A colonoscopy examines the whole colon with a flexible camera, and one procedure usually produces several bills: the facility, the gastroenterologist, anesthesia, and pathology if tissue is removed. The key price detail is that a planned exam can become a biopsy (45380) or polyp removal (45385) during the procedure, which changes the code and adds a pathology charge.

Paying cash: what to do
- Ask for a self-pay quote that covers the facility, the gastroenterologist and anesthesia, and ask which of them bill separately.
- Ask for prices for 45380 and 45385 as well, since no one knows in advance whether a biopsy or polyp removal will be needed.
- Ambulatory surgery centers often charge less than hospital outpatient departments for the same colonoscopy, so ask the gastroenterologist where they perform it.
