On June 19, 2018, the Department of Labor (DOL) released a final rule that gives small businesses more freedom to join together as a single group to purchase health insurance in the large group market or to self-insure. These benefit arrangements are called association health plans (AHPs). By forming AHPs, small employers can avoid certain Affordable Care Act (ACA) reforms that apply to the small group market. According to the DOL, this will provide small employers with more affordable health insurance options. However, in exchange for lower premiums, AHPs may cover fewer benefits. Most AHPs will not be subject to the ACA’s essential health benefits (EHB) reform, which requires small group plans to cover a core set of items and services, such as mental health care and maternity and newborn care.
