While processing Lab & Pathology services, I find the provider billing CPT "82542" with multi-units for only 1 specimen(Urine). Whereas, multiple drugs/metabolites analysis was done. So the question is:

Can we bill multiple units for single specimen? As the code description says "Column chromatography, includes mass spectrometry, if performed (eg, HPLC, LC, LC/MS, LC/MS-MS, GC, GC/MS-MS, GC/MS, HPLC/MS), non-drug analyte(s) not elsewhere specified, qualitative or quantitative, EACH SPECIMEN"

Thanks
