Coverage under prefix IEI

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.

Traditional Indemnity

This is a traditional indemnity prefix. Unlike managed care plans (HMO, PPO, EPO), indemnity plans do not use provider networks. There are no referral requirements and no restrictions on which providers the member can see. Submit claims to the payer listed above for reimbursement at the plan's allowed rate.

Medicare Advantage

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.
