Executives with Arizona’s nonprofit health insurance co-op said Tuesday that they have failed to come up with additional financial backing and the insurer plans to shut down all operations December 31, 2015. The announcement by Meritus Health Partners means 59,000 Arizonans it now covers need to find a new insurer by December 15 if they want coverage on January 1, 2016.

“Taxpayers should not be forced to throw good money after bad,” Grace-Marie Turner said in an interview with LifeZette. Turner is president of the Galen Institute, a not-for-profit health and tax policy research organization. “Congress would be well advised to exercise its oversight function to ensure no additional federal dollars are wasted on the program, as well as investigate how the taxpayer loans have been spent and who will pay it back,” she said.

UnitedHealth Group just announced they expect to lose $700 million in the Obamacare exchanges and are seriously considering withdrawing from the program in the coming year. Why is this happening? Because nowhere near enough healthy people are signing up to pay for the sick. The Robert Wood Johnson Foundation and the Urban Institute have come to largely the same conclusion—enrolling a total of 10 million in the exchanges, based on historic trends, would mean only about 9 million of them would be subsidy eligible. That would amount to only 38% of the 24 million people eligible for a subsidy.

UnitedHealth expects to lose $425 million on ObamaCare, including $275 million in 2016. The situation is so dire, the company took the unusual step of announcing between quarterly reports both the losses and that it may withdraw from Obamacare entirely after 2016. If United indeed pulls out, it would cause hundreds of thousands more Americans to lose their health plans.

This high incidence of failure teaches us two things. First, it should end the thinking that non-profits are somehow better than for-profits. The second lesson is for Republicans in Congress. While there are major problems with Obamacare that should be addressed, legislators shouldn’t throw away the baby with the bathwater.

When consumer advocates tried to call the obstetrician-gynecologists in the online directory of insurers’ in-network providers on the Maryland state exchange, they found that only about 22% of the 1,493 practitioners were accepting new patients, performed well-patient visits and had appointments available within four weeks. More than a third  weren’t available at all because they had left the networks, retired or were dead.

There are 499 markets for Obamacare plans in the United States. In 89 of them, the insurance company that offered this year’s best deal in the “silver” category will not be returning for 2016. The New York Times has created an interactive map showing in what areas of the United States this is the case.

Big news: UnitedHealth Group slashed its earnings outlook today, citing new problems related to Obamacare, and told investors it may exit the program’s exchanges. “In recent weeks, growth expectations for individual exchange participation have tempered industrywide, co-operatives have failed, and market data has signaled higher risks and more difficulties while our own claims experience has deteriorated,” Stephen J. Hemsley, chief executive officer of UnitedHealth Group, explained in a press release.

The Obama administration and leading members of Congress are clashing over a new Medicare payment rule that could compromise patient care, impede development of a fledgling part of the biologics industry, and make it more difficult to track patient safety issues. At issue is government payment policy for a new class of drugs called “biosimilars”—drugs that are similar but not identical to the original brand name biologic drug.

In most states, consumers with HIV or AIDS who buy silver-level plans on the insurance marketplaces find limited coverage of common drug regimens they may need and high out-of-pocket costs, according to a new analysis.
