Coverage under prefix ZKU

HMO

This is a Health Maintenance Organization (HMO) prefix. HMO plans have stricter routing requirements than PPO plans. Members select a PCP who manages their care and issues referrals. Claims for specialist services should include the referral number. Out-of-network claims will typically be denied unless emergency criteria are met.

POS

Under this POS prefix, the member can access care both in-network and out-of-network, with cost-sharing that varies based on how the care is accessed. In-network care coordinated through the member's PCP has the lowest out-of-pocket cost. Include referral documentation when billing at the in-network benefit level.

Medicare Advantage

Medicare Advantage coverage under this prefix means the plan administers Medicare Part A and Part B benefits on behalf of CMS. These claims may have different processing rules than commercial claims, including different prior authorization requirements and appeal timelines. CMS timely filing rules (365 days) typically apply.
