John Galvin, 64, of North Kingstown, Rhode Island, is delaying a colonoscopy until he turns 65 and qualifies for Medicare. His monthly Obamacare premium tripled to $2,460, with a $2,700 deductible making the test financially unfeasible. His wife Nancy is similarly postponing a CT scan.

The expiration of enhanced federal subsidies at year-end hit those earning above 400% of the federal poverty level-$86,560 for a two-person household. Adults aged 50-64, who made up half of ACA enrollees, now face steep rate hikes. In some states, premiums more than tripled.

Health experts warn that delaying care increases long-term costs and risks. Patient advocates say this creates a surge in unmet medical needs, forcing Medicare to absorb higher future expenses.

Marci Heinbaugh, 63, in rural Illinois, saw her plan’s premium double from $1,100 to $2,333, with an $10,150 out-of-pocket maximum. She’s considering dropping coverage altogether.

A 2024 AARP survey found 1 in 5 adults over 50 have no retirement savings. Many are using retirement funds to cover premiums-Galvin expects to spend $30,000 to maintain his current plan.

"It’s forcing people to make impossible choices," said Natalie Kean, Justice in Aging. "The short-term savings may become long-term liabilities for individuals and taxpayers."

Medicare Part B premiums rose to $203/month in January, further straining budgets.
