Cash or insurance?

At 6 of 9 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 1 it is 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

A serum iron test measures the iron carried in the blood. It is usually ordered with iron-binding capacity and ferritin to check for iron deficiency or iron overload.

What the price covers

The price usually covers running the test. The blood draw (36415) is often billed as a separate line.

1 row held back from this comparison

It is priced below $1 or below a tenth of the national median for code 83540 ($49.95). 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.
