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
The adjuvanted flu shot contains an added ingredient (MF59) that strengthens the immune response. It is one of three flu vaccines the CDC prefers for people 65 and older.
What the price covers
The price is for the vaccine dose. Giving the shot is usually a separate line (code 90471 for the first vaccine of the visit); Medicare bills use G0008 instead.
