Colonoscopy cost without insurance
The median cash price for Colonoscopy is $1,443.50 across 872 US hospitals that publish a self-pay price. Most hospitals (the middle 80%) charge between $451.66 and $3,791.75.
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.

“Most charge” is the middle 80% of hospitals (10th to 90th percentile), so one mistyped line in a hospital file cannot stretch it. Each hospital counts once, at its lowest outpatient cash price for the code. “Medicare” is Medicare's 2026 national base rate for the same service outside a hospital stay, including the patient's share (the hospital outpatient, lab or hospital clinic rate); “median 3×” means the median cash price is three times that rate.

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.
Questions
How much does a colonoscopy cost without insurance?
The total is the facility fee in the table plus the gastroenterologist, anesthesia and, if tissue is removed, pathology; the bowel-prep medicine is bought separately at a pharmacy. Ask each provider for its self-pay price, or ask whether a bundled cash package is offered.
Why was my screening colonoscopy billed as a different code?
If a polyp is removed or a biopsy is taken, the procedure is billed under a different code. Under federal rules most private plans must cover a screening colonoscopy without cost-sharing, including polyp removal during it and a follow-up colonoscopy after a positive stool test.
Is a stool test an alternative to a colonoscopy?
For people at average risk without symptoms, a yearly FIT (82274) is one of the screening options guidelines accept, and it is a lab test done with a kit at home. A positive result needs a follow-up colonoscopy, and a stool test does not suit people with symptoms or high risk, so ask a clinician which option fits.
