In simple words: This code is for a blood test that checks if you have antibodies to HIV (the virus that causes AIDS).A positive result means further tests are needed to confirm if you have HIV.

G0433 is an HCPCS code billing for infectious agent antibody detection using the enzyme-linked immunosorbent assay (ELISA) technique to screen for HIV-1 and/or HIV-2 antibodies.The test involves detecting antibodies produced by the body in response to HIV infection. A positive screening result necessitates confirmatory testing to confirm HIV infection.This code is specifically for screening purposes and does not encompass confirmatory testing.The test typically uses a blood sample, and the ELISA method involves detecting a biochemical color change indicating the presence of antibodies.

Example 1: A patient presents to their primary care physician expressing concerns about potential HIV exposure. The physician orders an HIV ELISA screening test (G0433) as part of a routine checkup. The test is performed at an outside laboratory., A pregnant woman undergoes routine prenatal testing, including an HIV screening test (G0433).The test is conducted at a CLIA-waived laboratory using a rapid test, requiring the QW modifier., An individual seeks testing at a community health clinic. The clinic uses a CLIA-waived ELISA HIV test (G0433), and the results are discussed with a counselor to support the patient in managing their healthcare.

Patient demographics, reason for ordering the test (risk factors, exposure history, pregnancy), date and time of specimen collection, test results, provider's interpretation and counseling provided, and CLIA waiver information if applicable.

** Always consult the most up-to-date payer guidelines for specific billing requirements, including coding, modifier application, and coverage policies.Confirm compliance with CLIA regulations.
