Coverage under prefix A9L

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.

Traditional Indemnity

This is a traditional indemnity prefix. Unlike managed care plans (HMO, PPO, EPO), indemnity plans do not use provider networks. There are no referral requirements and no restrictions on which providers the member can see. Submit claims to the payer listed above for reimbursement at the plan's allowed rate.

HMO

This prefix is linked to an HMO plan. Health Maintenance Organization coverage requires members to use in-network providers and coordinate care through a designated primary care physician. Referrals are typically required for specialist visits. Claims submitted without proper referral documentation may be denied.
