Coverage under prefix W3N

POS

This is a Point of Service (POS) prefix. POS plans offer flexibility similar to a PPO but incentivize in-network care through lower cost-sharing. Members designate a primary care physician who can issue referrals for the highest level of benefits. Out-of-network claims are covered but at significantly reduced rates.

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.

EPO

EPO coverage under this prefix means the member must use network providers but does not need referrals for specialist visits. This plan type is becoming more common as it offers lower premiums than PPO plans while providing more flexibility than HMOs. Verify network status before providing services.
