Misled by a Medicare Agent or Plan? The Special Enrollment Periods That Let You Leave

If a Medicare agent, broker, or plan representative told you something that turned out to be wrong — a doctor was "in network" when she wasn't, a drug was "covered" when it isn't, or extra benefits were promised that don't actually exist — you are not stuck in the plan. Federal rules give you more than one Special Enrollment Period (SEP) to leave, and in some cases a guaranteed right to buy a Medigap policy. Here is how those protections work, in plain English.

The "misleading information" SEP (case-by-case)

Medicare.gov lists joining a plan based on misleading or incorrect information from a plan representative among the "other exceptional circumstances" that may qualify you for a Special Enrollment Period. These requests are reviewed case by case. If Medicare agrees you qualify, you have 2 months to act — and during that window you can:

• Switch to another Medicare Advantage Plan or another Medicare drug plan,
• Drop a Medicare Advantage Plan and return to Original Medicare, or
• Drop your Medicare drug coverage.

To start the process, call 1-800-MEDICARE and describe what you were told, by whom, and how it differed from the plan's actual rules. Keep any emails, enrollment paperwork, call notes, or marketing materials you still have — they help.

The contract-violation SEP (CMS must approve)

There is a second, distinct SEP that CMS's enrollment guidance calls the SEP for contract violations. It applies when a Medicare Advantage organization — or its agent, representative, or a plan provider — materially misrepresented the plan's provisions in its communications, or when the organization substantially violated a material provision of its contract with you. A common example is failing to provide medically necessary covered services on a timely basis.

Three things to know about this SEP:

1. It requires CMS approval before you can use it. You must demonstrate the violation to CMS. 2. CMS guidance says you must call 1-800-MEDICARE to make your election using it. 3. After CMS determines a violation occurred, you can choose to be disenrolled immediately and returned to Original Medicare, or to join a new plan right away. If you don't choose immediately, you have 90 calendar days to make an election, and CMS may process a retroactive disenrollment on a case-by-case basis.

If a federal employee gave you bad information

A separate SEP exists for a narrower situation: you joined, or chose not to join, a Medicare Advantage plan with drug coverage or a stand-alone Medicare drug plan because of an error, misrepresentation, or inaction by a federal employee or someone authorized to act on behalf of the federal government. That SEP lasts 2 full months after the month you get a notice of the error from Medicare.

Your Medigap guaranteed-issue right

Leaving a Medicare Advantage plan is only half the picture if you want to return to Original Medicare. Many people also want a Medigap (Medicare Supplement) policy to help with out-of-pocket costs. According to the March 2026 edition of Medicare's "Choosing a Medigap Policy" guide, people who leave a Medicare Advantage Plan — or drop a Medigap policy — because the company hasn't followed the rules or misled them have a federal guaranteed-issue right to buy Medigap Plan A, B, D, or G sold by an insurance company in their state. (Plans C or F are options only if you were eligible for Medicare before January 1, 2020.) You must use this right no more than 63 days after your prior coverage ends, so don't wait.

Medicaid and Extra Help: a monthly SEP

If you have Medicaid or qualify for Extra Help with Part D costs, you have your own monthly SEP. Since 2025, you can use it once per month to move to Original Medicare paired with a stand-alone Part D plan, or to switch from one stand-alone Part D plan to another. If you are a full-benefit dual-eligible, you can also join an integrated D-SNP in any month. This is a separate protection from the "misled" SEPs above and doesn't require you to prove wrongdoing.

Comparing your options after you leave

If your SEP lets you choose between staying with Medicare Advantage (with a different plan) and returning to Original Medicare (often paired with a Part D plan and a Medigap policy), weigh the trade-offs:

• Medicare Advantage bundles Parts A, B, and usually D and may include extra benefits, but typically uses provider networks and prior authorization and varies plan by plan.
• Original Medicare + Part D + Medigap lets you see any provider who accepts Medicare nationwide and makes costs more predictable through Medigap, but you pay separate premiums and most Medigap plans don't include drug, dental, vision, or hearing coverage.

Neither option is "better" in the abstract — the right answer depends on your doctors, your medications, your budget, and how you like to manage coverage.

A few 2027 program facts to keep in mind

As you compare plans, these national Part D numbers apply in 2027: the out-of-pocket cap is $2,400 (up from $2,100 in 2026), the highest deductible a Part D plan may charge is $700, and the Part D base beneficiary premium — used to calculate any late-enrollment penalty — is $41.33. Actual plan premiums are set plan by plan.

The Annual Enrollment Period for 2027 coverage runs October 15 – December 7, 2026, with choices taking effect January 1, 2027. The Social Security Administration announced a 3.6% COLA for benefits payable beginning January 2027. The 2027 Part B standard premium and deductible, along with the IRMAA income brackets, had not been released at the time of writing; CMS typically announces them in the fall.

Where can you get help with Medicare questions?

If you think you were misled when choosing a Medicare plan, call 1-800-MEDICARE (1-800-633-4227; TTY 1-877-486-2048), available 24 hours a day, 7 days a week except some federal holidays. You can also learn more at Medicare.gov, and report suspected fraud or marketing abuse through the Senior Medicare Patrol (SMP). Acting quickly matters — many of these SEPs have short windows, and the Medigap guaranteed-issue clock runs just 63 days.
