2025 CPT code 87467

Quantitative detection of hepatitis B surface antigen (HBsAg) using immunoassay techniques.

For multiple specimens/sites, use modifier 59. For repeat laboratory tests performed on the same day, use modifier 91.

Modifiers 59 and 91 are applicable as described in the coding guidelines.

Medical necessity is determined by the patient's clinical condition and the need to monitor the progression of hepatitis B or the effectiveness of antiviral treatment.

The lab analyst performs the test using methods like chemiluminescence immunoassay to measure HBsAg levels in a serum specimen. This involves binding the antigen to an antibody, labeling the complex, and measuring light emissions corresponding to the antigen quantity.

IMPORTANT For qualitative HBsAg testing, use 87340 or 87341. Prior to the addition of this code, 82397 may have been used.

In simple words: This test measures the amount of hepatitis B surface antigen (HBsAg) in your blood.It's used to track chronic hepatitis B infections and how well antiviral treatments are working.

Infectious agent antigen detection by immunoassay technique (e.g., enzyme immunoassay [EIA], enzyme-linked immunosorbent assay [ELISA], fluorescence immunoassay [FIA], immunochemiluminometric assay [IMCA]), qualitative or semiquantitative; hepatitis B surface antigen (HBsAg), quantitative.(For qualitative hepatitis B surface antigen [HBsAg], use 87340)

Example 1: A patient with a known hepatitis B infection needs regular monitoring to determine if the infection has become chronic., A patient undergoing antiviral therapy for chronic hepatitis B requires monitoring to assess treatment response., A patient presents with symptoms suggestive of hepatitis B and requires quantitative HBsAg testing to confirm and assess the infection.

Documentation should include the reason for the test, the patient's medical history related to hepatitis B, and any relevant clinical findings.
