For most retirees, Medicare is the best health insurance available, and you qualify at 65. Sign up starting three months before your birthday month. Missing that window without other qualifying coverage results in a permanently higher Part B premium, which is $202.90 monthly in 2026 per CMS.
Original Medicare pays most covered medical costs but leaves you responsible for a portion of every service. A Medicare Supplement plan, also called Medigap, covers most of that remaining portion through a private insurer.
But Medicare isn't available until 65. The ACA Marketplace is the most practical alternative for early retirees, with premium tax credits reducing monthly costs based on your household income. Silver plans are the practical starting point because they're the only ACA tier that qualifies for cost-sharing reductions, which lower your deductible and copays beyond what premium credits alone accomplish.
