The age gap between 50 and 64 is costing millions of Americans their health, with roughly 8 million Americans aged 50 to 64 carrying more medical debt than any other age group in America. This gap widens every year as chronic conditions increase, and insurance premiums rise. Federal subsidies that helped keep insurance premiums affordable for this group expired at the end of 2025, with no renewal in sight. The AARP Public Policy Institute report found that 8 million adults ages 50 to64 had medical debt in 2023, the highest prevalence of any age group. Most of these adults have health insurance through an employer or individual market, but still cannot keep up with costs. Expiring ACA premium tax credits could push nearly 5 million midlife adults off their coverage. An AARP-commissioned analysis by Avalere Health predicts that 4.8 million adults aged 50-64 will face higher premiums for marketplace health insurance in 2026, representing 92% of the 5.2 million expected to enroll in marketplace coverage this year. Under ACA rules, insurers can charge people in their 50s and 60s up to three times more than younger adults purchasing the same plan.
