The scale is real. KFF identifies 3.1 million enrollees in Medicare Advantage drug plans that end after 2026.
This guide covers how to verify your notice, what happens by default, your enrollment rights, how to compare replacements, and where to find trustworthy help. Confirm all deadlines for your plan year at Medicare.gov.
Key Takeaways
- Confirm your plan's final coverage date, your Special Enrollment Period, and required actions using official sources.
- Compare another Medicare Advantage plan, Original Medicare with Part D, and Medigap where eligible.
- Check doctors, prescriptions, pharmacies, referrals, and out-of-pocket exposure before enrolling.
- Don't assume drug or supplemental coverage will be arranged for you.
Why Medicare Advantage Plans End
What "your plan is ending" can mean
The phrase covers several different situations:
- The insurer nonrenews its contract at the end of the term
- The plan stops serving certain counties, even if it stays open elsewhere
- CMS terminates the contract for specified failures
- You move out of the plan's service area
- The plan stays but changes its costs or benefits significantly
The insurer usually makes the exit decision, not you. CMS sets the rules and oversees contracts. Your official notice states the actual reason, so read it first.
Why insurers pull back
Kaiser Family Foundation (KFF) points to local market conditions, cost pressures, company strategy, and profit expectations. Payment policy matters too: CMS projected average Medicare Advantage payments would rise 5.06% in 2026. That is context, not proof of why any one insurer left.
Who is affected
Impact varies by county, insurer, and plan type. For 2027, KFF finds 193 counties without a general-enrollment Medicare Advantage drug plan, up from 123 in 2026. National averages tell you little. Your notice and your county's Plan Finder results do.
When a plan ends, caregivers often handle the paperwork. They can gather notices, medication lists, provider names, and enrollment confirmations. Leave the coverage decision to the beneficiary and a qualified counselor.
What Happens When Your Medicare Advantage Plan Ends?
Read the notice carefully
Look for:
- The last day of coverage
- Whether the plan leaves your area or ends entirely
- Replacement options and enrollment instructions
- Special Enrollment Period dates
- Plan and Medicare contact information
Keep the notice and all related mail. It can document your Special Enrollment Period and guaranteed-issue Medigap rights. Note that the annual notice of changes, due by September 30, is a separate document and doesn't by itself mean your plan is ending.
What happens by default
If you make no other election, coverage generally returns to Original Medicare Parts A and B. Standalone Part D and Medigap are not ordinarily added automatically. Some Extra Help beneficiaries are the exception, since CMS has reassignment procedures for them.
Dental, vision, and other extras that came with your plan may disappear. Verify each piece separately.
Your Special Enrollment Period
| Ending event | Enrollment window |
|---|---|
| December 31 nonrenewal or service-area reduction | December 8 through the last day of February |
| Plan ends its contract | Two months before through one month after the end |
| CMS terminates the contract | One month before through two months after |
For annual nonrenewal, a December 8-31 election starts January 1, a January election starts February 1, and a February election starts March 1. Your notice controls your exact dates. A late election means a start date after January 1, so plan ahead.
Medigap protections
Losing Medicare Advantage can create guaranteed-issue rights for certain Medigap policies. The application window generally opens 60 days before coverage ends and closes 63 days after coverage ends. During it, insurers cannot deny the protected policy, exclude pre-existing conditions, or charge more for health problems.
Not every plan letter is available to everyone. People new to Medicare on or after January 1, 2020 cannot buy Plans C or F.
State rules differ. Virginia's regulation expressly covers qualifying Medicare Advantage termination. West Virginia's 2026 bulletin describes a separate replacement right that requires 24 months of continuous Medigap coverage, so it isn't an entry right for people leaving Medicare Advantage.
Protect prescriptions and ongoing care
Going 63 or more consecutive days without Part D or creditable coverage can trigger a lifetime late-enrollment penalty. It equals 1% of the national base premium ($38.99 in 2026) for each uncovered month.
New plans must offer a transition process:
- Part D plans give a temporary supply of eligible non-formulary drugs during the first 90 days
- New coordinated-care Medicare Advantage plans must honor an active course of treatment for at least 90 days
If you're mid-treatment, ask both plans about prior authorizations, refills, and referrals.
A Step-by-Step Action Plan
- Confirm the plan is ending. Compare your notice with your Medicare.gov account or Plan Finder. If they conflict, call 1-800-MEDICARE (1-800-633-4227). Record the plan name, reason, final date, and every deadline.
- Build a coverage checklist. List your doctors, specialists, hospitals, pharmacies, medications and dosages, upcoming care, travel habits, and budget. Mark what's essential. A low premium shouldn't be the only factor.
- Compare plans. Use official tools, not ads or unsolicited calls. Call your doctors directly, because online directories and formularies can be wrong.
- Apply on time. Use an approved channel, save the confirmation number, and follow up if your ID card doesn't arrive.
- Prevent gaps. Ask the new plan, your pharmacy, and your prescriber about formulary changes, refill timing, and referrals. Don't stop medication or cancel coverage on a verbal promise. Confirm the effective date first.
- Check affordability. Look at premiums, deductibles, copays, and drug costs together.
If the total is hard to manage, check these 2026 federal income limits for assistance:
| Program | Individual / couple | Helps with |
|---|---|---|
| Extra Help | Income $23,940 / $32,460 | Part D costs |
| QMB | Monthly income $1,350 / $1,824 | Premiums and cost sharing |
| SLMB | Monthly income $1,616 / $2,184 | Part B premium |
| QI | Monthly income $1,816 / $2,455 | Part B premium |

Compare Your Main Coverage Options
Option 1: Another Medicare Advantage plan
This keeps the managed-care structure and may keep dental, vision, or hearing extras. It also has an annual medical out-of-pocket limit, capped at $9,250 in network for 2026.
A replacement from the same insurer is not automatically equivalent. Check the network, formulary, referral rules, and prior authorization requirements. KFF found that Medicare Advantage networks included about 48% of physicians available to Traditional Medicare enrollees locally.
Option 2: Original Medicare with Part D
You can see any participating Medicare provider nationwide, usually without referrals or prior authorization. But there's no annual out-of-pocket cap, and you need a standalone Part D plan.
2026 benchmarks: Part B premium $202.90 a month, Part B deductible $283, then generally 20% of approved amounts. Part A carries a $1,736 deductible per benefit period.
Option 3: Add Medigap when eligible
Medigap supplements Original Medicare and helps with covered cost sharing. New policies don't include drug coverage, so Part D is separate. Outside guaranteed-issue rights or open enrollment, insurers may use medical underwriting and can refuse you.
Compare total value
Premiums are only one piece. Weigh these:
- Provider access
- Drug costs
- Deductibles and coinsurance
- Worst-case exposure
- Extras and travel needs
- Expected healthcare use
Build a side-by-side using your real doctors, medications, and treatment schedule.
Match the choice to your situation
- Chronic conditions or specialists: network and prior authorization matter most.
- Rural area: check whether any plan has your providers.
- Frequent travel: national access favors Original Medicare.
- Limited income: screen for Extra Help and Medicare Savings Programs.
- Heavy dental, vision, or hearing use: compare those benefits closely.
The best choice is personal and can change when a plan's network or costs change.
Where to Get Reliable Help
Start with free official resources
- Medicare.gov and Plan Finder verify plan availability, enrollment periods, and Part D options
- 1-800-MEDICARE confirms your status independently
- State Health Insurance Assistance Programs (SHIP) offer unbiased one-to-one counseling
Virginia's VICAP is 1-800-552-3402. West Virginia's SHIP is 1-877-987-4463.
Evaluate private advisers carefully
Ask any agent:
- Are you licensed in my state?
- Which carriers and plan types can you discuss?
- How are you paid?
- Can you explain Original Medicare, Part D, and Medigap, not just Medicare Advantage?
Medicare prohibits unsolicited home visits, and agents generally can't cold-call you about Medicare Advantage or Part D. The FTC has warned about callers claiming you need a new Medicare card. Cards are free.
FTC's alert advises hanging up and calling 1-800-MEDICARE yourself. Never give your Medicare number or bank details to an unexpected caller.

Frequently Asked Questions
Who is canceling Medicare Advantage plans?
Individual insurers can nonrenew a plan, leave a county, or end a contract. CMS can also terminate contracts for specified failures. Your notice states the reason.
What happens when a Medicare Advantage plan is terminated?
Without another election, you generally return to Original Medicare. Drug and supplemental coverage must be arranged separately. Confirm dates with Medicare.gov or 1-800-MEDICARE.
How can I tell whether my Medicare Advantage plan is ending?
Check for a nonrenewal notice, which lists the end date and your options. Then verify in Medicare.gov or Plan Finder. If nothing arrives or it's unclear, call your insurer or Medicare.
Can I switch to Original Medicare if my Medicare Advantage plan ends?
Yes. A qualifying termination creates a Special Enrollment Period. Part D and any Medigap policy are separate decisions with their own deadlines.
Can I get Medigap after losing Medicare Advantage?
Often, yes. Many people get guaranteed-issue rights, but eligibility, available policies, state rules, and the 63-day window apply. Act promptly and keep your notice.
