Coverage under prefix ZIZ

PPO

Under this PPO prefix, members are covered for both in-network and out-of-network care. The plan pays a higher percentage of allowed charges when members use participating providers. No gatekeeper or primary care referral is required. Verify the member's specific benefits for cost-sharing details.

Medicaid

Medicaid managed care under this BCBS prefix means the state has contracted with this plan to administer Medicaid benefits. Balance billing Medicaid members is prohibited. Timely filing requirements may follow state Medicaid rules rather than the plan's commercial deadlines. Contact the plan to confirm submission requirements.

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.
