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.
