Medicare Annual Enrollment Period 2026: What Arizona Seniors Should Do Before October 15
Every fall, Medicare’s Annual Enrollment Period (AEP) gives you a window to make changes to your coverage for the year ahead. This year, that window runs from October 15 through December 7, 2026. Any changes you make take effect January 1, 2027. Here’s what the Medicare Annual Enrollment Period Arizona season means for you this fall.
If you’re one of the many Medicare beneficiaries here in the West Valley — Surprise, Sun City, Sun City West, Peoria, and the surrounding communities — this is worth a spot on your calendar even if you’re happy with your current plan. Here’s why, and what you can actually do during this period.
What You Can Change During the Medicare Annual Enrollment Period Arizona
During the Annual Enrollment Period, you can switch from Original Medicare to a Medicare Advantage plan, or vice versa; move from one Medicare Advantage plan to another; change your Medicare Part D prescription drug plan; or enroll in a Part D plan for the first time if you didn’t sign up when you were first eligible (late enrollment penalties may apply).
One thing AEP does not cover: Medigap (Medicare Supplement) plans. Those have their own enrollment rules and typically require medical underwriting outside of your initial enrollment window.
Why review your plan even if nothing feels “wrong”
Plans change every year — provider networks, drug formularies, premiums, and extra benefits can all shift from one year to the next, even if you don’t touch a thing. A plan that was the best fit for you last January isn’t guaranteed to still be the best fit this January. A quick annual review is the only way to know for sure.
What working with an independent broker looks like
As an independent broker, I’m not tied to a single insurance company, which means the goal of our conversation is finding what actually fits your situation — not steering you toward one carrier’s product. A brief intake call to understand your current coverage, doctors, and prescriptions. Independent research across multiple carriers on your behalf. A clear, comprehensive quote emailed to you — no pressure, no obligation. You decide when (or whether) you’re ready to move forward, at your own pace.
