CPT code 85610
What does CPT code 85610 mean on a medical bill?
This blood test measures how quickly your blood clots, and it is standard for anyone on a blood thinner, anyone who is bleeding, and before many procedures. It is billed per run, so a visit that checked it before and after treatment will carry two lines. It is often ordered together with a second clotting test, and seeing both is normal rather than a duplicate.
What should I watch out for with CPT code 85610?
- More clotting tests billed than results in your lab report
- The same test billed by both the hospital lab and an outside lab company
- A test billed on a day you had no blood drawn — compare the dates against your draw record
