Creatinine Clearance

Karin Posted Tue 04th of December, 2012 15:48:56 PM

We have a question on Creatinine Clearance. You need to do a serum creatine and a urine creatine to do the creatinine clearance calculation. We charge for the serum creatinine 82565 because sometimes we use the result from a test we ran previously. We do not separately charge for the urine creatinine unless it has been specifically ordered. Is that a correct process...please list the codes that you would assign if the doctor has only ordered a creatinine clearance.

Because 82575 (Creatinine; clearance) includes a urine creatinine, you should never report an additional 82570 (Creatinine; other source) for the urine test. If the lab performs a creatinine for a source other than urine, such as peritoneal fluid, on the same day as a creatinine clearance, you'll have to override the edit pair by appending modifier -59 Distinct procedural service) to 82570. NCCI also bundles 82565 (Creatinine; blood) with 82575.
