Health insurance exchanges under the Patient Protection and Affordable Care Act: regulatory and design challenges.

Under the Patient Protection and Affordable Care Act, all states are required to establish health insurance exchanges, marketplaces where individuals and small businesses can purchase health care coverage. In establishing these exchanges, states must address a range of regulatory and design issues to ensure that their exchanges are sustainable and meet the needs of their populations. The issues include the degree of federal involvement in the management of the exchanges, the overall structure and governance of the exchanges, the requirements for insurance plans to be offered on the exchanges, and the design of the exchanges themselves. Each of these issues will play a crucial role in determining the quality of coverage offered to consumers and how effectively they can access that coverage.
