The Uninsured Rate Is Going Up Again

The national uninsured rate has started climbing back up amid higher costs for health insurance and uncertainty about the future of the Affordable Care Act, according to Gallup-Sharecare Well-Being Index survey findings released Friday.

In the three-month period that ended Sept. 30, 12.3 percent of American adults had no health coverage, a 0.6 percentage point increase from the prior quarter and a 1.4 percentage point rise since the end of last year, the Gallup-Sharecare Well-Being Index shows. That represents 3.5 million fewer Americans with health coverage between Dec. 31, 2016, and Sept. 30, 2017, according to Gallup, andcontinues a trendthat started earlier this year.

TheAffordable Care Actbrought abouta historic declinein the uninsured rate through its expansion of Medicaid coverage to low-income adults and its introduction of subsidized private health insurance for low- and middle-income families beginning in January 2014. From 2014 through 2016, the share of Americans without health coverage fell significantly, reaching 10.9 percent at the end of last year.

Since then, the percentage has crept higher, but still remains far lower than the 18 percent recorded at the end of 2013, just before the Affordable Care Act’s coverage expansion began.

The Gallup report doesn’t include data proving the causes of the uptick in the number of uninsured, but the likeliest explanation includes a mix of factors that include shortcomings of the Affordable Care Act’s health insurance marketplace itself, andactions takenby PresidentDonald Trumpand theRepublican-led Congress.

Although premiums for people who get health benefits from their employers ― the most common source of health coverage in the United States ― haveheld relatively steadyin recent years, the same can’t be said for the price of health insurance from an exchange or bought directly from an insurer. The share of Americans in this segment of the insurance market without health insurance increased from 20 percent at the end of 2016 to 21.3 percent as of Sept. 30, Gallup reports.

Premium increases on the Affordable Care Act’s health insurance exchangesrose sharplyin many parts of the country from 2016 to 2017, putting coverage out of reach for households that qualified for little or no financial assistance. Those who are eligible for tax credits to reduce their monthly insurance bills generally are shielded from rate hikes because their subsidies increase to compensate, but those who must pay full price bear the brunt of the rate hikes. Even so, the uninsured rate rose slightly more last quarter for low-income households than for higher earners.

In addition to those underlying issues in the market regulated by the Affordable Care Act, Trump and theGOPCongress havecreated uncertaintyabout the state of the exchanges and the future of the health care system that likely depressed enrollment.

The Housepassed legislationthis spring to repeal the Affordable Care Act, and theSenatedebated but ultimatelyfailed to passa similar bill. Those bills would’ve increased the number of uninsured Americans by more than 20 million, according to Congressional Budget Office analyses. These congressional actions, plus theTrump administrationindicating itmight not fully enforcethe law’s individual mandate that most U.S. residents obtain health coverage or face tax penalties, could have contributed to the decline in the number of people covered.

The uninsured rate very probably will continue to increase in future months if things remain on their present course.

Trump’s threats ― on which he followed through this month ― tocut off repaymentsto health insurance companies serving low-income people caused insurers to institute verylarge premium hikesin most states for next year. The Trump administration also hasclearly signaledit will carry out a much less robust effort to enroll people in health coverage during the open enrollment period that begins Nov. 1 and ends Dec. 15 in most states, which risks lower sign-up numbers for 2018.

A bipartisan group of senators led by Health, Education, Labor and Pensions Committee ChairmanLamar Alexander(R-Tenn.) and ranking memberPatty Murray(D-Wash.)introduced legislationThursday to stabilizing the health insurance exchanges. But even ifCongresspasses this bill and Trump signs it before the end of the year, it would have little effect on exchange plan premiums next year, which already are all but locked in.
