Cash or insurance?
At 13 of 18 hospitals that publish insurer rates for this code here, the cash price is below the highest rate a health plan has negotiated, and at 2 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
A D-dimer test measures a protein fragment released when a blood clot breaks down. A normal result helps rule out a clot in the legs or lungs when the chance of one is low.
What the price covers
The price usually covers running the test. The blood draw (36415) is often billed as a separate line.
