rescission: canceling coverage: 50% chance if you are in the top 1% most sick people ???!!!

Unconscionable Math � Taunter Media

The House hearings on rescission – the retroactive cancellation of individual health insurance policies – were over a month ago, but after its initial run through Daily Kos it seems to have waited a bit before popping up on Baselineand Slate. James Kwak at Baseline described the practice as rare, affecting only 0.5% of the population. The faint light bulb above my head began to flicker:could that be true…that’s not rare – that is amazingly common.

...

What tangled webs we weave…

To understand why 0.5% of the people Assurant covers is a lot of people – a jarring, terrifying, probably criminal lot – you need to understand a little bit of math. You need to understand just enough math to understand what Don and his legal team are not telling you. You need to understand conditional probability. And the folks at Assurant are counting on the fact that you don’t.

...

Here’s the health care nuance (2005 HHS report based on 2002 data):

Bar graph shows percent of total expenditure by percent of population: Top 1% (greater than or equal to $35,543), 22%; Top 5% (greater than or equal to $11,487), 49%; Top 10% (greater than or equal to $6,444), 64%; Top 20% (greater than or equal to $3,219), 80%; Top 50% (greater than or equal to $664), 97%; Bottom 50% (less than $664), 3%.

Half of the insured population uses virtually no health care at all. The 80th percentile uses only $3,000 (2002 dollars, adjust a bit up for today). You have to hit the 95th percentile to get anywhere interesting, and even there you have only $11,487 in costs. It’s the 99th percentile, the people with over $35,000 of medical costs, who represent fully 22% of the entire nation’s medical costs. These people have chronic, expensive conditions. They are, to use a technical term, sick.

...

It should be fairly clear that the people who do not file insurance claims do not face rescission. The insurance companies will happily deposit their checks. Indeed, even for someone in the 95th percentile, it doesn’t make a lot of sense for the insurance company to take the nuclear option of blowing up the policy. $11,487 in claims is less than two years’ premium; less than one if the individual has family coverage in the $12,000 price range. But that top one percent, the folks responsible for more than $35,000 of costs – sometimes far, far more – well there, ladies and gentlemen, is where the money comes in. Once an insurance company knows that Sally has breast cancer, it has already seen the goat; it knows it wants nothing to do with Sally.

If the top 5% is the absolute largest population for whom rescission would make sense, the probability of having your policy cancelled given that you have filed a claim is fully 10% (0.5% rescission/5.0% of the population). If you take the LA Times estimate that $300mm was saved by abrogating 20,000 policies in California ($15,000/policy), you are somewhere in the 15% zone, depending on the convexity of the top section of population. If, as I suspect, rescission istargeted toward the truly bankrupting cases – the top 1%, the folks with over $35,000 of annual claims who could never be profitable for the carrier – then the probability of having your policy torn up given a massively expensive conditionis pushing 50%. One in two. You have three times better odds playing Russian Roulette.

...

It is in the health insurer’s interest to have application fraud, not only because it saves time and expense on the front end, but also because it lets them get out of any policy that isn’t going well for them. If the health insurer had to verify the information – if, in essence the insurance company had to behave as an accredited investor with adequate expertise to make a decision without reliance – it wouldn’t have the opportunity to bail out. It would catch more genuine liars, but many of these liars would have turned out to be healthy, profitable customers, and what the carrier really wants is a population devoid of expensive claims, not devoid of liars. ...
