A Medicare agent near me can help compare coverage after a non-renewal. Blue Cross members have a December 31 deadline to avoid a gap and lost drug coverage.
What Blue Cross is cutting and why
On October 26, 2026, The Boston Globe reported that Blue Cross Blue Shield of Massachusetts is discontinuing several Medicare Advantage plans for 2027, affecting about 20,000 members, mostly in Middlesex, Essex and Worcester counties. The changes include both PPO and HMO plans. Blue Cross is also limiting enrollment in its remaining Medicare Advantage plans to very few new members, on a first-come, first-served basis. The company says the chance of securing a place in one of those plans is very low. (The Boston Globe’s report by Marin Wolf)
The Globe reported that Blue Cross incurred $275 million in losses on Medicare Advantage plans in 2024 and 2025. CEO Sarah Iselin said the cost of care exceeded the premiums the federal government paid the insurer to administer the plans. Senior vice president Krista Bowers said the company chose targeted plan cuts rather than raising premiums or reducing benefits across the board. Blue Cross has said it hopes to return to the Medicare Advantage market in 2028.
The disruption is part of a wider 2027 shake-up. Recent reports on Humana and UnitedHealthcare plan discontinuations describe nearly one million members affected nationally. In Massachusetts, Mass General Brigham Health Plan is ending all its PPO plans for 2027, Point32Health is ending one PPO plan, and Mass Advantage is leaving Medicare Advantage and shutting down. The Globe reports that more than half of Medicare-eligible beneficiaries nationally are enrolled in Medicare Advantage. A non-renewal letter in Massachusetts is therefore one local example of a broader plan-change process that members elsewhere may also need to navigate.
Why the premium nearly tripled for one retiree
The Globe reported that Tom Stambaugh, 74, of Somerville, expected his monthly premium to rise to $315 after he moved from his discontinued Medicare Advantage plan to Original Medicare and supplemental coverage. That was nearly three times his prior amount.
This is not a simple transfer of one plan premium to another. Medicare Advantage plans receive payments from the Centers for Medicare & Medicaid Services and may also charge a member premium. Original Medicare has a different structure. Someone choosing it may add a Medigap policy and a separate Part D prescription drug plan, each with its own premium and terms. The combined monthly cost can therefore be substantially different from the former Medicare Advantage premium. Actual costs vary by plan, location and individual circumstances.
The comparison should include more than premiums. Check provider access, prescription coverage, deductibles, cost-sharing, and the plan’s Summary of Benefits and Coverage. Out-of-pocket limits and other cost terms differ, so confirm them in the plan documents.
The dates that decide everything
Blue Cross’s plan-discontinuation notice says impacted members received non-renewal letters between September 30 and October 2, 2026. The notice provides the carrier’s dates and instructions for its affected members; it is not independent verification of the company’s broader claims.
The Medicare Annual Election Period runs October 15 through December 7. For an affected Blue Cross member, December 7 is not the only relevant date. Blue Cross says a member who enrolls by December 31 can select new coverage effective January 1, 2027, without a coverage gap. The period from December 8 through December 31 is the final no-gap enrollment window described in the notice.
If no new plan is selected by December 31, Blue Cross says the member will be automatically enrolled in Original Medicare on January 1 and will lose prescription drug coverage. A member may still enroll during the January 1–February 28, 2027, backup period, but the new coverage would start the month after enrollment. Delaying can leave a gap in drug coverage and may result in a Part D late-enrollment penalty.
Medicare.gov also explains that a plan non-renewal creates a Special Enrollment Period. For plans ending January 1, the period runs from December 8 through the last day of February. If no new plan is chosen, the member returns to Original Medicare. (Medicare.gov plan non-renewal information)

A non-renewal letter checklist
Use the notice and plan documents to complete these checks before enrolling:
- Confirm the end date. Read the letter and identify the exact date the current plan ends. Keep the notice as documentation.
- Check doctors and prescriptions. Confirm whether each physician, hospital and medication is covered by the replacement options. Do not assume Original Medicare or another plan will include the same providers or drug terms.
- Compare coverage and total cost. Price an alternative Medicare Advantage plan against Original Medicare with Medigap and Part D. Include premiums and expected cost-sharing.
- Check Medigap rights promptly. If the plan’s exit qualifies, a guaranteed-issue right may allow purchase of certain Medigap plans without medical underwriting. Confirm the qualifying event, eligible plans and applicable dates. The federal information describes applying as early as 60 days before coverage ends and no later than 63 days after it ends.
- Calendar both dates. December 7 is the end of AEP. For members affected by the Blue Cross termination, December 31 is the stated deadline for coverage starting January 1 without a gap.
Under federal guaranteed-issue rules, the available Medigap choices can include Plans A, B, C, D, F, G, K or L, subject to eligibility and state availability. Plans C and F generally are not available to people first eligible for Medicare on or after January 1, 2020. Check the applicable situation and policy options using Medicare.gov’s Medigap switching guidance. State rules may provide additional rights.
Coverage options after a non-renewal
| Option | What changes | Premium direction | Doctor network | Deadline |
|---|---|---|---|---|
| New Medicare Advantage plan | Replaces the discontinued plan; drug coverage depends on the plan selected | Varies by plan | Plan network and rules apply | Dec. 7 AEP; affected Blue Cross members have a Dec. 31 no-gap deadline |
| Medigap + Part D | Original Medicare plus separate supplement and prescription plans | Separate premiums; total may rise or fall | Usually broader provider choice where Medicare is accepted; confirm terms | Confirm guaranteed-issue window and enroll in time |
| MA-PD switch | New Medicare Advantage plan that includes prescription drug coverage | Varies by plan | New plan network and drug formulary apply | Dec. 7 AEP; affected members should confirm Dec. 31 timing |
What the Kling household did
The Globe described Sharon Kling, 74, of Sutton, and her husband as a couple who had been enrolled in Blue Cross Medicare Advantage plans for about a decade. After learning that the husband’s plan would end, they reviewed alternatives and found that the available Medicare Advantage choices did not meet their doctor needs. They decided to move to Original Medicare and consider Medigap.
For a household in a similar position, there are three common paths to compare. A new Medicare Advantage plan may keep coverage consolidated, but the doctor network and prescription formulary must be checked. Original Medicare with Medigap and Part D can offer a different provider-access arrangement, but typically means separate policies, bills and insurance identification numbers. A different MA-PD plan may bundle medical and drug benefits, but still requires review of providers, medicines and plan rules.
The choice involves trade-offs among premium stability, provider access and administrative simplicity. The Kling household’s concern about managing separate Medicare, Medigap and drug coverage illustrates why the number of bills and cards belongs in the comparison.
For members affected by this Blue Cross non-renewal, the December 31 date has a specific role. December 7 ends the annual election period; December 31 is the carrier’s stated final date to enroll for January 1 coverage without a gap. The letter’s instructions and the member’s eligibility should be confirmed before relying on either date.

When to bring in a Medicare agent
A Medicare agent can help compare plan details, but the available options and the agent’s carrier appointments may vary by county. Questions to ask during AEP include:
- Are you appointed with the remaining Medicare Advantage carriers in my county?
- Is my primary care provider in the plan’s network for 2027?
- Have you checked the formulary against every medication I take?
- Can you also quote Medigap and Part D options?
- Will you confirm my plan’s end date and the no-gap enrollment deadline in writing?
Before sharing Medicare numbers or other personal details, independently check the producer’s license and National Producer Number (NPN). A state regulator’s license lookup is a starting point for confirming licensing status; it does not establish that a specific plan is suitable. VerifiedAgent’s Massachusetts agent directory and state-selection page can serve as research starting points for locating agent profiles, not as proof of current licensure or plan appointments.
Frequently asked questions
What happens if a Blue Cross member does nothing?
Blue Cross says affected members who do not enroll in a new plan by December 31 will be automatically enrolled in Original Medicare starting January 1, 2027, and will lose prescription drug coverage. Later enrollment in Part D may result in a late-enrollment penalty. The member should review the plan notice and confirm the effective dates.
Is December 7 the final date to choose a plan?
December 7 is the end of Medicare’s Annual Election Period. For members impacted by the Blue Cross plan discontinuation, the carrier states that enrollment by December 31 can still provide coverage effective January 1 without a gap. This specific extension should not be assumed for unrelated plan changes.
Can someone buy Medigap after a Medicare Advantage plan ends?
A member whose plan leaves Medicare or stops providing coverage in the area may qualify for a federal guaranteed-issue right when returning to Original Medicare. Eligibility, available plan letters and timing depend on the situation. Apply as early as 60 days before coverage ends when permitted, and no later than 63 days afterward. Confirm the right directly against the federal guidance and applicable state rules.
Can Medigap be added later without medical underwriting?
Not necessarily. Outside an open-enrollment period or a qualifying guaranteed-issue situation, an insurer may be able to use medical underwriting, subject to state rules and other protections. The guaranteed-issue window related to a plan exit is time-limited. Someone who chooses Medicare Advantage now and wants Medigap later may not have the same underwriting protection.
Should members choose Original Medicare automatically?
No. Original Medicare is one option, not an automatic recommendation. Compare a new Medicare Advantage plan, Medigap with Part D, and an MA-PD plan using provider access, prescription coverage, premiums and plan terms. Confirm the effective date and enrollment deadline before making a selection.
The bottom line
Blue Cross’s 2027 plan cuts affect about 20,000 Massachusetts seniors, according to the Globe. The company’s notice sets out a December 31 deadline for impacted members seeking January 1 coverage without a gap; doing nothing means a return to Original Medicare and loss of drug coverage, according to the same notice. Compare available paths, check doctors and prescriptions, and confirm any Medigap guaranteed-issue rights within the applicable window. Plan availability and individual eligibility may differ; information should be independently confirmed before enrollment.
