Coverage under prefix IMU

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.

Medicaid

This prefix is associated with Medicaid managed care. When a BCBS plan administers Medicaid, the claims process may differ from commercial coverage: different payer ID, different claims address, different prior authorization rules, and different timely filing limits. Always verify Medicaid-specific details before submitting.

EPO

This is an Exclusive Provider Organization (EPO) prefix. EPO plans do not cover out-of-network care except in genuine emergencies. Members can see any in-network specialist without a referral from their primary care physician. Claims for out-of-network non-emergency services will be denied.
