SCAN Health Plan, Wellpoint and Humana are the best Medicare Advantage providers in Arizona for 2026. SCAN leads HMO plans, Wellpoint leads HMO-POS plans and Humana leads PPO plans, each offering the strongest combination of cost and quality in its category.
The plan type determines more about your coverage than the insurer does. An HMO restricts care to a provider network and requires a referral (written approval from your primary care doctor before each specialist visit). A PPO covers any Medicare-approved provider without a referral at higher average cost. An HMO-POS plan adds occasional out-of-network access to the HMO structure.
