WASHINGTON—With deep divisions over President Barack Obama’s health care law reappearing in the election’s final days, a government report shows that progress in reducing the number of uninsured Americans has slowed to a crawl.
The study released Thursday by the Centers for Disease Control and Prevention suggests the 2010 law may be reaching a limit to its effectiveness.
The CDC said the number of uninsured people dipped by only 200,000 between 2015 and the first six months of this year, which it called “a nonsignificant difference.” The findings come from the National Health Interview Survey, which has queried more than 48,000 people so far this year.
While the Affordable Care Act has reduced the number of Americans without health insurance to historically low levels, continued progress threatens to stall this year amid enduring political disagreement over the government’s role in guaranteeing coverage.
“It has got to be close to tapped out,” said Dan Witters, director of a major private survey that also follows the health care law, the Gallup-Healthways Well-Being Index.
The CDC study found that during 2015, an estimated 28.6 million U.S. residents were uninsured. The corresponding number through the first six months of 2016 was 28.4 million.
The sobering numbers come as the administration seeks to whip up enthusiasm for the 2017 sign-up season, which started this week and runs through Jan. 31. The White House would like to hit a high note on health care to close out Obama’s tenure.
But premiums are going up significantly in HealthCare.gov’s subsidized markets, and consumer choice is down with fewer insurers participating. Health and Human Services Secretary Sylvia Burwell has set a goal of enrolling about 1 million more customers for 2017, but outside experts say that’s going to be a challenge. The next president will inherit a program still in search of stability.
Republican Donald Trump would pull the plug on “Obamacare,” promising to start over. Democrat Hillary Clinton has a list of ideas for making insurance more affordable and covering more people, but as president she’d need willing Republican partners in Congress and the states.
The new survey offers a hint that the nation’s historic coverage expansion may have actually gone into reverse during part of this year. An earlier CDC report covering just the first three months of this year found that the number of uninsured had been even lower, an estimated 27.3 million people—or a million fewer than the six-month figure in the latest report.
Witters said that means it’s likely that the period from April through June saw an increase in the number of people without health insurance. “It’s edged up,” he said. “These trends always ebb and flow.”
The CDC’s Emily Zammitti, lead author of the report, said the study was more of a snapshot than a trend line of progress on the uninsured. “Whether it’s plateauing or not … we can’t determine that,” she said.
The uninsured rate is 8.9 percent in the latest CDC report, a few notches higher than 8.6 percent in the earlier study.
The Obama administration said it’s betting that the 2017 sign-up season will see more progress. “We’re feeling really good that it continues to appear that the uninsured rate is below 9 percent this year,” HHS spokeswoman Marjorie Connolly said.
Another notable finding from Thursday’s report is that the share of Americans in high-deductible health insurance plans keeps increasing. That may help explain widespread anxiety about affordability at a time when overall health care spending is growing at a moderate pace.
The CDC survey defines high-deductible coverage as insurance that requires patients to pay at least the first $1,300 of annual medical expenses for an individual plan, or $2,600 for a family. In the first six months of this year, 38.8 percent of persons under age 65 were in high-deductible plans, an increase from 36.7 percent in all of 2015, the survey found.
Employers started shifting workers and their families to high-deductible plans before Obama took office, and now that’s becoming the norm. Many people are unhappy with the change, and some public-opinion experts say that helps explain the continued low ratings for Obama’s health overhaul, even if it was not the cause.
Clinton has proposed a new tax credit for people with high out-of-pocket medical costs, while Trump wants to promote interstate competition among insurers.
