Coverage Information & FAQs
- HMO (Health Maintenance Organization): Requires receiving care through the network of clinicians and facilities, often requiring primary doctor referrals to access specialist treatments.
- PPO (Preferred Provider Organization): Provides flexibility to visit out-of-network clinicians without requiring referrals, though seeking care with in-network providers offers lower out-of-pocket costs.
- EPO (Exclusive Provider Organization): Restricts coverage strictly to network providers except for emergency situations, but generally allows seeking treatment from network specialists without an official referral.
- POS (Point of Service): Bridges elements of HMO and PPO rules. It generally mandates an in-network primary care physician referral for specialized services but retains partial out-of-network lookup allowances at heightened cost tiers.
