CPT® Code 87539

Infectious agent detection by nucleic acid (DNA or RNA); HIV-2, quantification, includes reverse transcription when performed

The CPT® Code 87539 refers to the detection of the infectious agent HIV-2 through nucleic acid techniques, specifically focusing on quantification. This procedure involves the measurement of HIV-2 viral load in a patient's sample, which is crucial for monitoring the progression of the infection and the effectiveness of treatment. The process includes reverse transcription, which is a method used to convert RNA into DNA, allowing for the amplification and subsequent quantification of the viral genetic material. HIV-2 is one of the two main serotypes of the human immunodeficiency virus, the other being HIV-1. Both types can lead to acquired immunodeficiency syndrome (AIDS), a condition characterized by a severely weakened immune system. The transmission of HIV-2 can occur through various means, including sexual contact, unscreened blood transfusions, sharing of needles, and from mother to child during childbirth or breastfeeding. The detection of HIV-2 is essential for timely intervention and management of the infection, as it helps healthcare providers assess the viral load and adjust treatment plans accordingly. The procedure typically requires a blood sample, from which the nucleic acids are extracted and analyzed to determine the presence and quantity of HIV-2, thereby providing critical information for patient care.
