Medicare enrollment in Arizona
As of late 2022, there were 1,434,539 residents with Medicare in Arizona, amounting to nearly 20% of the state’s population.
For most people, Medicare enrollment goes along with turning 65. But a disability that lasts at least two years also triggers Medicare eligibility, as does a diagnosis of kidney failure or ALS. In Arizona, nearly 10% of Medicare beneficiaries are under 65 — and enrolled due to a disability, kidney failure, or ALS — while about 90% are eligible due to their age. Nationwide, about 12% of all Medicare beneficiaries are eligible due to a disability, but there is some state-by-state fluctuation.

Original Medicare in Arizona
Original Medicare, which includes Medicare Part A (hospital coverage) and Medicare Part B (outpatient/medical coverage) is a federal program that does not vary from state to state. So overall Medicare eligibility in Arizona and Medicare enrollment in Arizona both work the same way they do in every state. For people who aren’t yet receiving Social Security benefits and thus aren’t automatically enrolled when they turn 65, the Medicare application in Arizona is available through the Social Security Administration, as is the case nationwide.
But the availability and pricing of private Medicare coverage, including Medicare Advantage plans, Medigap plans, and Medicare Part D plans, does vary from one state to another.

Medicare Advantage in Arizona
In most areas of the country, Medicare beneficiaries can choose whether they want to use Original Medicare (coverage provided directly by the federal government) or enroll in a private Medicare Advantage plan. Medicare Advantage plans cover all of the benefits provided by Medicare Parts A and B (although the out-of-pocket costs will differ, as will access to medical providers), and most also include Part D coverage for prescription drugs.
Medicare Advantage plans also tend to include extra benefits, such as dental and vision coverage, and care management programs that can help beneficiaries manage chronic conditions.
38 percent of Arizona Medicare beneficiaries had Medicare Advantage coverage as of 2018, compared with an average of 34 percent nationwide. Most of the rest of the state’s Medicare beneficiaries had coverage under Original Medicare, but there are also some enrollees in Arizona who have Medicare Cost plans.
Nationwide, enrollment in Medicare Advantage plans has been steadily increasing. Total enrollment in private Medicare plans, including Medicare Advantage and Medicare Cost plans, stood at 683,011 in Arizona as of late 2022, which was about 48% of the state’s total Medicare population (nationwide, about 46% of beneficiaries were enrolled in private plans at that point, with the rest in Original Medicare).
There are Medicare Advantage plans for sale statewide in Arizona for 2023, but plan availability varies considerably from one part of the state to another. In Navajo and Apache counties, there are 17 plans available, but residents in Maricopa County can select from among 93 different Medicare Advantage plans.
Medicare Advantage enrollment is available when a person is initially eligible for Medicare, and there’s also an annual enrollment window. Each fall, the Medicare annual election period, from October 15 to December 7, gives Medicare beneficiaries the option to switch between Medicare Advantage and Original Medicare. And people who are already enrolled in Medicare Advantage plans also have access to a Medicare Advantage open enrollment period (January 1 to March 31) during which they can switch to a new Medicare Advantage plan or drop their Medicare Advantage plan and enroll in Original Medicare instead.
Medigap in Arizona
Original Medicare beneficiaries who want help paying some or all of their out-of-pocket costs can purchase Medigap plans (also known as Medicare supplement plans). Medigap plans are issued by private insurers but are standardized under federal rules, with ten different plan designs (differentiated by letters, A through N). The standardization makes it fairly easy to compare plans – plans can differ in price and in things like customer service, but the benefits offered by Plan A, Plan C, Plan G, etc. are the same regardless of which insurer offers the coverage.
Unlike Medicare Advantage and Medicare Part D plans, there is no annual open enrollment period for Medigap plans. Instead, federal regulations allow for a six-month guaranteed-issue window that begins when a person is 65 and enrolled in Medicare Part B. After a person’s enrollment period ends (and unless the person qualifies for one of the limited guaranteed-issue rights), Medigap insurers can use medical underwriting to determine whether an applicant is eligible for coverage, and if so, at what price.
Federal rules do not grant a guaranteed issue open enrollment period for Medigap if the applicant is under 65 and enrolling in Medicare as a result of a disability. The majority of the states have implemented rules ensuring at least some access to Medigap plans for enrollees who are under the age of 65, but Arizona is not among them.
In 2009, the Arizona Department of Insurance announced that out of 53 insurers offering Medigap plans, five were offering coverage to disabled beneficiaries under the age of 65. But as of late 2022, there were 76 insurers licensed to sell Medigap plans in the state, and the AZ Department of Insurance list indicated that none of them were offering coverage to people under the age of 65. However, Medicare’s plan finder tool showed that one of these insurers — Guarantee Trust Life — does offer Medigap coverage (Plan A only) to people under age 65 in Arizona as of 2023, albeit at about five times the price that the insurer charges a person who is 65.
People under age 65 who have Medicare in Arizona do have the option to enroll in a Medicare Advantage plan (this includes beneficiaries with end-stage renal disease; prior to 2021, people with ESRD could not join most Medicare Advantage plans, but that is no longer the case). Medicare Advantage plans do not vary their premiums based on medical history, and they do have built-in out-of-pocket caps, so they may appeal to some disabled Medicare beneficiaries who would otherwise have Original Medicare without any caps on out-of-pocket costs. But there are pros and cons to Medicare Advantage, and enrollees should be aware of all of the details before selecting a plan.
Disabled Medicare beneficiaries qualify for a Medigap open enrollment period once they turn 65. At that point, they can enroll in any Medigap plan available in their area, without medical underwriting.
Medicare Part D in Arizona
Original Medicare does not cover prescription drugs. Some beneficiaries have employer-sponsored coverage to supplement their Medicare, and this often provides prescription coverage. But enrollees without this option need to obtain prescription coverage under Medicare Part D. Part D coverage can be purchased on its own, as a stand-alone plan, or as part of a Medicare Advantage plan that includes Part D prescription drug coverage. (Note that dual-eligibles, who are covered by both Medicare and Medicaid, receive their prescription coverage via Part D.)
For 2023, insurers in Arizona are offering 28 stand-alone Part D plan options with premiums ranging from about $5 to $166/month.
461,121 Arizona Medicare beneficiaries had stand-alone Part D plans as of late 2022, and another 649,219 had Part D coverage as part of their Medicare Advantage plans.
The annual Medicare open enrollment period (October 15 to December 7) is an opportunity for Medicare beneficiaries to change their Part D coverage if they choose to do so. Any changes made during this window will take effect on January 1 of the coming year. Beneficiaries are encouraged to compare all of the available plans each year, as the plan options may have changed since last year, as might have the enrollee’s prescription needs.
How does Medicaid provide financial assistance to Medicare beneficiaries in Arizona?
Many Medicare beneficiaries receive financial assistance through Medicaid with the cost of Medicare premiums, prescription drug expenses, and services not covered by Medicare – such as long-term care.
Our guide to financial assistance for Medicare enrollees in Arizona includes overviews of these benefits, including Medicare Savings Programs, long-term care coverage, and eligibility guidelines for assistance.
