Medical Treatment for Similar Auto Crash Injuries Varies from State to State, Industry Study Reports

August 8, 2005

Auto injury claimants from four states seek different types of medical treatment, even though they report similar injuries, according to a study of insurance claims by the Insurance Research Council. The study examined auto injury claiming behavior in California, Illinois, Texas and Washington.

Comparing auto injury claims from these four tort states, IRC found 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.

The recently released IRC study, Analysis of Auto Injury Insurance Claims in Four Tort States, examines detailed information from auto injury claims that closed with payment in four states with similar auto insurance regulations: California, Illinois, Texas and Washington.

The IRC analysis of
reported bodily injury liability (BI) claims in these four states revealed the following differences and similarities:

• In each of the four states, neck or back sprains were the most serious injury for at least seven in 10 BI claimants and at least three-quarters suffered no disability from the accident.

• In California, 57 percent of BI claimants went to a chiropractor com pared with 28 percent in Illinois, 43 percent in Texas and 46 percent in Washington.

• More than half (53 percent) of California BI claimants’ medical fees came from chiropractors, compared

with 26 percent in Illinois, and 44

percent in both Texas and Washington.

• From 1997 to 2002, average claimed

medical expenses increased by 39

percent in Texas, compared with 25

percent in California, 24 percent in

Illinois and 9 percent in Washington.

Over this same time period, medical cost

inflation was 22 percent, according to

the CPI.

Similar patterns emerged in first-party medical payments claims in California and Illinois, along with personal injury
protection claims in Texas and Washington.

In all four states, average BI payments exceeded claimed economic losses, reflecting auto insurance payments for general damages, sometimes referred to as pain and suffering. In 2002, claimed economic losses, mainly consisting of medical expenses, were highest in Illinois and California BI claims, averaging $5,506 and $5,409 respectively.

The corresponding average insurance payments to BI claimants were $7,850 in Illinois and $7,830 in California. In comparison with these two states, Texas claimants averaged lower reported economic losses ($4,483) and BI payments ($5,768). Washington BI claimants’ economic losses averaged $3,833, the lowest of the four states. However, average BI payments were $7,594 in Washington, near the levels in Illinois and California.

“Auto insurance claimants often seek different types of medical treatment for the same type of injuries, and this apparently varies by the state in which the accident occurs,” explained Elizabeth Sprinkel, senior vice president of the IRC. “Regardless of treatment type, however, insurers’ BI payments exceeded claimed expenses on average in each of these four states.”
