Medicaid and Health Insurance Exchanges 
Comparing Benefits and Costs

The Patient Protection and Affordable Care Act (ACA) expands health insurance coverage primarily through two mechanisms: by expanding the existing Medicaid program and by establishing new health insurance exchanges where certain individuals and businesses can purchase private health insurance. Under ACA, Medicaid and exchanges are envisioned to work in tandem, with the potential to provide a continuous source of subsidized coverage for lower-income individuals and families, beginning in 2014. This book provides an analysis of some of the key similarities and differences between Medicaid and insurance plan structure in plans offered through exchanges. Because Medicaid services vary by population covered and by state, and exchange plans can also vary by state, this book provides insight into the complexities and issues when comparing beneficiary benefits and costs to individuals for Medicaid and the exchanges. The inherent variations in Medicaid and the uncertainty about exactly how the exchanges will operate are just two of the factors that complicate this comparison.
