ZIP codes and premiums
Often, California has been in the lead when it comes to legislating for fairness. When a service industry is acting in an arbitrary way and damaging the interests of consumers, you can usually rely on Sacramento to do something about it. So, for example, the Insurance Commissioner instructed auto insurance companies not to rely on ZIP codes when writing policies. The real basis on which to assess risk should always be the individual driver. It's fair to look at the person's experience, driving record, how far he or she drives every year, etc. That way you reward the good drivers with lower premiums and hit the bad drivers with higher premiums. This ends the discriminations of higher premiums for people living in predominantly black or Latino communities.
It would be great if we could see this change sweeping across the US, not just in auto insurance, but for all classes of insurance. Unfortunately, the insurance industry has fought the change tooth and nail wherever it has been proposed. Lobbyists with deep pockets have been able to keep the legislators at bay. The ZIP code approach remains the norm.
The most recent piece of research comes out of Chicago and relates to health plans. It seems it's cheaper to live in the suburbs. The research used just over 3,000 ZIP codes in the Chicago area and, when analysing the rates charged, found that people living in the blue-collar suburbs west and south of Chicago paid almost 25% less for their insurance than those living in the downtown areas. Similarly, the residents of the northern suburbs paid about 15% less. Spread the net more widely and it turns out that everyone living between 15 and 25 miles from the downtown area pays an average of 13.5% less, while those who have moved 25 to 40 miles out of the city pay an average 25% less.
There are obvious explanations. The hospitals and clinics in different areas attract doctors and healthcare providers with different levels of experience and expertise. Operating costs will also change with local conditions. The level of support for public facilities and programs from local government naturally varies depending on the local tax take and political factors. These affect the rates for services the insurers can negotiate with the local provider networks. And then there are all the intangible factors based on the wealth or poverty of an area, the percentage of people without current health insurance, and so on. Put everything together and profiling by geography may produce very different results. This leaves us with an uncomfortable reality. As it stands, the health insurance industry is unregulated. It can charge what it likes using whatever factors it wishes to consider significant. As and when the healthcare reforms pass through Congress, some practices that produce unfairness will disappear, e.g. no more discrimination based on gender, no more discrimination by denying coverage to people with pre-existing conditions, no more caps on lifetime benefits, and so on. But the ZIP code abuse will not be affected. No matter where you live, you will be judged not on your actual health records but the accident of your address. Perhaps you should consider relocating to a better area to get the best health insurance rates.
