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