 | Coding 


We have outpatient lab orders on patients that frequently have a host of lab tests performed including Microalbumin/Creatinine Ratio and Urine Drug Screen, CPT® codes 82570, 82043, 80307. There are separate orders & results for all 3 tests.  All may have the same diagnoses or different diagnoses.


I have read the NCCI edit about specimen validity, but in this case, these tests appear to be ordered for specific diagnoses, they have separate orders and results. Would 59 be appropriate on 82570?



Yes, modifier 59 can be used when CPT® code 82570 (urine creatinine) is ordered and resulted separately, and when the urine creatinine is “not” performed for specimen validity testing.


To support this opinion, we used the NCCI policy statement you referenced above (NCCI Policy Manual, chapter X, section E.2, page X-7) Link
