What is iLOS?

iLOS (In Lieu of Services) is a multi-year initiative by the Oregon Health Authority (OHA) to improve the quality of life and health outcomes of Medicaid members through broad delivery system, program and payment reform across the Medicaid program.

This resource page has been developed to provide tools and resources to help providers easily navigate the iLOS program so they can better serve our members. On this page you will find the most current information – guides, forms, trainings and more – as well as the latest updates from our Plan. This page will be updated as new information and guidelines are available.
