CPT code 81003
What does CPT code 81003 mean on a medical bill?
This is a urine test read by a machine: the dipstick strip that checks for things like blood, sugar, protein, and signs of infection, with nobody looking at the sample under a microscope. There is a separate code for the version that includes the microscope, and another for a culture that grows bacteria over a couple of days. Your bill should reflect which of those actually happened to your sample.
What does CPT code 81003 usually cost?
Charged per sample. Two urine lines from one cup usually means the strip reading and a microscope reading were billed as separate services, so ask for the lab report before paying both.
What should I watch out for with CPT code 81003?
- A separate microscopic exam billed on top of this one for the same cup
- A urine culture billed automatically when the record does not show one was ordered
- More urine tests billed than samples you gave
