Outpatient: lowest $10.00, median $20.07, highest $610.83 — a 61.1× difference within the same market.

As an inpatient, the same code is billed by 21 facilities here, median $20.33. 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 30 of 37 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 10 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

Free T3 is the active thyroid hormone not bound to proteins. It is usually checked after TSH (84443) and free T4 (84439), mainly when an overactive thyroid is suspected.

What the price covers

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