Since the passage of the Patient Protection and Affordable Care Act of 2010 (ACA), there has been speculation that an increasing number of small and midsized employers would convert their health plans from fully insured to self-insured plans. The rationale has been that several of the key ACA components—creditable coverage, affordability, essential benefits, and various taxes and fees—would drive up the cost of health coverage, thus possibly making self-insurance (which is viewed by many as generally less expensive than fully-insured alternatives) a more attractive alternative for many employers. While the percentages of smaller establishments with at least one self-insured plan did indeed increase between 2015 and 2016, self-insurance in large establishments declined.
