Cash or insurance?
At 2 of 2 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at none is it 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
The MenACWY vaccine protects against four types of meningococcal bacteria that cause meningitis and bloodstream infections. It is routine at ages 11 to 12 with a booster at 16, and many colleges require it for students living in dorms.
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).
1 row held back from this comparison
It is priced below $1 or below a tenth of the national median for code 90734 ($261.38). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
