Insurance Death Spiral

Paul Krugman explains why individual health insurance rates are going up so much:

Here’s the story: About 800,000 people in California who buy insurance on the individual market — as opposed to getting it through their employers — are covered by Anthem Blue Cross, a WellPoint subsidiary. These are the people who were recently told to expect dramatic rate increases, in some cases as high as 39 percent.

Why the huge increase? It’s not profiteering, says WellPoint, which claims instead (without using the term) that it’s facing a classic insurance death spiral.

Bear in mind that private health insurance only works if insurers can sell policies to both sick and healthy customers. If too many healthy people decide that they’d rather take their chances and remain uninsured, the risk pool deteriorates, forcing insurers to raise premiums. This, in turn, leads more healthy people to drop coverage, worsening the risk pool even further, and so on.

Now, what WellPoint claims is that it has been forced to raise premiums because of “challenging economic times”: cash-strapped Californians have been dropping their policies or shifting into less-comprehensive plans. Those retaining coverage tend to be people with high current medical expenses. And the result, says the company, is a drastically worsening risk pool: in effect, a death spiral.

Obama-style reform is the only way to solve this problem.
