The Center for Consumer Information and Insurance Oversight (CCIIO)

"The Affordable Care Act provides consumers with significant new protections, including the ability to appeal decisions by plans to deny coverage of needed services and select an available primary care provider of their choosing.

"As part of the law, CCIIO is helping consumers appeal health plan decisions, understand the Consumer Assistance Program, and more easily understand and evaluate their health insurance choices."
