Colossus is a computer program that is the auto industry's leading computer system for assisting claims adjusters in the evaluation of bodily injury claims from accidents.  It assists claims adjusters in interpreting value to medical reports and to look up definitions of injuries, treatments, complications and permanent impairments using AMA 4th Edition guidelines data.

As I have posted in other blogs and articles, the problem with Colossus is found in its potential for abuse. If a claims adjuster forgets, or worse, ignores a piece of medical evidence in a person's or attorney's settlement demand package, then it can skew to the injured party's detriment what the claim value of the particular injury or injuries should settle for if the case or claim went to a jury trial.
