How it works here
ACA Marketplace plans, explained for Arizona.
Arizona residents buy ACA Marketplace plans through HealthCare.gov. These are comprehensive plans that cover the ten essential health benefits, cannot deny you for a pre-existing condition, and are the only plans eligible for income-based premium tax credits.
Because Arizona runs a federal marketplace, you enroll at HealthCare.gov. Plans and prices are set at the county level across Arizona's 15 counties, so two neighbors in different counties can see different options.
Arizona expanded Medicaid, so if your income is low you may qualify for Medicaid instead of a subsidized plan — the Marketplace will tell you when you apply.
Arizona residents enroll through HealthCare.gov. The state expanded Medicaid (AHCCCS), so applications screen public coverage as well.
Maricopa and Pima counties usually offer more plan choice than many rural counties among Arizona's 15 counties.
A large snowbird and retiree population means working-age Marketplace shoppers often coordinate coverage decisions with Medicare-eligible household members.
