Coverage under prefix IIK

Medicaid

This prefix is associated with Medicaid managed care. When a BCBS plan administers Medicaid, the claims process may differ from commercial coverage: different payer ID, different claims address, different prior authorization rules, and different timely filing limits. Always verify Medicaid-specific details before submitting.

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

This prefix includes Medicare Advantage coverage. MA plans follow CMS guidelines for timely filing (365 days from date of service), which may differ from the commercial plan's deadline. The payer ID for Medicare Advantage claims may differ from the standard commercial payer ID. Verify before submitting.
