( CNN ) -- Days ahead of the one-year anniversary of the rollout of HealthCare.gov , the Affordable Care Act 's health care exchange website that was originally plagued with numerous technical glitches , the Department of Health and Human Services has released a report highlighting the impact of the law on hospital costs . HHS , which oversees the implementation of the Affordable Care Act , said the report projects hospitals will save $ 5.7 billion in uncompensated care costs in 2014 . Uncompensated care costs are those incurred by the hospitals that wo n't be reimbursed . The report says $ 4.2 billion of the savings come from the 27 states -- plus Washington , D.C. -- that implemented a Medicaid expansion as part of the health care act , with the additional $ 1.5 billion in savings spread across the states that opted out of the expansion . `` Hospitals have long been on the front lines of caring for the uninsured , who often can not pay the full cost of their care . Today 's news is good for families , businesses and taxpayers alike , '' said HHS Secretary Sylvia Burwell before the report 's release . The number of hospital visits by patients who are uninsured has fallen , the report found , and the general hypothesis is that because of the increase in individuals with health care insurance , the instances of uninsured hospital trips are less frequent , and that will continue to be a trend . Study : Obamacare gave 10 million Americans health insurance . However , the report noted that `` the extent of this reduction is an empirical question , '' because there are a number of factors that will contribute to these costs , including `` the extent to which newly insured individuals are able to meet the cost-sharing obligations imposed by their plans . '' Asked if these figures might encourage governors of states that originally opted against the expansion to revisit the option , Burwell said the issue was a very individualized one . `` The medicaid issue is retail , '' she told reporters at a briefing on Wednesday . `` It is state by state . '' But the issue is also political . Of the 21 states that are not implementing the expansion , all but two of them -- Missouri and Virginia -- have Republican governors . CNN poll : Is Obamacare working ? Burwell expressed cautious optimism that the recent decision by Republican Pennsylvania Gov . Tom Corbett to move forward with the Medicaid expansion could influence other GOP governors . `` I think it 's true that people are influenced by people who are like them '' she said in response to a question about whether Corbett 's decision might inspire others . `` I think the more that we are able to attract conservative Republican governors , the more that those who have very strong feelings will perhaps listen . '' According to numbers provided by HHS , a little over 10 million previously uninsured adults have gotten health care coverage since enrollment began last year .
