HRAs have become popular in recent years, thanks in part to the freedom and control that they offer employers. But what does HRA mean? More specifically, what is an HRA plan? An HRA is a Health Reimbursement Arrangement or a type of health plan that allows employers to reimburse employees for healthcare-related expenses. While traditional group health plans leave little room for customization, HRAs help give some of that power back to employers and employees so that they can work towards solutions on a more individual level.
