Sponsors that sought recognition for the specific plans listed as minimum essential coverage ("MEC") from the U.S. Secretary of Health and Human Services and received recognition on or before December 15, 2017, shall have plans recognized as having the MEC, unless and until the plan sponsor makes a substantial change to the benefits provided (e.g., a reduction in benefits, increase in cost sharing, or the plan no longer complies with a requirement of Title I of the Affordable Care Act that applies to non-grandfathered, individual health insurance coverage as of December 15, 2017). The listing of approved plans can be accessed through the Centers for Medicare and Medicaid Services at the following web address: https://www.cms.gov/CCIIO/Programs-and- Initiatives/Health-Insurance-Market-Reforms/minimum-essential-coverage.html.
