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
In this endoscopic procedure a small balloon is passed through the nose and inflated to widen the natural opening of the maxillary (cheek) sinus. It is used for chronic or repeated sinusitis that does not improve with medicine.
What the price covers
The listed price usually covers the procedure for one side; the balloon device may be listed as a separate supply. The surgeon and any anesthesia are billed separately.
