The usual suspects have been attacking Obama for “demonizing” insurance companies; but saying that people do terrible things isn’t demonization if they do, in fact, do terrible things.

And health insurers do, because they have huge financial incentives to act in an inhumane way — most obviously, by revoking coverage when people get sick, using whatever rationale they can devise.

Read this report by Murray Waas on Assurant Health (previously called Fortis), which used a computer algorithm to identify every client with HIV, then systematically revoked coverage on the flimsiest of grounds — and appears to have systematically hidden any paper trail showing how it made its decisions:

The South Carolina Supreme Court, in upholding the jury’s verdict in the case in a unanimous 5-0 opinion, said that it agreed with the lower court’s finding that Fortis destroyed records to hide the corporation’s misconduct. Supreme Court Chief Justice Jean Hoefer Toal wrote: “The lack of written rescission policies, the lack of information available regarding appealing rights or procedures, the separate policies for rescission documents” as well as the “omission” of other records regarding the decision to revoke Mitchell’s insurance, constituted “evidence that Fortis tried to conceal the actions it took in rescinding his policy.”

And what basis did the company use for revoking coverage?

Fortis canceled Mitchell’s health insurance based on a single erroneous note from a nurse in his medical records that indicated that he might have been diagnosed prior to his obtaining his insurance policy. When the company’s investigators discovered the note, they ceased further review of Mitchell’s records for evidence to the contrary, including the records containing the doctor’s diagnosis.

Still, this must have been an outlier, a scuzzy company that wasn’t at all typical, right? But in that case, why was the CEO one of the people who testified on behalf of the insurance industry?

On June 16, 2009, the House Energy and Commerce Committee, held a hearing on the practice of rescission by health insurance companies, and among the industry executives who testified was Don Hamm, the CEO and President of Assurant Health. Hamm insisted before the committee that rescission was a necessary tool for Assurant and other health insurance companies to hold the cost of premiums down for other policyholders. Hamm asserted that rescission was “one of many protections supporting the affordability and viability of individual health insurance in the United States under our present system.”

And as the story points out, the evidence is that the overwhelming majority of rescissions, not just at Assurant but across the board, are, in fact, without justification.

The crucial thing to understand is that depending on how a few Democrats vote sometime soon, stories like this will either cease happening — or continue, and get much worse. The proposed health care reform would end discrimination based on pre-existing conditions, and therefore end the threat of rescission as well.

And to repeat what I and other have repeatedly explained, you need the whole package to make this work. You can’t end discrimination based on medical history unless you require that health as well as sick people have insurance, to broaden the risk pool. And you can’t mandate coverage unless you provide aid to those who otherwise couldn’t afford it.

Right now, we have a system that creates huge incentives for bad, one might say demonic, behavior: Assurant made $150 million by revoking coverage, almost always without cause. We can end all of that — not in some indefinite future, but with a single vote right now.

Just do it.
