Research spotlight: Medicare spending on clinical care for people aging with HIV projected to rise steeply over next decade

As more Americans with HIV age into Medicare eligibility, costs are expected to increase substantially. The study projects nearly 200,000 beneficiaries by 2035 and $27.3 billion in annual spending. Policy changes like the Inflation Reduction Act could save billions, while generic HIV medications may further reduce costs.
