Many consumers are ill-informed about Medicare and Medicaid’s role in long-term care, and greater planning could help reduce the danger of soaring Medicaid costs, according to a new report from America’s Health Insurance Plans.

Over the next 20 years, federal and state governments are expected to spend $3.7 trillion on long-term care expenses, the report said. Between 2008 and 2027, annual Medicaid long-term care expenditures are projected to grow by 124% from $51.5 billion to $115.6 billion. AHIP represents most of the nation’s commercial insurers. Researchers at Strategic Affairs Forecasting and Paul A. London Associates conducted the report.

Too many people believe that Medicare will help pay for long-term care expenses, when actually it will provide only a limited amount of rehabilitative care, according to report authors. Up to two-thirds underestimate their potential need for long-term care, they note.
