Description: This report provides a comprehensive overview of the HIV-positive population enrolled in Medicare, with an emphasis on demographic trends, healthcare utilization, and cost patterns. It aims to better understand how this population is aging into Medicare and how their needs may differ from the broader Medicare population. The study compares HIV-positive and non-HIV-positive members across medical and pharmacy services to identify potential gaps in care and inform program design. It also highlights key considerations for policymakers, actuaries, and healthcare providers managing this unique population. By presenting data-driven insights, the report serves as a foundation for future research and policy development to ensure equitable, effective care for HIV-positive Medicare beneficiaries.
