The Centers for Medicare & Medicaid Services announced the creation of 106 more accountable care organizations Thursday. Among them were nine groups based in Massachusetts or with some operations here, including organizations affiliated with Metro West Medical Center, Baystate Health, Lahey Health, Winchester Hospital, and Cambridge Health Alliance.

Created under the Affordable Care Act, the program pushes doctors and hospitals to collaborate “to give people with Medicare the high-quality care they expect and deserve” and to save money for the government program that provides coverage for the elderly and disabled, Health and Human Services Secretary Kathleen Sebelius said in a press release.
