UnitedHealthcare's 2027 Medicare Advantage plans in Boston: one new, two renamed

According to the CMS Medicare Advantage Landscape files for Suffolk County — the county Boston sits in — UnitedHealthcare is offering eight Medicare Advantage plans for 2027, up from seven in 2026, with one brand-new plan and two renamed plans carried over from this year.

What UnitedHealthcare is offering in Suffolk County for 2027
The CMS 2027 Landscape file lists eight UnitedHealthcare Medicare Advantage plans available to people with Medicare in Suffolk County next year. By plan type, that breaks down as:
- HMO: 4 plans
- HMO-POS: 2 plans
- PPO: 2 plans
All eight include Part D prescription drug coverage. Four of the eight are Dual Eligible Special Needs Plans (D-SNPs), designed for people who qualify for both Medicare and MassHealth (Massachusetts's Medicaid program). UnitedHealthcare is not offering a Chronic Condition SNP (C-SNP) or Institutional SNP (I-SNP) in the county for 2027.
The table on this page lists every UnitedHealthcare plan by name and plan type. In alphabetical order, those plans are AARP Medicare Advantage from UHC MA-0003 (HMO-POS), AARP Medicare Advantage from UHC MA-0006 (PPO), AARP Medicare Advantage Patriot No Rx MA-MA01 (PPO), AARP Medicare Advantage Patriot No Rx MA-MA2 (HMO-POS), UHC One Care MA-Y3 (HMO D-SNP), UHC One Care MA-YL (HMO D-SNP), UHC Senior Care Options MA-Y001 (HMO D-SNP), and UHC Senior Care Options MA-YL (HMO D-SNP).
What is new, what is renamed, and what is not returning
Comparing the CMS 2026 and 2027 Landscape files side by side for Suffolk County:
- New for 2027: AARP Medicare Advantage Patriot No Rx MA-MA2 (HMO-POS), with drug coverage.
- Renamed from 2026: UHC One Care MA-YL (HMO D-SNP) was UHC One Care MA-Y4 (HMO D-SNP). UHC Senior Care Options MA-YL (HMO D-SNP) was UHC Senior Care Options NHC MA-Y002 (HMO D-SNP).
- Not returning for 2027: none.
A renamed plan is not automatically the same plan with a sticker change. The benefits, provider network, drug formulary and costs can shift between plan years. That is what the Annual Notice of Change (ANOC) your plan mailed in September is for — it spells out what is different in 2027 compared with 2026.
Special Needs Plans in the UnitedHealthcare lineup
Four of UnitedHealthcare's eight Suffolk County plans for 2027 are D-SNPs: two UHC One Care plans and two UHC Senior Care Options plans. In Massachusetts, One Care and Senior Care Options are the state's integrated programs for people who have both Medicare and MassHealth, with age ranges set by the state. If you are dually eligible, these are plans designed for you; if you are not dually eligible, you cannot enroll in them.
How to check a plan against your doctors and prescriptions
Before December 7, 2026, three checks matter more than anything else:
1. Your doctors and hospitals. Go to medicare.gov, open the Plan Finder, enter your ZIP code, and look up each specific plan's provider directory. Call the office to confirm in-network status for 2027 — directories can lag. 2. Your prescriptions. Enter every drug, dose and pharmacy into the Plan Finder. The tool shows each plan's formulary tier and your estimated yearly drug cost for that plan. 3. The 2027 Part D rules that apply to every plan. The Part D out-of-pocket cap is $2,400 in 2027 (up from $2,100 in 2026). The Part D maximum deductible a plan may charge is $700 in 2027 (up from $615 in 2026). The Medicare Prescription Payment Plan, which lets you spread drug costs over the calendar year, continues to be available on request.
CMS has not yet announced the 2027 Part B standard premium and deductible, or the 2027 IRMAA income brackets. Those figures are typically published in the fall. Until they are, treat any specific 2027 Part B number you see online as not yet official.
How UnitedHealthcare fits into the Suffolk County picture
Suffolk County has 11 carriers offering Medicare Advantage plans for 2027, with 50 plans in total. UnitedHealthcare's 8 plans are one slice of that. Nothing about the number of plans a carrier offers tells you whether any single plan is right for you — that depends on your doctors, your medications, your budget and whether you want HMO, HMO-POS or PPO rules around referrals and out-of-network care.
If you do nothing
You do not have to act during the Annual Enrollment Period. If your current plan is being offered again in 2027, it renews automatically on January 1 with the changes listed in its ANOC. If a plan you are in is being discontinued, Medicare and the plan will notify you, and you get a Special Enrollment Period to pick something else. For UnitedHealthcare in Suffolk County, no plans are being discontinued for 2027.
