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
Tdap protects against tetanus, diphtheria and whooping cough (pertussis). Adults who never had it get one dose, pregnant women get one in each pregnancy, and it can replace a tetanus booster.
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).
