Health your username December 15, 2020 The United States and New Hampshire have filed a civil antitrust action in the District of New Hampshire to halt the proposed merger of two commercial health insurance sellers, Harvard Pilgrim Health Care, Inc. and Health Plan Holdings, Inc. Monday’s filing alleges that consolidation will likely harm New Hampshire commercial group health insurance purchasers by raising prices, decreasing quality, and reducing healthcare choices. According to the filing, Harvard Pilgrim has over one million members who subscribe to its commercial group health insurance. Its customers are reportedly small and large employer groups in New Hampshire, Massachusetts, Connecticut, and Maine.
