Fair Isaac Medical Bill Review Services Delivers More Efficient Auto Injury Claims Processing For OneBeacon

SAN RAFAEL, Calif.--Sept. 11, 2003--Fair Isaac Corporation , the leading provider of analytics and decision technology, today announced that OneBeacon Insurance Group is implementing Fair Isaac's medical bill review services for Personal Injury Protection (PIP) and med-pay bills. The agreement is the third between OneBeacon and Fair Isaac within the past year, and expands the reach of Fair Isaac's outsourced medical bill review technologies in the insurance industry.

Fair Isaac's medical bill review services provide OneBeacon with powerful new tools for reducing claims costs. Fair Isaac's medical bill review software technologies increase productivity and consistency for insurers by automating the labor-intensive process of reviewing and repricing medical bills to levels consistent with state laws. The software also automatically applies preferred provider organization (PPO) discounts to maximize savings.

"We are proud to expand our partnership with one of the Northeast's leading property-casualty insurance carriers," said Sean Downs, vice president of Healthcare and Insurance at Fair Isaac. "OneBeacon can now tap into the operational and cost benefits of our claims processing solutions as we continue to increase the impact of Fair Isaac's analytics and services within the insurance industry."

In 2002, OneBeacon contracted with the Fair Isaac Insurance Service Bureau for outsourced workers' compensation medical bill review, and licensed Fair Isaac MIRA(R) Claims Advisor For Reserving software to optimize their workers' compensation loss reserves.

"OneBeacon is already realizing the anticipated savings and productivity gains from outsourcing our workers' compensation bill review with Fair Isaac last year," said Peter McCarron, vice president of Workers Compensation Claims at OneBeacon. "By outsourcing our PIP and med-pay bill review processes, we expect to further increase the efficiency of our claims processing capabilities and thereby improve our financial performance."

The Fair Isaac Insurance Service Bureau provides complete outsourced medical bill review and managed care services for workers' compensation and automobile medical injury insurance clients, including insurance carriers, third-party administrators and self-insured corporations. With two locations across the U.S., the Fair Isaac Insurance Service Bureau combines an experienced team of bill review experts, including doctors and nurses, to provide maximum savings on every medical bill reviewed.

The Insurance Service Bureau utilizes an array of powerful Fair Isaac bill review technologies to automate the review of a significant percentage of medical bills without human intervention. This includes the company's AutoAdvisor(R) and CompAdvisor(R) software to automate the review and repricing of medical bills to the lowest commonly acceptable amount possible and provide additional preferred provider organization (PPO) medical discounts; intelligent scanning and optical character recognition (OCR); and the company's powerful Capstone(R) workflow software. The combination of Fair Isaac's advanced imaging, workflow and decision management tools allows for significantly faster, consistent and more accurate bill review.

Fair Isaac software products and services process more than $4.4 billion annually in property and casualty claims. They are in use in the operations of nine of the top ten property/casualty carriers and 65 percent of the nation's state workers' compensation funds.

OneBeacon's bills will be processed at Fair Isaac's Insurance Service Bureau centers in Coppell, Texas and Irvine, California.
