Older Adults Too Young for Medicare Face Rising Health Insurance Costs

For millions of Americans aged 55 to 64, accessing affordable health insurance remains a significant challenge. Though not yet eligible for Medicare, many in this age group face heightened medical needs and correspondingly high premiums in the private insurance market. As federal subsidies tied to the Affordable Care Act (ACA) remain temporary and state-level Medicaid expansion varies, this demographic often falls into a coverage gap where care is needed but financially out of reach.

Who Is Affected and Why?

Adults between the ages of 55 and 64 are more likely to develop chronic conditions such as hypertension, diabetes, and heart disease. According to the Kaiser Family Foundation, nearly half of individuals in this age bracket have at least one chronic condition requiring ongoing care. Despite these risks, they are ineligible for Medicare, which begins at age 65, and may earn too much to qualify for Medicaid in states that have not expanded eligibility under the ACA.

In non-expansion states, adults earning above the federal poverty level but below 400% of it may still struggle to afford marketplace plans without sufficient subsidies. Even with premium tax credits, out-of-pocket costs including deductibles and copays can deter individuals from seeking necessary care.

The Impact of Expired Federal Subsidies

The American Rescue Plan Act (ARPA) of 2021 temporarily enhanced ACA subsidies, lowering premiums for millions of enrollees. These expansions were extended through the Inflation Reduction Act of 2022, but are set to expire at the complete of 2025 unless Congress acts to renew them.

According to the Congressional Budget Office (CBO), if these enhanced subsidies lapse, an estimated 3 million people could lose coverage, with premiums increasing by an average of 50% for marketplace enrollees. For older adults, whose base premiums are already higher due to age-based rating, this could mean monthly costs exceeding $800 for a silver plan in some regions.

State-Level Variations in Coverage

Access to affordable coverage varies significantly by state. In the 10 states that have not adopted Medicaid expansion, adults earning between 100% and 138% of the federal poverty level fall into a “coverage gap” — earning too little to qualify for marketplace subsidies but too much for traditional Medicaid.

For example, in Texas, Florida, and Georgia — three of the largest non-expansion states — KFF estimates that over 2 million low-income adults are left without viable insurance options. Many in this group are aged 50 to 64, facing both financial strain and delayed care due to cost concerns.

Conversely, in expansion states, low-income adults in this age bracket are more likely to qualify for Medicaid, which offers comprehensive benefits with minimal or no premiums. Studies from the Health Affairs journal present that Medicaid expansion is associated with improved access to care, better chronic disease management, and reduced mortality among adults aged 55 to 64.

What Can Be Done?

Policy solutions to address this issue include:

• Making enhanced ACA subsidies permanent: Extending the Inflation Reduction Act’s subsidy expansions beyond 2025 would prevent premium spikes and maintain access for millions.
• Closing the Medicaid coverage gap: Federal legislation could offer a fallback option for low-income adults in non-expansion states, similar to proposals considered during recent budget negotiations.
• Allowing Medicare buy-in for ages 50–64: Some lawmakers have proposed permitting older adults to purchase into Medicare early, potentially offering a more affordable alternative to private plans.
• Strengthening state-based reinsurance programs: States like Minnesota and Wisconsin have used reinsurance to stabilize individual markets and lower premiums, particularly for older enrollees.

Key Takeaways

• Adults aged 55 to 64 often face high health insurance costs due to increased medical needs and age-based pricing, despite being ineligible for Medicare.
• Temporary federal subsidies under the ACA have helped lower premiums, but are set to expire in 2025 unless renewed by Congress.
• In states that have not expanded Medicaid, low-income adults in this age group may fall into a coverage gap with no affordable options.
• Policy actions such as making subsidies permanent, expanding Medicaid, or enabling a Medicare buy-in could significantly improve affordability, and access.

Looking Ahead

As the 2025 deadline for enhanced ACA subsidies approaches, the affordability of health insurance for older adults remains a pressing public health issue. Without congressional action, millions risk losing coverage or facing unsustainable costs. Addressing this gap requires sustained policy attention — one that recognizes the unique needs of Americans who are too young for Medicare but increasingly in necessitate of reliable, affordable care.
