Cash or insurance?
At the one hospital here that publishes insurer rates for this code, the cash price is below the highest rate a health plan has negotiated. If you have insurance but have not met your deductible, you usually pay your plan's negotiated rate, which falls somewhere in the "Insurers pay" column. Paying cash can cost less, but a cash payment usually does not count toward your deductible. Ask the hospital for both numbers before you book.
What it is
A colonoscopy uses a long, flexible camera to look at the inside of the entire colon (large intestine). The diagnostic version, with no tissue taken, is used to look into symptoms like bleeding or changes in bowel habits and is also used for screening.
What the price covers
The facility price covers the procedure room and recovery. The gastroenterologist's fee, anesthesia and the bowel-prep medicine are usually billed or bought separately.
