Coverage under prefix S4K

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.

EPO

This is an Exclusive Provider Organization (EPO) prefix. EPO plans do not cover out-of-network care except in genuine emergencies. Members can see any in-network specialist without a referral from their primary care physician. Claims for out-of-network non-emergency services will be denied.

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.
