Medicare Supplement plans can help Arizonans pay for out-of-pocket Medicare costs.

What You Need to Know

A Medicare Supplement plan can help pay healthcare expenses that Original Medicare doesn’t cover. 

To qualify for a Medigap policy, you need to be enrolled in Medicare Part A and B. 

You can choose from 12 Medigap policies in Arizona, including two high-deductible options. 

Medicare Supplement plans can help Arizonans pay for out-of-pocket Medicare costs.

While Original Medicare (Medicare Part A, for hospital services, and Part B, for outpatient services) covers many healthcare expenses, it still leaves you responsible for some out-of-pocket costs. Expenses like copayments and deductibles can quickly add up, especially if you have frequent healthcare needs. 

A Medigap policy, also called a Medicare Supplement plan, is additional coverage from a private insurer that helps reduce or eliminate some of the out-of-pocket expenses that Original Medicare doesn’t cover. 

When Can You Enroll in Medigap in Arizona? 

You can enroll in Medicare Supplement Insurance in Arizona during your Medigap Open Enrollment Period (OEP).1 It is a six-month period that automatically starts the month that you turn 65 and are enrolled in Medicare Part B. During your Medigap Open Enrollment Period, you can buy any Medicare Supplement plan, and an insurance provider can’t charge you more or deny you coverage for a preexisting condition like COPD. If you decide that the plan you choose isn’t right for you, you can change it during your enrollment period. 

Once your Medigap Open Enrollment Period ends, enrolling in Medigap becomes more difficult. An insurance provider can charge you a higher premium or reject you because of your preexisting condition. The provider might also require a six-month waiting period before your plan’s coverage goes into effect.

In certain situations, you can qualify for protections that help you sign up for Medigap outside open enrollment. You have a guaranteed issue right if your current healthcare changes, for instance, if your current plan leaves Medicare.2 With a guaranteed issue right, an insurance provider can’t charge you a higher premium. 

There are other situations, like moving or losing your current coverage, that qualify you for a Special Enrollment Period.3 During this period, you’ll be able to make changes to your policy, depending on the type of qualifying event you experienced.  

When First Eligible

If you sign up for a Medicare Supplement plan when you’re first eligible, you can’t be charged a higher rate because of a health condition.

More than 340,000 Arizonans chose Medigap policies to augment their Medicare coverage in 2019 (the year with the most recent data). More than nine out of 10 chose to go with Plan F, G, or N.4

In Arizona, you can choose from 10 Medicare Supplement Insurance plans and two high-deductible options. Each lettered plan is the same across different insurers. Plan premiums, deductibles, copayments, and coverage vary, so it’s important to carefully review each plan to decide which one is right for you.

How Do You Choose a Medicare Supplement Plan in Arizona?

To get the most value out of your Medigap policy in Arizona, you’ll want to choose a plan that covers the types of healthcare expenses you face most often.

You might find that a plan with a higher premium actually gives you better value, because it saves you money on your most common healthcare costs.

When choosing your Medicare Supplement plan, look for a plan that balances the coverage you need with a premium that you can afford. Medigap plans don’t offer prescription drug coverage. So if you need options look into Medicare Part D plans.

If you choose the right plan for your needs during your Open Enrollment Period, you won’t have to worry about changing it later on.
