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
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
