Inpatient: lowest $10.50, median $31.00, highest $91.50 — a 8.7× difference within the same market.

As an outpatient, the same code is billed by 22 facilities here, median $29.25 — that is the price to compare if you are not being admitted.

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.

3 rows held back from this comparison

They are priced below $1 or below a tenth of the national median for code 85610 ($32.92). Such a line is almost always a physician's fee billed separately, an assistant's share or a placeholder — a real charge, but not the price of the procedure itself.
