Coverage under prefix KNW

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.

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.

HDHP

This prefix is associated with a High-Deductible Health Plan. HDHP members pay more out-of-pocket before insurance coverage begins. These plans are commonly paired with HSA or HRA accounts. When billing, be aware that the member may have significant cost-sharing responsibility until their annual deductible is satisfied.
