COVID-19 October Update (October 2020)

Why This Topic Matters

The article matters because it documents a set of CPT and PLA updates used to distinguish SARS-CoV-2 testing from other respiratory virus testing and to clarify reporting guidance for infectious agent studies. These changes affect laboratory compliance, claim accuracy, and consistent reporting across COVID-19-related diagnostic services.
