Health Insurance Exchanges (HIX) 2.0

Data to Measure Each State's Key Implementation Decisions

RWJF-VoteVax-b-8422_RET

HIX 2.0 provides information on the variation in implementation of the Affordable Care Act across all 50 states and tracks each state’s key implementation decisions.

 

Issue Briefs:

HIX 2.0 issue briefs provide insight into what health insurance exchange features are most effective and what factors explain state variation.

Datasets:

These data were collected from primary sources such as statutes and other regulatory decisions, but also from official gubernatorial press releases and other reliable news sources to ensure that the quickly changing nature of exchange implementation is being addressed. Datasets will be posted regularly on this site as they are completed, and completed datasets will be updated, and in some cases combined, as implementation moves forward. The date the datasets were last updated will be specified on each dataset's webpage.

  • SHOP Participation Rules: Characteristics of each state’s small business health insurance exchange and how participation rules on the small business exchanges vary between states, as well as their relationship to the individual exchanges.
