The 2010 health care reform law expanded access to health insurance coverage for millions of Americans by expanding eligibility for Medicaid and developing health insurance marketplaces where eligible consumers can shop for coverage and apply for subsidies to make private health plans more affordable.
The ACA identifies 10 broad categories of services—including rehabilitative and habilitative services and devices, preventive and wellness services, and mental health and substance use disorder services—that certain health insurance plans must cover. These services are called essential health benefits (EHBs). Individual and small group plans, as well as plans covering the population that became eligible for Medicaid under the ACA, are required to cover the EHBs.
In the individual and small group markets, states establish the specific services covered in each EHB category by selecting a benchmark plan. States may update their benchmark each year, which could result in more or less generous occupational therapy benefits.
