Indiana initially implemented the ACA’s Medicaid expansion through a Section 1115 waiver in February 2015. Indiana’s waiver included important changes from federal law regarding enrollment and premiums. The initial waiver expired, and Indiana received approval for a waiver extension in February, 2018 which continues most components of HIP 2.0 and adds some new provisions related to enrollment and premiums. This brief looks at available data from the state’s evaluation of premiums prepared by The Lewin Group (as well as other reporting to CMS) to highlight what is known about the impact of these policies to date. We review these data to identify potential implications for changes in the recent Indiana renewal and for other states considering similar provisions.
