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
A total T4 test measures all the thyroxine hormone in the blood, both bound and free. Most doctors now order free T4 (84439) instead, which is less affected by pregnancy and medicines.
What the price covers
The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
