Patient Protection and Affordable Care Act: Estimates of the Effect on the Prevalence of Employer-Sponsored Health Coverage

Government Accountability Office
The share of employers offering health coverage has generally declined in the last decade. Researchers believe that certain provisions of PPACA could affect employers’ future willingness to offer health coverage, such as the availability of subsidized coverage through new health insurance marketplaces called “exchanges” and an “individual mandate,” which will require most people to obtain health coverage or pay a tax penalty. Certain PPACA provisions are scheduled to take effect in 2014. Researchers have provided various estimates of the effect PPACA may have on employer-sponsored coverage. GAO was asked to review the research on this topic. GAO examined (1) estimates of the effect of PPACA on the extent of employer-sponsored coverage; (2) factors that may contribute to the variation in estimates; and (3) how estimates of coverage vary by the types of employers and employees that may be affected, as well as other changes employers may be considering to the health benefits they offer. GAO reviewed studies published from January 1, 2009, through March 30, 2012 containing an original numerical estimate of the prevalence of employer-sponsored coverage at the national level. These included 5 microsimulation models and 19 employer surveys. Microsimulation models can systematically estimate the combined effects of multiple PPACA provisions in terms of both gains and losses of coverage; their results are based on multiple data sets and assumptions. Surveys reflect employer perspectives; they have limits as a predictive tool in part based on varied survey methodologies and respondent knowledge of PPACA.
