CPT® Code 87632

Infectious agent detection by nucleic acid (DNA or RNA); respiratory virus (eg, adenovirus, influenza virus, coronavirus, metapneumovirus, parainfluenza virus, respiratory syncytial virus, rhinovirus), includes multiplex reverse transcription, when performed, and multiplex amplified probe technique, multiple types or subtypes, 6-11 targets

The CPT® Code 87632 refers to a diagnostic test that detects infectious agents through the analysis of nucleic acids, specifically DNA or RNA, in respiratory specimens. This test is crucial for identifying various respiratory viruses, which may include adenovirus, influenza virus, coronavirus, metapneumovirus, parainfluenza virus, respiratory syncytial virus (RSV), and rhinovirus. The procedure involves collecting a respiratory specimen, which can be obtained through methods such as bronchoalveolar lavage, nasal wash, nasopharyngeal swab, or pleural fluid aspiration. Once the specimen is collected, it undergoes a sophisticated testing process that utilizes multiplex reverse transcription polymerase chain reaction (RT-PCR). This technique allows for the simultaneous extraction and amplification of nucleic acids from multiple types or subtypes of respiratory viruses. The amplified DNA or RNA fragments are then sized and analyzed to determine the specific viral types or subtypes present in the specimen. It is important to note that this code is specifically used when the test targets between 6 to 11 different types or subtypes of respiratory viruses. For tests targeting fewer types, such as 3-5, CPT® Code 87631 should be used, while CPT® Code 87633 is applicable for tests that target 12-25 types.
