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 and 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
An open gastric bypass makes a small stomach pouch and connects it to the small intestine through one larger cut in the abdomen instead of small laparoscopic cuts. Surgeons use it mainly when laparoscopy is not possible, such as after earlier abdominal operations.
What the price covers
The facility price usually covers the operating room and recovery and may not include the hospital stay. The surgeon, anesthesia, pre-surgery tests and follow-up visits are usually billed separately. An open operation usually means a longer hospital stay.
