CPT® Code 87912

The CPT® Code 87912 refers to the process of conducting an infectious agent genotype analysis specifically for the Hepatitis B virus (HBV) through nucleic acid testing, which can involve either DNA or RNA. This procedure is crucial for patients who have tested positive for HBV, a viral infection known for its potential to cause significant liver damage and increase the risk of liver cancer. The genotyping process involves amplifying and increasing the targeted DNA, which allows for the precise detection of the specific genotype of the virus. Understanding the genotype of HBV is essential as it can provide valuable prognostic information regarding the disease's progression and assist healthcare providers in determining the most appropriate antiviral treatment options for the patient. The analysis is performed on a blood sample, which is obtained through a separately reportable venipuncture. The serum or plasma from the blood sample is then subjected to testing methods such as polymerase chain reaction (PCR) or sequencing to accurately identify the HBV genotype.
