Coverage under prefix ATN

HMO

HMO (Health Maintenance Organization) plans require members to choose a primary care physician (PCP) and obtain referrals before seeing specialists. Out-of-network services are generally not covered except in emergencies. Claims must be submitted to the payer listed above and should include referral authorization when applicable.

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.

Medicare Advantage

Medicare Advantage (MA) coverage means this member receives their Medicare benefits through a private BCBS plan rather than through original Medicare. MA plans may have different payer IDs and claims addresses than the commercial plan. Check with the payer to confirm the correct submission details for Medicare Advantage claims.

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.
