Cash or insurance?

At the one hospital here that publishes insurer rates for this code, the cash price is not 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

AST is an enzyme found in the liver, muscles and heart. It is measured together with ALT to look for liver injury, and the ratio between them gives clues to the cause.

What the price covers

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