Medical Code 920: Virology Laboratory Report

Code 920 (in legacy or proprietary coding systems) designates a virology laboratory report—documenting results of tests detecting viral pathogens in patient specimens (blood, CSF, respiratory swabs, stool, tissue).

Typical Content

• Virus identified (e.g., influenza, HSV, VZV, HIV, HCV, SARS-CoV-2)
• Method: PCR/NAAT, culture, antigen, serology (IgM/IgG), sequencing
• Quantitative results (viral load) if applicable
• Interpretation: detected/not detected, titer, resistance mutations
• Specimen source, collection date/time

Current Standard

Modern systems use LOINC (test) + SNOMED CT (result) or CPT for billing. Code 920 may persist in older interfaces or specific institutional schemas.
