Coverage under prefix K5T

POS

POS coverage under this prefix operates on a tiered system. Tier 1 (in-network with referral) provides the highest coverage. Tier 2 (in-network without referral) provides moderate coverage. Tier 3 (out-of-network) provides the lowest coverage. Verify which tier applies before submitting the claim.

EPO

This prefix is associated with an EPO plan. Exclusive Provider Organization coverage combines elements of HMO and PPO plans: members must stay in-network like an HMO, but can self-refer to specialists like a PPO. Out-of-network services are not covered except for emergencies.

Medicaid

Under this prefix, the member may have Medicaid coverage managed by this BCBS plan. Medicaid claims have specific rules around cost-sharing, balance billing, and timely filing that override the plan's standard commercial policies. Contact the plan's Medicaid provider services line for submission details.
