The U.S. is in the midst of a mental health crisis. In 2017, 47,000 Americans died by suicide and 70,000 from drug overdoses. And 17.3 million adults suffered at least one major depressive episode. The Mental Health Parity and Addiction Equity Act, a landmark law passed more than a decade ago, requires insurers to provide comparable coverage for mental health and medical treatments. Even so, insurers are denying claims, limiting coverage, and finding other ways to avoid complying with the law.
