Medicare Advantage

Reminder: As of Jan. 1, 2022, Harvard Pilgrim Health Care is no longer offering StrideSM (HMO) Medicare Advantage plans in Massachusetts and Maine. We continue to offer StrideSM in New Hampshire. Massachusetts StrideSM members had the opportunity to enroll in Tufts Medicare Preferred, which has earned 5 out of 5 stars from the Centers for Medicare and Medicaid Services (CMS) for an unprecedented 7th year in a row — and 7 of 10 former Massachusetts StrideSM members chose a Tufts Medicare Preferred plan for coverage this year. You can access coverage information for these members via the Tufts Health Plan provider portal.
