CPT® Code 86756

The CPT® Code 86756 refers to a laboratory test specifically designed to measure antibodies against the respiratory syncytial virus (RSV). RSV is a common virus that primarily affects the respiratory system and is known to circulate in the United States predominantly from late fall through spring. The illness caused by RSV is characterized by symptoms such as a runny nose, nasal congestion, and a persistent cough. While RSV can lead to mild respiratory symptoms in healthy individuals, it can be particularly severe in infants, potentially resulting in serious conditions such as bronchitis and pneumonia. The presence of IgG and IgM antibodies in the blood, as indicated by a positive antibody titer, can suggest either a current or past infection with RSV. To perform this test, a blood sample is collected through a procedure known as venipuncture, which is reported separately. The serum obtained from the blood sample is then analyzed using a technique called immunofluorescence, which allows for the detection of RSV antibodies in the serum.
