Compare Medicare Supplement plans in Massachusetts. Massachusetts requires community-rated Medigap — same premium for all ages.
Massachusetts is a community-rating state for Medigap — insurers must charge the same premium regardless of age, gender, or health status. This provides significant protections for Massachusetts seniors compared to most states. You have stronger guaranteed issue rights and the premium advantage of community rating throughout your lifetime. Free Medigap counseling is available through SHINE Program at 1-800-243-4636.
Medigap (Medicare Supplement Insurance) fills the gaps in Original Medicare coverage — the 20% coinsurance, hospital deductibles, and other out-of-pocket costs that can add up quickly. In Massachusetts, Medigap plans are standardized by the federal government — Plan G from any insurer provides the same coverage — but premiums vary significantly between insurers.
Massachusetts is one of just seven states that requires community rating for Medigap — the same premium applies regardless of your age. This is a major benefit: a 75-year-old in Massachusetts pays the same Medigap premium as a 65-year-old (before insurer adjustments), while in most states, the same plan might cost 2–3x more at 75 than at 65. Shop multiple Massachusetts Medigap insurers to find the best rate, as community rating still allows premiums to vary between companies.
Plan G is the most popular Medigap option for new Medicare beneficiaries — it covers virtually everything except the Part B deductible ($257/year in 2026), providing near-complete protection from unexpected Medicare costs. Plan N offers a lower premium with the trade-off of office visit copays (up to $20) and ER copays ($50). For Massachusetts seniors with significant or unpredictable healthcare needs, the premium certainty of Medigap can be worth the higher monthly cost compared to Medicare Advantage.
Susan is 65 and enrolling in Medicare in Massachusetts. She sees her primary care doctor about 8 times per year and takes 2 maintenance prescriptions. She is comparing Plan G and Plan N. As a Massachusetts resident, she benefits from community rating — her premium will not increase with age the way it would in most states.
For a healthy 65-year-old in Massachusetts, Plan N typically saves $250–$400/year over Plan G. However, if Susan develops a condition requiring frequent specialist visits, Plan N copays can narrow or eliminate this advantage. Plan G offers complete cost predictability after the $257 Part B deductible — ideal for those who prefer simplicity or expect heavier healthcare use. In Massachusetts, both plans maintain community-rated premiums, making long-term cost comparison more straightforward than in attained-age rating states.
Open Enrollment Is Your Best Window
Your 6-month Medigap Open Enrollment Period — starting the month you turn 65 with Part B — is your guaranteed-issue window in Massachusetts. During this period insurers cannot deny coverage or charge higher premiums based on health status. Massachusetts provides additional guaranteed issue protections beyond the federal minimum, giving you more flexibility than most states.
Community Rating Advantage in Massachusetts
Massachusetts is one of seven states requiring community rating for Medigap, meaning your premium is the same whether you enroll at 65 or 85 (before insurer adjustments). This dramatically levels the playing field for older Massachusetts seniors. Premiums still vary between insurers, so get multiple quotes through SHINE Program (1-800-243-4636).

In Massachusetts, insurers must use community rating — your premium is the same regardless of age.
Medigap premiums in Massachusetts vary by plan, insurer, age, gender, and tobacco use. Since Massachusetts requires community rating, all enrollees pay the same premium regardless of age — a significant benefit for older seniors. At age 65, Plan G premiums typically range from $100–$300/month and Plan N from $80–$200/month, varying by insurer. Get multiple quotes — premiums for the same standardized plan can vary significantly between insurers. SHINE Program (1-800-243-4636) can help you compare specific quotes.
Your Medigap Open Enrollment Period is the 6 months starting the first day of the month you turn 65 AND have Part B coverage. During this window, you have guaranteed issue rights — insurers in Massachusetts cannot deny coverage or charge more due to pre-existing conditions. Additionally, Massachusetts provides stronger guaranteed issue rights than most states, offering additional enrollment opportunities throughout the year.
You can attempt to switch Medigap plans at any time in Massachusetts, but outside of your initial open enrollment period or a qualifying special enrollment period, the new insurer can use medical underwriting to deny your application or charge higher premiums based on health status. In Massachusetts, community rating requirements and stronger state guaranteed issue rights provide more opportunities to switch. Contact SHINE Program at 1-800-243-4636 before attempting to switch plans.
The choice between Medigap and Medicare Advantage depends on your individual situation. Medigap provides more predictable costs, lets you see any Medicare-accepting provider nationwide, and has no prior authorization requirements — ideal for frequent travelers, those with complex health needs, or those who want to keep specific specialists. Medicare Advantage typically has lower premiums (averaging $25/month in Massachusetts) and may include extra dental, vision, and hearing benefits, but has network restrictions and prior authorization. In Massachusetts, community-rated Medigap may be especially attractive since premiums don't increase sharply with age. Our comparison calculator above can help you evaluate which option fits your needs.
