Drug Screening Assays

Blue Cross utilizes the following billing guidelines for drug screening assays for Laboratory providers. Laboratory Providers are classified as independent allied providers who are CLIA certified for the sole purpose of performing laboratory services. When performing urine drug screens using instrumented systems, report the following codes (limited to one unit per date of service): • 80100 • G0431

When billing more than one unit of the following code, documentation upon appeal must support that separate tests were performed to detect the absence or presence of the different drug classes tested. Blue Cross only reimburses for one test when a single testing mechanism is used to screen for multiple drug classes: • 80101

Routine periodic audits are performed. Discovery of inappropriate billing may result in a more detailed review and possible recoupment of overpayment.
