A look at healthcare changes in 2015 and beyond

Healthcare — a sector that accounts for one-sixth of the U.S. economy, contributes an almost permanent point of tensions between economics and politics, and remains a concern for millions of families — is an enduring topic of discussion in America. That was true in 2015 and will continue to be so in 2016.

Obamacare continued to mature, but its role is still evolving.

The Affordable Care Act has brought down the percentage of uninsured Americans to about 11.5% this year from 18% in early 2013 — that’s more than 16 million adults, according to the Gallup organization. The figure corresponds to an estimate from the Department of Health and Human Services that some 17.6 million Americans have gained coverage since 2010 via the law’s provisions, which include the expansion of Medicaideligibility for low-income residents, the creation of individual insurance exchanges and the provision for youths to remain on their parents’ health plans until age 26.
