Advances in biomedical research have resulted in new standards for HIV treatment that involve earlier intervention with more complex combination antiretroviral therapy. This article examines the implications of these treatments for federally funded programs that provide HIV care and discusses mechanisms for making Medicaid and the AIDS Drug Assistance Program (ADAP) consistent with the treatment standards. The article provides a rationale for expanding access by expanding entitlement programs (Medicaid) rather than discretionary programs (ADAP). A potential legislative approach to Medicaid expansion is described. Cost projections suggest that this approach is feasible and would constitute a significant step toward increasing access to HIV care.
