Tufts Health Plan, a Massachusetts-based health insurance company, and Harvard Pilgrim Health Care, a not-for-profit health services company based in the New England region, signed an agreement to merge. The new organization, yet to be named, will become one of the region’s largest nonprofit health services organizations, providing health coverage in all segments of the market regardless of a person’s age, income, life circumstance or health status. Financial terms were not disclosed. “Building upon our collective synergies and strengths – which includes being among the top-rated health plans in the country for quality – will unlock value that can be immediately reinvested in our members and the communities we have the privilege of serving,” said Greg Tranter, chair of the board for Tufts Health Plan. “I am excited about the future.”
