Hospital The hospital that published the price, its city and the line exactly as written in its price file.

Cash price The hospital's own price for a patient paying without insurance (“discounted cash” in its price file). Hospitals must publish it under federal law, 45 CFR 180.50. Call to confirm it before booking. More

List price The hospital's full chargemaster price (“gross charge”) before any discount. Almost nobody pays it; the gap to the cash price shows what the self-pay discount is worth. More

Insurers pay The lowest and highest rates this hospital has agreed with insurance plans for the same item, from its price file. If the cash price is below what your plan pays and you have not met your deductible, paying cash can cost you less. More

Off list How much lower the cash price is than the list price.

Outpatient: lowest $365.68, median $365.68, highest $684.29 — a 1.9× difference within the same market.

As an inpatient, the same code is billed by 4 facilities here, median $365.68. Inpatient and outpatient prices are not comparable and are kept on separate pages: the inpatient charge covers admission, not the same purchase.

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

This is the larger dose (100 mg) of nirsevimab (Beyfortus), an antibody shot that protects infants from severe RSV. Babies weighing 5 kg (11 lb) or more in their first RSV season get this dose, and high-risk toddlers get two of them in their second season.

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, 90472 for each additional one).

5 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 90381 ($980.10). 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.
