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
The partial thromboplastin time (PTT or aPTT) test measures how long it takes blood to clot through a different pathway than the PT test. It is used to check for bleeding disorders, before surgery, and to monitor heparin.
What the price covers
The price usually covers the PTT test. The blood draw is often billed separately.
