Had an Aetna CVS Health plan?
Aetna left Covered California for the 2026 plan year, and its former regions include Alameda County. If you were enrolled with Aetna, you should have been moved or asked to pick a new plan – it is worth a quick review to make sure your doctors are in your new network. Book a free review or call (855) 847-7020.
Final availability depends on your exact ZIP code – carriers draw their own service maps inside a county. We check your address against every carrier’s current filing before quoting.
