CPT® Code 86762

The CPT® Code 86762 refers to the laboratory test for antibodies to rubella, a virus responsible for causing German measles. This test is particularly significant in the context of pregnancy, as a rubella infection during the first trimester can lead to serious fetal anomalies. The testing process involves analyzing a blood sample to determine the presence of specific antibodies that indicate either a current or past infection. The methodology commonly employed for this testing is chemiluminescent immunoassay, which is a sensitive and accurate technique for detecting these antibodies. There are two types of immunoglobulin tests performed: IgG and IgM. The IgG test is utilized to diagnose a past infection or to confirm immunity, while the IgM test is specifically aimed at identifying a current infection. It is important to note that if both IgG and IgM tests are conducted, each test must be reported separately to ensure accurate coding and billing for the services rendered.
