How do I cancel a Medicare Advantage plan?

During a valid window — the fall Annual Enrollment Period (Oct 15 – Dec 7) or the MA Open Enrollment Period (Jan 1 – Mar 31 if you're already in an Advantage plan) — either enroll in a new plan (which auto-cancels the old one) or return to Original Medicare. If you return to Original Medicare, add a stand-alone Part D plan in the same window to avoid drug-coverage penalties, and check Medigap underwriting before assuming you can add a supplement.

Can I drop my Medigap plan anytime?

Yes — Medigap isn't tied to the enrollment calendar and cancels with a call to the carrier. The trap is the return trip: outside your original 6-month window, getting a Medigap policy again usually means medical underwriting, and carriers can decline or surcharge you. Treat dropping Medigap as potentially permanent.

Can I cancel Medicare Part B?

You can, through Social Security, and it's usually a mistake unless you have current employer coverage from active employment. Without that, you'd be uninsured for most outpatient care, and re-enrolling later means waiting for an enrollment period plus a lifelong 10%-per-12-months late penalty. Talk to Social Security — and ideally SHIP or an agent — before signing form CMS-1763.

What happens if I cancel a drug plan and don't replace it?

Every month without creditable drug coverage adds about 1% of the national base premium to your future Part D premiums — permanently. If your plan year didn't include a drug plan by design (for example, drug coverage through the VA), that coverage counts as creditable; going bare does not.

Canceling a Medicare plan without hurting yourself

"How do I cancel my Medicare" almost never means one thing. Leaving an Advantage plan, dropping a drug plan, ending a Medigap policy, and quitting Part B itself are four different moves with four different consequence profiles — one of them routine, one of them a one-way door, one of them a quiet penalty machine. Match your situation below before you sign anything.

Which cancellation are you actually doing?

Leaving an Advantage plan → another Advantage plan

The routine one. In AEP (Oct 15 – Dec 7) or MA-OEP (Jan 1 – Mar 31), enrolling in the new plan cancels the old one automatically — no cancellation call needed, no gap. Run the doctor carry-over check on the new plan first; that's the whole risk.

Leaving Advantage → back to Original Medicare

Allowed in the same windows — but it's a two-part move, and people do half of it. Part two: a stand-alone Part D plan in the same window (skipping it starts the ~1%/month penalty), and if you want a Medigap supplement, check underwriting before you leap — outside your original window and outside trial rights, carriers in most states can say no. Confirm the Medigap approval first, then cancel.

Dropping a Medigap policy

Anytime, one call to the carrier. But treat it as potentially permanent: re-entry later usually means underwriting, and the moment you most want back in tends to be the moment your health file argues against you. Shopping premium? Compare via G vs. N and apply for the new policy first — cancel the old one only after approval.

Dropping Part B itself

The one that's usually a mistake. Legit mainly when you (or your spouse) return to active employment with group coverage — otherwise you're uninsured for most outpatient care and the 10%-per-12-months penalty compounds against your future self. Social Security requires its own process (form CMS-1763 and a conversation) precisely because people regret this one. Talk to SSA at 1‑800‑772‑1213, and get a second opinion from SHIP or an agent first.

Wanting out usually means something's misfitting

Tell me what's driving the exit — cost, network, denials — and I'll tell you which move fixes it, which window it needs, and what to verify before you commit. Sometimes the answer is a better plan; sometimes it's "stay put." Both are on the menu.
