Coverage under prefix CNL

HMO

Under this HMO prefix, the member's coverage is limited to the plan's provider network. Care is coordinated through a primary care physician. Specialist visits require a referral from the PCP. When billing, confirm that the referring provider and the referral authorization number are included on the claim.

PPO

PPO (Preferred Provider Organization) plans allow members to visit any healthcare provider without a referral. In-network providers cost less, but out-of-network care is still covered at a reduced rate. When billing for a PPO plan, submit claims directly to the payer listed above. No referral documentation is needed.

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.

EPO

Under this EPO prefix, the member has no out-of-network coverage for routine care. However, unlike HMO plans, no referral is needed to see a specialist within the network. When billing, confirm the provider's network participation status with the plan before submitting the claim.
