Coverage under prefix AHZ

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.

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.

Medicare Advantage

Under this prefix, the member may have Medicare Advantage coverage administered by this BCBS plan. MA claims are subject to CMS regulations in addition to the plan's own policies. Balance billing restrictions apply. Verify the member's specific MA plan details and confirm the correct payer ID for electronic submission.
