This Policy Insight explores possible explanations for the continued rise in Medicare Advantage enrollment between 2010 and 2013 in spite of a projected decrease following payment changes in the Affordable Care Act (ACA).
This Data Spotlight provides an overview of Medicare Advantage enrollment patterns in March 2013, and examines variations by plan type, state, and firm. It also analyzes trends in premiums paid by beneficiaries enrolled in Medicare Advantage plans, including variations by plan type, and describes the out-of-pocket limits and prescription drug coverage in the Part D “donut hole” provided by the plans in 2013.
The Affordable Care Act (ACA) will significantly increase coverage options through an expansion of Medicaid and the creation of new health insurance exchange marketplaces. However, effective outreach and enrollment efforts will be key to ensuring that new coverage opportunities translate into increased coverage.
This brief provides insight into lessons learned from Medicaid and CHIP outreach and enrollment strategies by profiling a successful initiative of the Michigan Primary Care Association to facilitate coverage renewals through a systematic, technology-based reminder system coupled with one-on-one assistance.
