CPT® Code 87502

Infectious agent detection by nucleic acid (DNA or RNA); influenza virus, for multiple types or sub-types, includes multiplex reverse transcription, when performed, and multiplex amplified probe technique, first 2 types or sub-types

The CPT® Code 87502 refers to a diagnostic test that detects the presence of influenza virus by analyzing nucleic acids, specifically DNA or RNA. This test is designed to identify multiple types or sub-types of the influenza virus, which are critical for determining the specific strain affecting a patient. Influenza viruses are categorized primarily into two main types: type A and type B. Within these categories, there are various subtypes, such as H1N1, H3N2, and H5N1, which can have significant implications for treatment and public health. The process of nucleic acid detection involves extracting genetic material from a laboratory specimen, which may include blood or other bodily fluids. The test utilizes a technique known as multiplex reverse transcription, which, when performed, allows for the simultaneous detection of multiple influenza strains. Additionally, the multiplex amplified probe technique is employed to enhance the sensitivity and specificity of the test. This method involves amplifying the extracted DNA or RNA to facilitate the identification of specific influenza types or subtypes. For coding purposes, CPT® Code 87502 is used for multiplex testing of the first two types or subtypes of influenza, while separate codes are designated for single types or additional subtypes, ensuring accurate billing and documentation in medical coding practices.
