CPT® Code 87902

The CPT® Code 87902 refers to the process of conducting an infectious agent genotype analysis specifically for the Hepatitis C virus (HCV) through nucleic acid testing, which can involve either DNA or RNA. This analysis is crucial for understanding the genetic makeup of the virus, which is essential for tailoring effective treatment strategies. Hepatitis C is a viral infection that primarily affects the liver, leading to acute inflammation that can progress to chronic conditions, including liver dysfunction, cirrhosis, and even hepatocellular carcinoma (liver cancer). The Hepatitis C virus is categorized into six major genotypes, each with numerous subtypes, which exhibit varying responses to antiviral therapies. Notably, genotype 1 is prevalent in approximately 70 percent of cases in the United States and is associated with a less favorable response to treatment, as well as a higher risk of developing liver cancer. The genotyping process is intricate and involves analyzing a blood sample to identify specific nucleic acid sequences associated with HCV. This is achieved through a series of steps: initially, specific nucleic acid sequences are amplified using techniques such as polymerase chain reaction (PCR); subsequently, the amplified products undergo purification and further molecular analysis; finally, the resulting sequences are compared against known sequences to accurately identify the HCV genotype. This detailed analysis is vital for clinicians to devise the most effective and personalized treatment plans for patients infected with Hepatitis C.
