Coverage under prefix K4A

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.

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.

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.
