Top Medicare Advantage Insurers in Massachusetts
These insurers represent the largest market share for Medicare Advantage plans in Massachusetts. Plan availability, benefits, and networks vary by county — a plan available in Boston may not be offered in rural areas. Star ratings and plan availability change annually. Compare specific plans using the official Medicare Plan Finder during Open Enrollment (October 15 – December 7).
What This Means for Massachusetts Enrollees
Medicare Advantage penetration in Massachusetts is below the national average, likely because plan choice is thinner in rural areas. Original Medicare + Medigap is the dominant choice, giving nationwide provider access at the cost of higher monthly premiums.

Common Medicare Questions — Massachusetts
When can I enroll in Medicare in Massachusetts?
Your Initial Enrollment Period is a 7-month window around your 65th birthday (3 months before, your birthday month, and 3 months after). Missing this creates permanent late-enrollment penalties. If already enrolled, Annual Open Enrollment (Oct 15–Dec 7) lets you change plans; Medicare Advantage Open Enrollment (Jan 1–Mar 31) lets you switch MA plans or return to Original Medicare. See our enrollment guide.
Should I choose Medicare Advantage or Original Medicare + Medigap in Massachusetts?
Depends on trade-offs. MA plans have moderate premiums and often bundle dental/vision/hearing. Original Medicare + Medigap costs more per month but gives you access to any doctor nationwide who accepts Medicare. In Massachusetts specifically, MA penetration is 25% — telling you what most residents pick. See our side-by-side comparison.
How do I avoid Medicare scams during Open Enrollment?
Aggressive sales calls spike during Oct–Dec. Medicare never calls you unsolicited. Only comparison tool you should trust is medicare.gov Plan Finder. For free neutral counseling, use Massachusetts's SHIP program at 1-800-243-4636. Report scam calls to 1-800-MEDICARE.
Does Massachusetts help low-income seniors with Medicare costs?
Yes. Massachusetts participates in the federal Medicare Savings Programs (MSP), which help pay Part B premiums for eligible lower-income seniors. Extra Help (LIS) also reduces Part D drug costs. Apply through your state Medicaid office or SSA (1-800-772-1213).
What if my doctor isn't in the Medicare Advantage plan network in Massachusetts?
Under HMO plans, you'd generally need to switch doctors or switch plans (either at next Open Enrollment or a Special Enrollment Period if you qualify). Under PPO plans, you can typically see out-of-network providers at higher cost. Before enrolling, always call your doctor's office directly to confirm they're in-network for that specific plan in the current year.
