CPT® Code 86063

The CPT® Code 86063 refers to the screening for antistreptolysin O (ASO) antibodies in a blood sample. This procedure is essential for detecting the presence of ASO antibodies, which are produced in response to infection by Group A Streptococcus bacteria. The presence of these antibodies can be indicative of various medical conditions, including active streptococcal infections, bacterial endocarditis, post-streptococcal glomerulonephritis, rheumatic fever, and scarlet fever. The ASO screening can be performed using different laboratory methods, such as nephelometry and latex immunoturbidimetry, which help in determining the concentration of these antibodies in the blood. While the ASO titer, represented by CPT® Code 86060, provides a quantitative measurement expressed in Todd units per milliliter, CPT® Code 86063 focuses solely on the qualitative aspect, indicating whether ASO antibodies are present or absent in the sample. This distinction is crucial for healthcare professionals in diagnosing and managing streptococcal-related conditions.
