Coverage under prefix E4Q

PPO

This prefix is associated with a PPO plan. Preferred Provider Organization coverage gives members flexibility to see specialists without referrals and to use out-of-network providers at higher cost-sharing. Claims can be submitted for both in-network and out-of-network services, though reimbursement rates differ.

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.

HDHP

This prefix is associated with a High-Deductible Health Plan. HDHP members pay more out-of-pocket before insurance coverage begins. These plans are commonly paired with HSA or HRA accounts. When billing, be aware that the member may have significant cost-sharing responsibility until their annual deductible is satisfied.
