Coverage under prefix NXN

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.

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.

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.
