Drug cpt coding - 80101

CPT Coding and Drugs of Abuse Testing Recommendations

It is our recommendation based on the currently available information that the appropriate CPT code
for on-site drugs of abuse test kits is;

80101* – Drug Screen, qualitative; single drug class method (e.g., immunoassay, enzyme assay)
*add QW modifier if billing Medicare/Medicaid

For code 80101, each single drug class method tested and reported is to be counted as one drug
class. If a sample is analyzed by five separate class-specific immunoassays and reported separately,
code 80101 should be reported five times. Similarly, if a sample is run on a rapid assay kit composed
of five class-specific immunoassays in a single kit, and the five classes are reported separately, code
80101 should again be reported five times.
