“…There has, therefore, been considerable speculation that the ACA's adjusted community rating regulations may result in an increase in selective self‐insurance among employers in the small group market with relatively healthier workers and, in turn, concern about the possible implications for adverse selection into the fully insured small group market with resulting higher premiums (Lucia, Monahan, and Corlette, ; Weaver and Mathews, ). Such concerns have been exacerbated by a recent estimate that 65 percent of small group employers that offer insurance coverage are expected to face premium increases due to the ACA's rating regulations (Centers for Medicare and Medicaid Services Office of the Actuary, ), qualitative evidence suggesting increased consideration of self‐insurance among small employers (Yee, Christianson, and Ginsburg, ; Gabel et al, ), and anecdotal reports of increased marketing of self‐insurance and related products to smaller employers (Hall, ; Farr, ). Furthermore, increased rates of self‐insurance among smaller employers could have potentially problematic implications for these self‐insured businesses and their workers if enrollees incur high claims and employers do not have adequate reserves or reinsurance to pay them.…”
