Massachusetts Medicare Advantage Plans for Chronic Conditions in 2027: 1 C-SNPs

BOSTON — For Massachusetts residents who manage a serious ongoing health condition, Medicare's menu for 2027 includes a narrow but specific option: a Chronic Condition Special Needs Plan, or C-SNP. According to the CMS Medicare Advantage Landscape Source File for 2027, exactly one C-SNP is listed statewide in Massachusetts, offered by a single carrier and available in a handful of counties. This explainer walks through what that means, how to tell if a C-SNP fits your situation, and the dates to keep on the calendar.

What is a C-SNP in Massachusetts and who qualifies in 2027?

A Chronic Condition Special Needs Plan is a type of Medicare Advantage plan designed for people living with a specific, qualifying chronic illness, and eligibility must be verified by a health care provider. In Massachusetts for 2027, a resident qualifies to enroll only if they have Medicare Parts A and B, live in the plan's service area, and have the chronic condition the plan is built around — confirmed in writing by their doctor.

C-SNPs tailor their covered services, provider networks and drug formularies around the needs of members with that condition. Because of the verification step, enrolling in a C-SNP is a two-part process: picking the plan and getting your provider to attest to your diagnosis. If the condition cannot be confirmed within the window the plan allows, enrollment can be ended.

How many C-SNPs are offered in Massachusetts for 2027, and which carriers offer them?

For 2027, Massachusetts has 1 C-SNP listed statewide, part of a broader field of 97 Medicare Advantage plans that also includes 17 D-SNPs for people with both Medicare and Medicaid and 0 I-SNPs for people living in institutional settings. The lone C-SNP is offered by UnitedHealthcare.

That single-carrier picture is specific to the C-SNP category; the broader Medicare Advantage market in Massachusetts for 2027 includes many more carriers and plan types, listed in the full tables on this page. The point of the C-SNP count is simply to show how narrow this specialized slice is: one plan, one carrier, available in 4 counties.

Which chronic conditions are named in Massachusetts C-SNP plan names for 2027?

Under CMS rules, a C-SNP is built around a specific qualifying chronic condition, but that condition is only identified in this article when the plan's own name says so. The Massachusetts C-SNP listed for 2027 is UHC Complete Care MA-7 (HMO-POS C-SNP) from UnitedHealthcare, an HMO-POS C-SNP with drug coverage, offered in 4 counties.

The plan name here does not spell out a condition, so this article does not assign one. To confirm which chronic condition the plan serves — and whether your diagnosis qualifies — check the plan's Summary of Benefits or Evidence of Coverage on Medicare.gov, or call 1-800-MEDICARE.

Is there a Special Enrollment Period for people with a qualifying chronic condition in Massachusetts?

Yes. In Massachusetts and nationwide, people who are newly diagnosed with a qualifying chronic condition generally have a Special Enrollment Period that lets them join a matching C-SNP outside the Annual Enrollment Period. The window is tied to the diagnosis and the plan's verification process, not to the fall calendar.

Separately, the Annual Enrollment Period for 2027 coverage runs October 15 through December 7, 2026, with coverage effective January 1, 2027. People already in a C-SNP who lose eligibility — for example, if the qualifying condition can no longer be verified — are given a grace period to switch to another Medicare Advantage plan or return to Original Medicare. The specific timelines are described in the CMS enrollment-period guidance on Medicare.gov.

How do I check whether a Massachusetts C-SNP is offered in my county for 2027?

Because the single Massachusetts C-SNP for 2027 is offered in only 4 of the state's counties, the first step is checking your own county. The most reliable way is the Medicare Plan Finder at Medicare.gov: enter your ZIP code, filter for Special Needs Plans, and the tool will show whether UHC Complete Care MA-7 (HMO-POS C-SNP) — or any D-SNP you may qualify for — appears in your area.

The county-by-county tables on this page, drawn from the same CMS Landscape Source File, list availability for each Massachusetts county. If the plan is not listed in your county, your options for 2027 will come from the broader Medicare Advantage or Original Medicare menu, or from a D-SNP if you also have Medicaid.

Where can Massachusetts residents get free help comparing Medicare plans for 2027?

Free, unbiased help is available directly from Medicare. Medicare.gov hosts the Plan Finder, side-by-side comparisons, and each plan's official documents, and 1-800-MEDICARE is staffed around the clock for questions about eligibility, enrollment windows and plan details.

For a C-SNP specifically, it also helps to loop in the provider who treats your qualifying condition early, since their written confirmation is part of enrollment. The plan's own member services line, listed on Medicare.gov, can walk through the verification steps and the drug coverage included.
