28 Medicare Advantage Plans Not Returning in Massachusetts for 2027: The List

BOSTON — Twenty-eight Medicare Advantage plans currently offered in Massachusetts will not appear in the federal government's 2027 plan file for any county in the state, according to a comparison of the CMS Medicare Advantage Landscape Source Files for 2026 and 2027. For 2027, Massachusetts residents will have 97 Medicare Advantage plans available statewide across 12 carriers.

If a plan a Massachusetts resident is enrolled in appears on the non-renewal list, that person will need to make a decision before coverage changes on January 1, 2027. The Annual Enrollment Period runs October 15 through December 7, 2026, and choices made during Medicare Open Enrollment 2027 take effect January 1, 2027.

How many Medicare Advantage plans are not returning in Massachusetts for 2027, and which carriers are affected?

Twenty-eight Medicare Advantage plan offerings in Massachusetts in 2026 are not in the 2027 CMS file for any county in the state. The affected carriers are Blue Cross Blue Shield of Massachusetts, Fallon Health, Humana, Mass Advantage, Mass General Brigham Health Plan, Tufts Health Plan and UnitedHealthcare.

The non-renewals span HMO, HMO-POS and PPO contracts, and include two Special Needs Plans from UnitedHealthcare's Erickson Advantage line (a C-SNP and an I-SNP). The full plan-by-plan list, with carrier, plan type and the number of Massachusetts counties each plan served in 2026, is shown in the table on this page. For 2027, residents of the state will still have 97 Medicare Advantage plans from 12 carriers to choose from, though exact availability varies by county.

Which non-returning Massachusetts Medicare Advantage plans served the most counties in 2026?

Several of the plans leaving the Massachusetts market served double-digit county footprints in 2026. Fallon Medicare Plus Orange (HMO) was offered in 12 counties. Medicare HMO Blue FlexRx (HMO-POS), Medicare HMO Blue ValueRx (HMO), Medicare PPO Blue ValueRx (PPO) from Blue Cross Blue Shield of Massachusetts and Tufts Medicare Preferred HMO Smart Saver Rx (HMO) were each offered in 10 counties.

Mass General Brigham Advantage, Mass General Brigham Advantage Premier and Mass General Brigham Advantage Signature (all PPO) were offered in 9 counties, and Fallon Medicare Plus Blue (HMO) and Fallon Medicare Plus Green (HMO) in 8 counties. Because a plan is offered county by county, a plan on this list may not have been offered in any given reader's county.

How can a Massachusetts member tell if their Medicare Advantage plan is leaving in 2027?

There are two reliable ways. First, federal rules require the carrier to mail an Annual Notice of Change and, for a non-renewing plan, a separate non-renewal letter before Annual Enrollment 2027 begins. Second, a member can look up the plan name, exactly as printed on the member ID card, on the list on this page.

The spelling matters. Blue Cross Blue Shield of Massachusetts, for example, has several "Medicare HMO Blue" and "Medicare PPO Blue" products on the market; only the specific FlexRx and ValueRx variants named on the list are not returning. UnitedHealthcare's Erickson Advantage Champion, Freedom, Guardian, Liberty, Liberty no Rx and Signature are all on the list, but other UnitedHealthcare plans in Massachusetts are not.

What happens if a Massachusetts resident does nothing after their plan is non-renewed for 2027?

A Massachusetts resident whose Medicare Advantage plan is non-renewed and who makes no new election will be returned to Original Medicare (Part A and Part B) on January 1, 2027. There is no automatic enrollment into another Medicare Advantage plan.

Original Medicare does not include Part D prescription drug coverage. A person who wants drug coverage in 2027 must actively enroll in either a stand-alone Part D plan or a new Medicare Advantage plan that includes drug coverage. Doing nothing can mean going into the new year without a drug plan and, later, a lifetime late-enrollment penalty.

What Special Enrollment Period and Medigap rights apply when a Medicare Advantage plan is non-renewed?

When a Medicare Advantage plan does not renew, the federal Medicare program grants the member a Special Enrollment Period that runs through the end of February 2027 to join another Medicare Advantage plan or a stand-alone Part D plan. This is in addition to the regular Annual Enrollment window that closes December 7, 2026.

The same event also triggers a federal Medigap guaranteed-issue right, meaning certain Medicare Supplement policies must be sold to the person without medical underwriting within a defined window. Massachusetts has its own Medigap rules on top of the federal floor; questions about state-specific protections should go to the Massachusetts Division of Insurance.

How can a Massachusetts resident check their own county's 2027 Medicare Advantage lineup?

The official county-level lineup for 2027 is on Medicare.gov's Plan Finder, where entering a ZIP code returns every Medicare Advantage and Part D plan available in that county for the plan year. The same information can be requested by phone from 1-800-MEDICARE, 24 hours a day, seven days a week.

Because a plan's county footprint can change from year to year, a plan that was available in one Massachusetts county in 2026 may not be available there in 2027, even if the carrier itself is still in the market.

What should a Massachusetts resident do before December 7, 2026?

Before December 7, 2026, a Massachusetts resident on Medicare should confirm whether their current plan is on the non-renewal list on this page and, if so, review the 2027 options for their specific county on Medicare.gov. A new plan chosen during Annual Enrollment 2027 begins January 1, 2027.

Even people whose plans are returning should read the Annual Notice of Change from their carrier, since premiums, drug formularies, provider networks and cost sharing can shift from one plan year to the next. Those details should be verified against the plan's Evidence of Coverage, formulary and provider directory.

Where can Massachusetts residents get free help?

Free, personalized help with Medicare questions is available directly from the federal program. Medicare.gov hosts the Plan Finder and official plan materials, and 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048, is staffed around the clock.
