CPT Code 87425 | Description & Clinical Information

CPT 87425 describes the utilization of an immunoassay technique, such as EIA, by a lab analyst to perform a test that detects antigens of rotavirus.

Official Description

The CPT book defines CPT code 87425 as: “Infectious agent antigen detection by immunoassay technique (eg, enzyme immunoassay [EIA], enzyme-linked immunosorbent assay [ELISA], fluorescence immunoassay [FIA], immunochemiluminometric assay [IMCA]), qualitative or semiquantitative; rotavirus”.

Clinical Information

The procedure describes by CPT code 87425 involves the use of an immunoassay technique to detect the presence of rotavirus antigens in a primary source specimen obtained from the patient. The primary source specimen, also known as a fecal specimen, is collected and sent to the laboratory for further testing.

Once the fecal specimen is received in the laboratory, a lab analyst performs all the technical steps required to assess the presence of rotavirus antigens. The possible methods used for the analysis include the enzyme immunoassay (EIA), enzymelinked immunosorbent assay (ELISA), fluorescence immunoassay (FIA), or immunochemiluminometric assay (IMCA).

Although the test is not limited to specific conditions, clinicians may order the test to diagnose or rule out possible infection with rotavirus, a virus that causes inflammation of the digestive tract, especially in young children or patients with a weakened immune system. People infected with rotavirus are likely to experience symptoms such as vomiting, diarrhea, and dehydration.

The CPT 87425 procedure is a critical diagnostic test as rotavirus infection can lead to serious complications such as electrolyte imbalances, severe dehydration, and even death. Children under the age of five are more susceptible to rotavirus infection, with nearly every child being infected at least once by the age of five.

Rotavirus infection is highly contagious and is transmitted through contact with the infected fecal matter. The virus can survive on surfaces for a long time and can be easily transmitted from person to person. Therefore, it is essential to diagnose and treat rotavirus infection using CPT code 87425 as early as possible.

In conclusion, the CPT 87425 procedure is a valuable diagnostic tool that helps clinicians detect and diagnose rotavirus infection. The detection of rotavirus antigens in fecal specimens using this technique is vital in diagnosing and treating this highly contagious and potentially fatal virus. Prompt diagnosis and appropriate treatment can help reduce the risk of complications and improve patient outcomes.
