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 prothrombin time (PT) test measures how long it takes blood to clot, and is reported with the INR, a standardized number. It is used to monitor warfarin and to check clotting before surgery or with liver disease.
What the price covers
The price usually covers the PT and INR result. The blood draw is often a separate charge; a fingerstick home or clinic INR check may be billed differently.
