  • Approved Changes in Indiana’s Section 1115 Medicaid Waiver Extension

    Issue Brief

    On February 1, 2018, the Centers for Medicare and Medicaid Services (CMS) approved an amended extension of Indiana’s Healthy Indiana Program 2.0 (HIP 2.0) Section 1115 demonstration waiver. Indiana’s waiver initially implemented the ACA’s Medicaid expansion from February, 2015 through January, 2018 by modifying Indiana’s pre-ACA limited coverage expansion waiver (HIP 1.0). Unlike other states that implemented the ACA’s Medicaid expansion through a waiver, Indiana’s demonstration also changes the terms of coverage for non-expansion adults (low-income parents and those eligible for Transitional Medical Assistance, TMA). The February, 2018 extension continues most components of HIP 2.0 and adds some new provisions.
