HIV: confirmed cases and code B20

Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.

Guidelines I.C.1.a.1; I.C.1.a.2.a

“Code only confirmed cases of HIV infection/illness.”

“the provider's diagnostic statement that the patient is HIV positive or has an HIV-related illness is sufficient.”

“If the term "AIDS" or "HIV disease" is documented or if the patient is treated for any HIV-related illness or is described as having any condition(s) resulting from the patient's HIV positive status; code B20, Human immunodeficiency virus [HIV] disease, should be assigned.”
