Cash or insurance?
At the one hospital here that publishes insurer rates for this code, the cash price is not 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 flexible sigmoidoscopy uses a thin camera to look at the rectum and the lower part of the colon, not the whole colon. It is used to check symptoms like bleeding or changes in bowel habits, and sometimes for screening.
What the price covers
The listed price usually covers the procedure. The doctor's fee may be billed separately, and a biopsy or polyp removal changes the code and adds pathology.
