HIV disease is coded under B20 (Human immunodeficiency virus disease) when symptomatic or AIDS-defining conditions are documented. Z21 is asymptomatic HIV infection. R75 is inconclusive HIV serology. Once a patient is coded B20, that classification persists on subsequent encounters even after the patient is asymptomatic.
