Officials with the Wisconsin Department of Health Services acknowledge they've had trouble with a new $64.2 million computer system that handles Medicaid services. Glitches with the automated system caused a backlog of claims, preventing the state from processing some prior authorizations for therapies and medical equipment. The agency has been unable to process about 10% of its claims for prior authorization within the 20-day time period required under state law, and some requests have taken four times longer to be approved.
