TriZetto Buys MDE to Improve Encounter Services


Health payer software vendor The TriZetto Group has acquired transactions processing vendor Medical Data Express for an undisclosed sum.

Chandler, Ariz.-based MDE processes encounter data for Medicare and state Medicaid plans. Providers submit an encounter file to a payer, which then submits the file to MDE, or licenses and uses the vendor’s software. The MDE software applies CMS edits and reformats encounters in the file before it is entered into a Medicare or Medicaid plan’s adjudication engine.

The acquisition expands TriZetto’s services to Medicare and Medicaid managed care plans, particularly with establishment of Medicare Advantage plans. More information is available at
