Question:
What codes are used to report infectious antigen detection?
Answer:
CPT code series 87260–87999 includes method-specific codes to report testing for specific infectious agent antigens. CPT cannot list every infectious organism, and, for this reason, this code series also includes method-specific codes for the testing of organisms that are not otherwise defined in CPT. Two examples of these codes are 87797 and 87798, which are used to report direct and amplified probe techniques. Methods of testing described in this code series include immunoflourescent, EIA, and nucleic acid direct and amplified probe methods.
