Cash or insurance?
At 13 of 13 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 3 it is below every plan's rate. 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
This is a screening colonoscopy for someone without symptoms who is at high risk of colorectal cancer, for example because of a close relative with the disease, earlier polyps or inflammatory bowel disease. G0105 is a Medicare code; for people at high risk Medicare covers it as often as every 2 years.
What the price covers
The facility price usually covers the procedure room and recovery. The gastroenterologist, anesthesia, the bowel-prep medicine and any pathology are usually billed or bought separately.
