snare technique. Biopsies or polypectomy specimens are submitted for histopathology. Hemostasis is achieved with cautery as needed. The clinical workflow includes pre-procedure consent, brief procedural sedation or local anesthesia as indicated, sterile setup of anoscope and electrosurgical or snare equipment, lesion removal, specimen labeling and pathology submission, post-procedure recovery and discharge instructions, and documentation of findings, technique, complications, and specimen handling.
