About partial thromboplastin time (blood clotting test)

CPT 85730 is a partial thromboplastin time (PTT or aPTT), a clotting test that checks a different part of the clotting cascade from prothrombin time. It is used to monitor heparin, to investigate unexplained bleeding or bruising, and before surgery. One blood draw.

What the price covers

The laboratory analysis only. The blood draw is a separate small charge. It is often ordered together with prothrombin time (85610); the two are separate codes and separate prices.

Why prices vary

The test runs on automated coagulation analyzers and costs a laboratory a few dollars. Hospital list prices range from under $10 to over $150 for the same result. Independent laboratories are typically far cheaper.

Questions to ask

  • What is the self-pay price for 85730, and is PT (85610) also being billed?
  • Is the blood draw extra?
  • Can the sample be sent to an outside laboratory?
