Coverage under prefix M3B

EPO

Under this EPO prefix, the member has no out-of-network coverage for routine care. However, unlike HMO plans, no referral is needed to see a specialist within the network. When billing, confirm the provider's network participation status with the plan before submitting the claim.

Medicaid

This prefix includes Medicaid managed care coverage. The BCBS plan administers Medicaid benefits on behalf of the state. Claims submission, prior authorization, and reimbursement rules may follow state Medicaid guidelines rather than the plan's standard commercial policies. Confirm the correct payer ID for Medicaid claims.

POS

POS (Point of Service) plans combine features of HMO and PPO coverage. Members choose a primary care physician and can get referrals to see in-network specialists at lower cost, or self-refer to out-of-network providers at higher cost. Claims should include referral information when the member uses the in-network benefit level.
