CPT® Code 87520

The CPT® Code 87520 refers to the detection of the hepatitis C virus (HCV) through nucleic acid testing, specifically utilizing a direct probe technique. Hepatitis C is a viral infection that primarily affects the liver, leading to inflammation and potentially resulting in chronic conditions such as cirrhosis and liver cancer. The detection of HCV's nucleic acid, either DNA or RNA, is crucial for determining the presence of an ongoing or chronic infection in patients. This method is particularly effective in identifying low levels of the virus, which may not be detectable through other means. The direct probe technique involves the use of laboratory-prepared complementary strands of nucleic acid that are designed to bind specifically to the target nucleic acid of the virus. These probes are often labeled with chemical fluorescence, allowing for the formation of stable, double-stranded complexes that can be identified within the sample. This process is essential for accurate diagnosis and management of hepatitis C, as it provides vital information regarding the presence of the virus in the patient's system.
