A Million Seniors Just Learned Their Health Plans Are Vanishing. Enrollment Ends December 7.

Nearly 1 million members are facing a change to their Medicare Advantage coverage for 2027. Humana and UnitedHealthcare are discontinuing certain plans. For people enrolled in those plans, the practical question is not whether Medicare is disappearing. It is what coverage will replace the plan that is ending.
The enrollment deadline is December 7, 2026. That date is close enough to deserve your attention, and far enough away to give you time to compare options carefully.
Here is the short version: Humana says its plan exits affect about 600,000 members. UnitedHealthcare says a discontinued plan affects about 390,000. Both insurers cited rising medical costs and increased healthcare use. Affected members can choose another Medicare Advantage plan or return to Original Medicare during open enrollment.
The headline is alarming. The numbers are serious. But let’s keep the distinction clear: the plans are ending; Medicare itself is not.
[GRAPHIC: THE NUMBERS]
| Insurer | Members affected by plan discontinuations | Reason cited |
|---|---|---|
| Humana | Approximately 600,000 | Rising medical costs and plan changes |
| UnitedHealthcare | Approximately 390,000 | Higher costs and increased healthcare use |
| Combined | Approximately 1 million | Insurers cite cost and utilization pressures |

What is actually changing?
[ANCHOR]
Medicare Advantage, also called Medicare Part C, is private health coverage offered through Medicare-approved insurers. Humana and UnitedHealthcare are ending certain Medicare Advantage plans for 2027. They are not announcing that all their Medicare Advantage plans are ending.
That distinction matters. So does the number: the companies’ figures add up to about 990,000, commonly rounded to nearly 1 million. These are members affected by particular plan exits, not a count of people losing Medicare altogether.
If your current plan is ending, you need to review the replacement choices available to you. The options may include another Medicare Advantage plan or Original Medicare. If you choose Original Medicare and need prescription drug coverage, remember that drug coverage may require a separate Part D plan.
And here is the unglamorous part of insurance shopping: a plan from the same company is not automatically the same plan with a fresh coat of paint. Check the details.
[GRAPHIC: THE KEY DISTINCTION]
- Plan ending: Your current Medicare Advantage plan will not continue for 2027.
- Medicare ending: No. The plan changes do not mean Medicare itself is going away.
- Your next step: Compare available coverage and choose what works for your doctors, prescriptions, and budget.
Why are the insurers making changes?
[ANCHOR]
The companies point to higher medical costs and increased healthcare utilization. In everyday language, that means healthcare is being used more, and the cost of providing it has risen. Insurers say those pressures are affecting their plan decisions.
That explanation may account for why the companies are changing their offerings. It does not answer the question that matters most to you: Will your next plan cover the care and prescriptions you rely on, at a cost you can manage?
That answer depends on the specific plans available where you live and the details of your health needs. The right plan for someone in Albany, New York, may not be the right plan for someone in Tampa, Florida. Even within the same state, plan choices can vary. Use your own location when comparing options; a neighbor’s experience is not a substitute for checking your own plan information.
The deadline: December 7, 2026
[ANCHOR]
Medicare open enrollment runs through December 7, 2026. If your plan is ending, treat that as a firm date for making your decision, not a gentle suggestion from a calendar.
Your existing plan will not carry on unchanged just because you would rather not spend an afternoon comparing coverage. The official Medicare Plan Non-Renewal Notice guidance says people whose plans are leaving Medicare should get a notice from their plan in October and look for coverage for the next year.
If you received a notice, read it. Keep it. Check the plan name and the date coverage ends. If you are unsure what the notice means, call the insurer or Medicare rather than trying to decode health-plan language by candlelight.
[GRAPHIC, TIMELINE]
| Date | What it means |
|---|---|
| October 2026 | Plans that are leaving Medicare send a non-renewal notice, according to Medicare.gov |
| Through December 7, 2026 | Open enrollment: review and select 2027 coverage |
| 2027 | The discontinued plans will no longer be offered to affected members |
Your practical comparison checklist
[ANCHOR]
Before you choose a replacement, compare the coverage, not just the premium. A low monthly price can look appealing. It is less appealing if the plan does not include a provider you rely on or covers a prescription differently than you expect.
Use Medicare’s Plan Compare tool to review plans available in your area. Then verify important details directly with the plan and your providers.
1. Check your doctors and hospitals
Confirm that your primary care doctor, specialists, and preferred hospitals are in the plan’s network. If you are considering a different Medicare Advantage plan from the same insurer, do not assume the provider network is identical.
2. Check every prescription
Review your medications against the new plan’s drug coverage. Confirm whether each drug is covered and what costs or conditions apply. If you switch to Original Medicare, make a separate decision about prescription coverage, such as enrolling in a Part D drug plan if you need one.
3. Compare the costs you may actually pay
Look beyond the monthly premium. Review deductibles, copayments, coinsurance, and the plan’s maximum out-of-pocket limit. A plan that appears inexpensive at first glance may not be the least costly option across the year.
4. Compare benefits and rules
Look at what the plan covers and what requirements apply. Check whether you need referrals or prior authorization for particular services. These details can affect how you access care. Read the plan documents; do not rely on a quick summary or a familiar company name.
5. Keep a record
Save the notice from your current plan, the information you used to compare alternatives, and confirmation of any enrollment. If you speak with a plan representative or Medicare, note the date and the next step you were given.
What if you miss December 7?
[ANCHOR]
Missing the open-enrollment deadline is not a reason to ignore the situation. Medicare lists a Special Enrollment Period for people whose Medicare Advantage or Medicare drug plan is not renewed. According to Medicare’s Special Enrollment Period guidance, this opportunity runs from December 8 through the last day in February of the following year.
That is a safety net, not a shopping strategy. Do not assume that every plan change, drug coverage decision, or effective date will work the same way for every person. Read your plan’s notice and confirm what applies to you with Medicare or the insurer.
The important issue is prescription drug coverage. If you do not select appropriate coverage when your current arrangement ends, you may face a gap in drug coverage. If you move to Original Medicare, check whether you need a separate Part D plan. Do not assume a new medical plan automatically includes prescription benefits.
A simple action plan for affected members
[ANCHOR]
If you are enrolled in a Humana or UnitedHealthcare Medicare Advantage plan, take these steps now:
- Find your plan notice. Confirm whether your specific plan is ending for 2027.
- Write down the deadline. Open enrollment ends December 7, 2026.
- List what you need covered. Include your doctors, hospitals, prescriptions, and regular care.
- Compare local options. Use Medicare Plan Compare and check details with the plan.
- Decide between Medicare Advantage and Original Medicare. If you choose Original Medicare, review prescription coverage separately.
- Complete enrollment and keep confirmation. Do not leave the decision sitting in a folder marked “later.”
If a family member helps you manage paperwork, involve them early. A second set of eyes can help spot a missed prescription or provider. The person enrolled in the plan should still understand and agree with the choice.
FAQ
Are Humana and UnitedHealthcare ending all Medicare Advantage plans?

Is Medicare coverage itself ending for affected members?
No. The plan discontinuation does not mean Medicare itself is ending. Affected members can choose another Medicare Advantage plan or return to Original Medicare.

Yes, it is possible if your current coverage ends and you do not have appropriate replacement drug coverage. If you choose Original Medicare, check whether you need a separate Part D plan. Confirm your own situation with Medicare or your insurer.
What if I miss the December 7 deadline?
Medicare lists a Special Enrollment Period for people whose Medicare Advantage or Medicare drug plan is not renewed. It runs from December 8 through the last day in February of the following year. Check your notice and confirm how the rules apply to your plan.
Should I choose the lowest-premium plan?
Not automatically. Compare the premium along with provider networks, prescription coverage, deductibles, cost-sharing, and other plan rules. Your best choice depends on your needs and the plans available in your area.
Final Thoughts
[ANCHOR]
Nearly 1 million members are affected by Humana and UnitedHealthcare’s Medicare Advantage plan changes for 2027. That is a significant disruption. It is also a manageable decision if you act before the deadline and compare the coverage carefully.
Start with your non-renewal notice. Check your doctors and prescriptions. Compare available plans using your location. If you are considering Original Medicare, review drug coverage separately. Then enroll by December 7, 2026, or confirm your options if you qualify for a Special Enrollment Period.
The blunt verdict: do not let an insurer’s plan change make your choice for you by default. You still have options. Give yourself enough time to understand them.
