AIDS or HIV-Positive Exemption. Enrollees with a confirmed diagnosis of AIDS, as indicated by an ICD-9-CM diagnosis code, or who are HIV-Positive and on anti retroviral drug treatment approved by the Federal Food and Drug Administration, are eligible for an exemption. The HMO must not counsel or otherwise influence an enrollee or potential enrollee in such a way as to encourage exemption from enrollment or continued enrollment. Exemption requests must come from the casehead or the enrollee and should be directed to the Department’s contracted Enrollment Specialist. Exemptions are processed as soon as possible and are effective on the first day of the month that anti retroviral treatment begins or the date that the enrollee was diagnosed with AIDS. Exemptions are not backdated more than nine months from the date the request is received.
