CPT® Code 86694

The CPT® Code 86694 refers to a non-specific type test for antibodies against the herpes simplex virus (HSV). This test is performed on a sample of blood or cerebrospinal fluid to detect the presence of antibodies that indicate exposure to the virus. Herpes simplex virus is primarily transmitted through direct contact, and the initial infection often manifests as ulcerations on the skin or mucous membranes. After the primary infection, the virus can enter a latent phase, remaining dormant in the body and potentially reactivating due to various triggers such as other illnesses, infections, or stress. Certain populations, including neonates and individuals with compromised immune systems, are particularly vulnerable to severe complications, including ocular or central nervous system infections. Various testing methodologies exist for diagnosing HSV infections, including indirect hemagglutination (IHA), chemiluminescent immunoassay, and enzyme-linked immunosorbent assay (ELISA). The test typically involves measuring immunoglobulin G (IgG) and immunoglobulin M (IgM) levels to confirm the presence of HSV. It is important to note that if both IgG and IgM tests are conducted, each test should be reported separately. The code 86694 is specifically designated for non-specific type HSV testing, while codes 86695 and 86696 are used for tests that identify specific types of HSV, namely type 1 and type 2, respectively. Additionally, these codes can also be utilized to report the presence of glycoprotein G-specific antibodies for HSV type 1 and/or type 2.
