No. ACA plans vary by state and even by county. While all Marketplace plans must follow the same federal rules and cover essential health benefits, each state has different insurers, plan options, and pricing.
Do I have to cancel my old insurance before enrolling in a new ACA plan?
Usually no—if you switch plans on the Marketplace, your new plan will replace the old one on your new coverage start date. If you’re coming from non-Marketplace coverage (employer, off-exchange, Medicaid/Medicare), cancel that only after your new ACA plan’s start date is confirmed to avoid gaps or double premiums.
