Medicare Annual Enrollment Period in Arizona: Dates You Need to Know

If you have Medicare in Arizona, it’s important to mark your calendar for the Annual Enrollment Period, or AEP. This period runs from October 15 to December 7 each year. During this time, you can review your current Medicare coverage and make changes that will take effect on January 1 of the next year.

Whether you have Original Medicare (Part A and Part B) or a Medicare Advantage plan, AEP is your chance to update your coverage to better fit your needs.

What You Can Change During AEP in Arizona

During the AEP, Arizona seniors have several options to adjust their Medicare plans:

Arizona has a wide variety of Medicare Advantage plans, many of which include extra benefits like dental, vision, and hearing coverage that Original Medicare does not cover. This means reviewing your plan options during AEP could lead to better benefits and potential savings.

Keep in Mind: Arizona-Specific Considerations

While many areas in Arizona offer multiple Medicare Advantage plan choices, some rural parts of the state have limited options. If you live outside of the larger cities like Phoenix or Tucson, be sure to check carefully that the plan you want has doctors and hospitals nearby. Provider availability can vary between plans, and having the right network is important.

Common Mistakes to Avoid During AEP

Many Arizona seniors miss out on the full benefits of AEP due to some common pitfalls. Here’s what to look out for:

How to Compare and Choose the Right Plan in Arizona

Before making any changes, take time to review your options. Arizona seniors can use the official Medicare Plan Finder tool online to compare plans in their area. Additionally, free help is available from the Arizona State Health Insurance Assistance Program (SHIP). You can find counselors through AzMedicare.gov or by contacting the Arizona Department of Insurance.

These resources can help you understand costs, coverage, and networks to make the best choice for your health needs and budget.

What Happens After December 7?

Once AEP ends on December 7, your Medicare coverage locks in for the next year unless you qualify for a Special Enrollment Period (SEP). Examples of SEPs include moving out of your plan’s service area or becoming eligible for Medicaid. It’s important to know if any of these changes apply to you, but otherwise, you’ll need to wait until next year’s AEP to make changes.
