When performing an amplified probe test that detects respiratory syncytial virus (RSV) subtypes A and B and reports a single result (positive or negative), is code 87801 (Infectious agent detection by nucleic acid (DNA or RNA), multiple organisms; amplified probe(s) technique) the appropriate code to report? Or should code 87798 (Infectious agent detection by nucleic acid (DNA or RNA), not otherwise specified; amplified probe technique, each organism) be reported? ...

Article Overview
This coding article explains reporting considerations for amplified nucleic acid probe testing related to respiratory syncytial virus subtype analysis. It is relevant to laboratory coders, billing staff, and compliance teams who need to understand how result structure and organism-level reporting affect coding choices. The article also references a modifier used when separate results are reported for different species or strains.
Why This Topic Matters
Laboratory test reporting can change how a claim is coded, especially when a single combined result is reported versus separate organism-level results. Understanding the article helps reduce reporting errors and supports consistent coding practices for respiratory virus molecular testing.
