Denver-based TriZetto Group, the provider of healthcare information technology and payment management software, reported today that it has signed on Oregon healthcare provider CareOregon as a customer. TriZetto said its products are being used to process Medicaid claims, helping to improve the healthcare health plan's processing. CareOregon is a not-for-profit health plan serving low-income and vulnerable Oregonians. Financial details of the win were not disclosed. TriZetto said its products replace what was formerly a manual process handled by a third party vendor.
