Frequently asked questions

How much does a colonoscopy cost without insurance?
Published hospital cash prices in this metro vary widely — see the Cash column in the table. Freestanding endoscopy centers (not listed here) are often cheaper than hospital outpatient departments.
Are screening colonoscopies free with insurance?
Preventive screening colonoscopies are generally covered without cost-sharing under most plans, but a diagnostic colonoscopy (what this page shows) or a screening that turns diagnostic can be billed differently. Check your plan.
Why do prices differ so much between hospitals in the same city?
Each hospital negotiates rates separately with each insurer. The federally required price files this page is built from show the same procedure differing by multiples between hospitals a few miles apart.
