When Illinois’ Obamacare co-op went belly-up last month, Valerie Kincaid faced losing not just her insurance but her team of cancer doctors, too.

For six years, the 41-year-old leukemia patient has relied on doctors at Northwestern Memorial Hospital in downtown Chicago to keep her disease at bay. Once a month, she visits the hospital to receive an oral therapy that keeps her chronic lymphocytic leukemia under control and allows her to live a relatively normal life with her husband, Brian, and her 11- and 13-year-old sons.

Less than half of the approximately 27 million uninsured people in the U.S. are eligible for federal financial assistance, an analysis released Tuesday by the Kaiser Family Foundation shows.

Roughly 11.7 million, or 43 percent of that population, are not taking advantage of some sort of federal assistance to get health insurance that they are eligible for, according to the analysis. That assistant may be in the form of a subsidy to purchase a policy on the Affordable Care Act exchange or a Medicaid plan a consumer is eligible for but not signed up for.

When the Affordable Care Act was signed into law in 2010, it promised to extend health insurance to tens of millions of people. And although the law has helped push the U.S. uninsured rate down to a record low, the ACA’s new insurance markets are proving to be volatile, with insurers recording big losses and pulling out. Meanwhile, there are still millions of people without health insurance.

One key to stabilizing the law is drawing in more of those who are uninsured, particularly the younger, healthier ones. In fact, young people are the most likely to go uninsured, according to a detailed analysis by the Kaiser Family Foundation. The analysis shows that those who lack insurance cut across age and income and vary from state to state. Taking a look at who these people are can give clues to how the health law is falling short, and what can be done to fix it.

The Affordable Care Act (ACA) extends health insurance coverage to people who lack access to an affordable coverage option. Under the ACA, as of 2014, Medicaid coverage is extended to poor and near poor adults in states that have opted to expand eligibility, and tax credits are available for low and middle-income people who purchase coverage through a health insurance Marketplace. Millions of people have enrolled in these new coverage options, and the uninsured rate has dropped to the lowest level ever recorded. However, millions of others are still uninsured. Some remain ineligible for coverage, and others may be unaware of the availability of new coverage options or still find coverage unaffordable even with financial assistance.

Doctor and hospital switching has become a recurring scramble as consumers on the individual market find it difficult or impossible to stay on their same plans amid rising premiums and a revolving door of carriers willing to sell policies. “In 2017, just because of all the carrier exits, there are going to be more people making involuntary changes,” said Katherine Hempstead, a senior adviser at the Robert Wood Johnson Foundation, a New Jersey philanthropy. “I would imagine all things being equal, more people are going to be disappointed this year versus last year.”

Blue Cross and Blue Shield of Illinois will be the only insurer offering PPO health insurance plans on the state’s Obamacare exchange next year, according to information released Friday by the state Department of Insurance.

That’s down from five insurers that offered individual PPO plans on the exchange this year. Many consumers prefer PPO health plans because, unlike HMO plans, they allow patients to see specialist doctors without a referral and see physicians who are out-of-network, albeit at higher costs.

More than 250,000 people in North Carolina are losing the health plans they bought under the Affordable Care Act because two of the three insurers are dropping out — a stark example of the disruption roiling marketplaces in many parts of the country.

The defections mean that almost all of the state, from the Blue Ridge to the Outer Banks, will have just one insurer selling ACA policies when the exchanges open again for business in November. The remaining company, Blue Cross Blue Shield of North Carolina, agonized over whether to leave, too. Instead, it is raising its rates by nearly 25 percent.

A growing number of people in Obamacare are finding out their health insurance plans will disappear from the program next year, forcing them to find new coverage even as options shrink and prices rise.

At least 1.4 million people in 32 states will lose the Obamacare plan they have now, according to state officials contacted by Bloomberg. That’s largely caused by Aetna Inc., UnitedHealth Group Inc. and some state or regional insurers quitting the law’s marketsfor individual coverage.

Sign-ups for Obamacare coverage begin next month. Fallout from the quitting insurers has emerged as the latest threat to the law, which is also a major focal point in the U.S. presidential election.

Obamacare will likely see a “significant slowdown” in enrollment next year, a Thursday analysis from S&P Global Ratings projects.

The report suggests effectuated marketplace enrollment will range between 10.2 million and 11.6 million in 2017. The analysts say their forecast “is clearly a bump in the road, but doesn’t signal ‘game over’ for the marketplace.”

“The marketplace would benefit from growth in enrollment, especially if it helps improve the morbidity of the risk pool. But 2017 will likely not be the year the marketplace sees significant expansion,” the report says.

. . .

The federal government will choose health plans for hundreds of thousands of consumers whose insurers have left the Affordable Care Act marketplace unless those people opt out of the law’s exchanges or select plans on their own, under a new policy to make sure consumers maintain coverage in 2017.

“Urgent: Your health coverage is at risk,” declares a sample “discontinuation notice,” drafted by the government for use by insurers. It tells consumers that “if you don’t enroll in a plan on your own, you may be automatically enrolled in the plan picked for you.”
