Mental Health Parity

Left untreated, mental health and substance use disorders can be debilitating and life-threatening. Parity laws are federal and state regulations that remove limits imposed by health insurers on access to mental health benefits that are more restrictive than those imposed on medical and surgical benefits.

Prior to 1996, many Americans paid for health insurance that often did not recognize that treatment for mental health and substance use disorders is as essential as other medical treatments. The Mental Health Parity Act of 1996 required that large group health plans could not impose annual or lifetime dollar limits on mental health benefits that were less favorable than the limits imposed on medical and surgical benefits. Since then, more federal laws related to mental health parity have been passed.

For example, an important provision of the Affordable Care Act (ACA) and the Mental Health and Addiction Equity Act (MHPAEA) in 2008, ensures that health insurance plans treat mental health and substance use disorders (MH/SUD) similarly to how they treat other health conditions. An Amendment to the ACA in 2010, added this requirement of coverage to individual and small group health plans as well. In Illinois, every insurer that offers individual or group accident and health policies providing coverage for hospital or medical benefits or services for illnesses are required to provide coverage for reasonable and necessary treatment and services for mental, emotional, nervous, or substance use disorders or conditions.

The ACA requires that all health plans offered through the Marketplace cover mental health and substance use disorder services as an essential benefit. You can learn more about this coverage here. However, grandfathered plans don't have to offer some rights and protections that Marketplace plans do. Check your plan's materials or check with your employer or your health plan's benefits administrator if you are not sure of a plan's grandfathered status.

In 2015, Illinois enacted a new parity law to advance parity implementation and expand on the Federal law. The new law includes important provisions to extend and clarify coverage, educate consumers about their rights, require certain minimum treatment benefits and improve enforcement of the law.

Medicare, Medicaid and the Children's Health Insurance Program (CHIP) are not group health plans or issuers of health insurance. They are public health plans through which individuals obtain health information. These programs services comply with certain requirements of MHPAEA and are separate from Get Covered Illinois and the Department of Insurance.
