This is the Technical Appendix to the report detailing impacts of the Accountable Care Act (ACA) on costs and coverage for major sources of coverage without the Mandate to have coverage. We used the Health Benefits Simulation Model (HBSM), a micro-simulation model of the US health care system designed for simulating policies ranging from narrowly defined insurance market regulations to Medicaid coverage expansions and broad-based reforms involving multiple programs. In this document we explain how the model was used to simulate the impact of the ACA.  This includes the methods used to simulate the effect of the ACA without the mandate for people to have health insurance.
