AUGUSTA — Maine’s Department of Health and Human Services says the state’s Medicaid claims management system has received federal certification.

Maine Health and Human Services Commissioner Mary Mayhew says it’s an important milestone because the state’s previous system had well-documented problems.

The Maine Integrated Health Management Solution was designed and implemented by Molina Medicaid Solutions, a subsidiary of Molina Healthcare.

Since September 2010, the new system has been processing approximately a million claims a month and paying nearly 3,000 providers each week.
