Coverage under prefix GAH

HMO

This prefix is linked to an HMO plan. Health Maintenance Organization coverage requires members to use in-network providers and coordinate care through a designated primary care physician. Referrals are typically required for specialist visits. Claims submitted without proper referral documentation may be denied.

EPO

This prefix is associated with an EPO plan. Exclusive Provider Organization coverage combines elements of HMO and PPO plans: members must stay in-network like an HMO, but can self-refer to specialists like a PPO. Out-of-network services are not covered except for emergencies.

PPO

PPO coverage under this prefix means the member can access any provider. In-network providers have negotiated rates with the plan, while out-of-network providers are reimbursed based on usual and customary charges. Prior authorization is generally not required for routine services but may be needed for high-cost procedures.
