Coverage under prefix IWN

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.

POS

This prefix is linked to a POS plan. Point of Service coverage gives members a choice at the time of service: use the HMO-style in-network benefit with a referral for lower costs, or access out-of-network providers at reduced coverage levels. The billing approach depends on which option the member chooses.
