Auto injury claimants from four states seek different types of medical treatment, even though they report similar injuries. A new study of insurance claims by the Insurance Research Council
(IRC) examined auto injury claiming behavior in California, Illinois, Texas, and Washington. Comparing auto injury claims from these four tort states, IRC finds that California claimants go to chiropractors most
often, Illinois claimants are most likely to see an emergency room physician, and Washington claimants are most likely to go to general practitioners, as well as alternative medical providers, such as massage
therapists. From 1997 to 2002, per-claimant medical expenses increased the most in Texas, compared with the other three states.
