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.
Medicaid coverage under this prefix means the member's Medicaid benefits are administered by a BCBS managed care plan. Medicaid managed care claims may have different submission requirements, payer IDs, and timely filing deadlines than commercial claims. Verify the specific Medicaid plan details with the payer.
Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.
