CPT Code 45385: Colonoscopy with Polypectomy using Snare Technique

It includes a complete colonoscopy and removal of one or more polyps using a snare loop, often with electrocautery. It is considered a therapeutic service.

If a screening colonoscopy results in snare polyp removal, report CPT 45385 with modifier PT (Medicare) or modifier 33 (commercial) to indicate the screening intent.

Use the screening diagnosis code if the procedure began as a screening, and include a secondary code that would also be used. Always confirm with payer-specific policies.
