Coverage under prefix GNB

HMO

This is a Health Maintenance Organization (HMO) prefix. HMO plans have stricter routing requirements than PPO plans. Members select a PCP who manages their care and issues referrals. Claims for specialist services should include the referral number. Out-of-network claims will typically be denied unless emergency criteria are met.

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.
