Cash or insurance?
At 20 of 22 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 3 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
An alkaline phosphatase test measures an enzyme from the liver, bile ducts and bones. High levels suggest a blocked bile duct, liver disease or bone disease.
What the price covers
The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
