Two leading Republican presidential candidates, Scott Walker and Marco Rubio, recently released concept papers that promise to provide “all Americans” with government-subsidized access to health insurance. This is a monumental development for both the campaign and for the conservative movement, one that breathes Ronald Reagan’s soul into the Republican nomination fight.

Louisiana Health Cooperative was among the 24 not-for-profit companies nationally to accept loans from the federal government to provide insurance coverage called for in the Affordable Care Act. The Metairie-based business was formed in 2011, secured $56 million in federal loans and sold plans in 2014 and 2015.

Obamacare health insurance plans limit consumers’ access to physicians and specialists, according to a new report.

Avalere Health, a strategic advisory firm, says average provider networks for plans offered on the health insurance exchanges created by Obamacare have about 34 percent fewer providers than the average commercial plan offered outside the exchange. The new data quantify anecdotal reports saying exchange networks include fewer providers than traditional commercial plans.

One of the health law’s key protections was to cap how much consumers can be required to pay out of pocket for medical care each year. Now some employers say the administration is unfairly changing the rules that determine how those limits are applied, and they’re worried it will cost them more.

To avoid the Affordable Care Act’s so-called “Cadillac tax” on rich benefit plans, companies are adding surcharges of $100 a month or more to wives and husbands of workers, hoping spouses will seek coverage elsewhere, new employer data shows.

In the wake of the Supreme Court’s decision in King v. Burwell, President Obama has claimed that Obamacare is working and here to stay.

In truth, the actual effect of the Supreme Court’s decision leaves Obamacare unchanged, and the law is certainly not working well.

Not only will Obamacare’s current political and operational problems continue, but new ones will crop up as more provisions of the law take effect.

Many Americans who bought health insurance through exchanges operated by states or the federal government have a good understanding of how their plan works, but also are afraid they can’t afford medical services, according to research published Monday by the Deloitte Center for Health Solutions.

A report scheduled for release Monday by a conservative-leaning think tank accuses state officials of misleading the federal government and the public about the Massachusetts Health Connector’s readiness to launch its new website in October 2013.

The report from the Pioneer Institute draws on public audit reports and interviews with anonymous people described as “whistle-blowers” to detail what they characterize as a bungled effort by the University of Massachusetts Medical School, software developer CGI, and the Connector to upgrade the Connector’s software in 2012 and 2013.

The Connector — designed to link people with health insurance when they don’t have another source — eventually ended its relationships with UMass and CGI.

Earlier this year the U.S. Supreme Court heard arguments in King v. Burwell, a case critical to the future of the Affordable Care Act (ACA, or so-called Obamacare). Readers interested in the details of the case should find them elsewhere. Suffice it to say here that the case concerns whether individuals can receive tax credits for buying health insurance on exchanges established by the federal government, though the text of the ACA indicates such subsidies are provided for those buying coverage through an “exchange established by the State.”

The case has the potential to invalidate substantial subsidies now being provided by federal taxpayers to millions of Americans using federal exchanges in 37 different states. Given the uncertainty created by the pending case, legislators on both sides of the aisle are considering how to react to various possible scenarios arising from a court decision. The House and Senate each recently passed budget resolutions allowing budget targets to be revised in the event of subsequent legislation modifying the ACA. The Senate resolution specifies that such legislation must be deficit-neutral.

Has the effort peaked to sign up uninsured Americans for coverage? The announcement that the nonprofit organization Enroll America is laying off staff and redirecting its focus in the face of funding cuts comes amid inconsistent sign-ups during the second Affordable Care Act open-enrollment period and concerns about affordability.

A recent New York Times analysis compared Kaiser Family Foundation estimates of potential enrollees with sign-up data from the Department of Health and Human Services. While some states that signed up few people in 2014 recovered during the 2015 open enrollment, other states lagged: “California, the state with the most enrollments in 2014, increased them by only one percentage point this year, despite a big investment in outreach. New York improved by only two percentage points. Washington’s rates are unchanged.”

Most states could not post consistent gains in both open-enrollment periods. An official from Avalere Health, a consulting firm, told the Times that she was “starting to wonder if we’ve overestimated the whole thing.”
