Our take
'Best health insurance' depends almost entirely on three things: your local provider network, your specific prescriptions, and your expected medical year. A plan that's perfect for one person can be inadequate for another in the same city.
We weighted four factors: network quality (30%), plan design (25%), cost relative to peer plans (25%), and customer experience (20%). For Medicare Advantage, we incorporate CMS star ratings; for ACA marketplace plans, NCQA accreditation data.

Frequently asked questions
When can I buy health insurance?
Open enrollment runs November-January for marketplace plans. Outside that window you need a qualifying life event.
HMO or PPO?
HMOs are cheaper but require referrals and network providers. PPOs cost more but offer flexibility.
How do ACA subsidies work?
Subsidies cap your premium at a percentage of income up to 400% of the federal poverty line (extended through 2025).
What's a qualifying life event?
Marriage, divorce, having a baby, adopting, losing other coverage, moving to a new coverage area, or income changes that affect subsidy eligibility. You get a 60-day Special Enrollment Period from the date of the event. COBRA expiring counts; voluntarily dropping coverage doesn't.
Bronze, Silver, Gold, or Platinum — which tier?
Bronze: lowest premium, highest out-of-pocket. Silver: middle ground and the only tier where cost-sharing reductions apply (if you qualify by income). Gold: higher premium, lower out-of-pocket — math favors this if you use a lot of care. Platinum: rarely the right answer unless you have a chronic condition with predictable high spend.
What's an HSA and is it worth it?
A Health Savings Account is a triple-tax-advantaged investment account paired with an HSA-qualifying high-deductible plan. Contributions are pre-tax, growth is tax-free, and withdrawals for medical expenses are tax-free. If you can max it out and pay current medical expenses out of pocket, it's the best retirement account most people don't know about.
