"A majority of Americans have health insurance from the private health insurance (PHI) market. Health plans sold in the PHI market must comply with requirements at both the state and federal levels; such requirements often are referred to as market reforms. The first part of this report provides background information about health plans sold in the PHI market and briefly describes state and federal regulation of private plans. The second part summarizes selected federal requirements and indicates each requirement's applicability to one or more of the following types of private health plans: individual, small group, large group, and self-insured. The selected market reforms are grouped under the following categories: obtaining coverage, keeping coverage, developing health insurance premiums, covered services, cost-sharing limits, consumer assistance and other patient protections, and plan requirements related to health care providers. Many of the federal requirements described in this report were established under the Patient Protection and Affordable Care Act (ACA; P.L. 111-148, as amended); however, some were established under federal laws enacted prior to the ACA."
