UnitedHealthcare vs. Blue Cross Blue Shield (2026 Comparison)

UnitedHealthcare sells ACA plans in 27 states, limited to HMO and EPO options. BCBS covers 36 states and offers a broader range of plan types, including HMO, POS, EPO and PPO. Shoppers in states where both insurers operate can choose between the two, but BCBS is the only option in 16 states.

• HMO (Health Maintenance Organization): Requires you to select a primary care doctor who manages your treatment and issues referrals for specialist visits. Care is covered only within the plan's network, except in emergencies.
• POS (Point of Service): Combines elements of HMO and PPO plans. You'll need a primary care physician and referrals, but you can go outside the network for care at a higher out-of-pocket cost.
• EPO (Exclusive Provider Organization): Does not require referrals to see specialists and doesn't require a primary care physician. Coverage is limited to in-network providers unless it's an emergency.
• PPO (Preferred Provider Organization): Gives you the most flexibility. You can see specialists without referrals and receive care out of network, though out-of-network services cost more.
