Medicare is a government-run health insurance program that mainly serves people who are 65 or older. Though it also covers younger people with qualifying disabilities or specific medical conditions.
If you’re caring for a family member who’s approaching their 65th birthday, it’s important to know that they must sign up for Medicare during a specific window known as the Initial Enrollment Period (IEP). This seven-month period starts three months before the month they turn 65 and ends three months after that month. Missing this window means waiting until the next General Enrollment Period (GEP), which runs from January 1 to March 31 each year. It can also lead to costly penalties. We’ll explain those details a bit later in this article.
Medicare also requires that the applicant is a U.S. citizen, or a lawful permanent resident who has lived in the U.S. continuously for at least five years prior to applying.
How to Apply for Medicare in Arizona
Depending on the enrollee’s situation, the Medicare enrollment process is either automatic or manual.
Automatic Medicare Enrollment: What to Expect
If you care for someone who has been receiving Social Security retirement benefits for at least four months before turning 65, they’ll be automatically signed up for both Medicare Part A (hospital insurance) and Part B (medical insurance) when they reach their 65th birthday. In this case, there’s no need to take any action. Medicare will mail a welcome package and their new Medicare card about three months before coverage begins. Or they may receive their card during the 25th month of their Social Security Disability Insurance (SSDI) benefits.
For those who haven’t started Social Security benefits at least four months before turning 65, enrolling in Medicare isn’t automatic. They’ll need to actively apply during their Initial Enrollment Period, (IEP).
If your loved one is still working at 65 and has health coverage through their employer or their spouse’s employer, they may be able to delay Medicare enrollment without penalty. When they eventually retire or lose employer coverage, they can sign up for Medicare during a Special Enrollment Period, avoiding late fees.
Manual Medicare Enrollment: What to Expect
Enrolling in Medicare manually is a straightforward process. Here’s a clear breakdown to guide you through each step:
- Gather the necessary documents
- proof of your name
- Proof of date of birth
- Social Security number
- Evidence of U.S. citizenship or lawful residency
- Decide how you want to apply.
- Apply online at the Social Security Administration’s website
- Call 1-800-772-1213 (TTY: 1-800-325-0778)
- Visit your local Social Security office in person
- Choose the Medicare coverage that fits your needs (details will follow).
- Original Medicare (Part A and Part B)
- A Medicare Advantage plan (Part C)
- Optional prescription drug coverage (Part D)
- Optional Medicare Supplement (Medigap) policy
- Submit your application along with any required documentation.
- After applying, review the enrollment confirmation that Social Security sends you.
Once approved, a Medicare card should arrive by mail within 2–4 weeks, though the full approval process can take up to 6–8 weeks in some cases.
Important Note for all Medicare Enrollees
If the person you care for has employer-sponsored health coverage that includes a Health Savings Account (HSA), once they enroll in any part of Medicare, they can no longer contribute to their HSA. Many people with HSAs choose to delay both Part A and Part B to keep making HSA contributions while they’re still working and covered by their employer’s plan.
Late Enrollment Penalties
Let’s say the person you care for doesn't sign up for Medicare during the IEP, and they don't qualify for a Special Enrollment Period (SEP). What happens? They may have to pay late enrollment penalties when they eventually enroll. And the fines get higher the longer they wait. Some fines will be charged monthly for as long as they’re covered. So whatever you do, don’t let them miss the IEP.
The Many Parts of Medicare, Explained

For a lot of people choosing from the many Medicare coverage options can be one of the most overwhelming challenges of enrolling in Medicare. Generally, there are two options: Original Medicare (Parts A and B) and Medicare Advantage (Part C). In Arizona, a little over half of Medicare enrollees choose Original Medicare over Medicare Advantage. Nationwide, it’s pretty evenly split.
Let’s break down both options.
Original Medicare
If the person you care for chooses Original Medicare, they’ll pay for services as they receive them. That’s why sometimes you hear people call it Fee For Service Medicare. Your loved one would pay a deductible and usually a 20% coinsurance for Medicare-approved services. About 99% of all healthcare providers accept Medicare. And your loved one can choose to see any of them without needing a referral.
Original Medicare is divided into two main parts, Part A and Part B. Each part covers different types of health care expenses.
Your loved one can also purchase prescription drug coverage (Part D). And they can buy supplemental coverage (a Medigap policy, Parts F-N) that covers many of the costs that Medicare Parts A and B don’t.
Medicare Part A (Hospital Insurance)
What Part A covers:
- inpatient hospital costs
- care provided in skilled nursing facilities
- hospice care
- home health care required after discharge from a hospital or skilled nursing facility
Note: There is no out-of-pocket maximum for Part A. So the amount your loved one could spend on these types of healthcare costs is unlimited.
Medicare Part B (Medical Insurance)
What Part B covers:
- certain doctors' services
- outpatient care
- durable medical equipment
- preventive services
- home health services for enrollees who meet eligibility criteria*
Note: Part B also has no out-of-pocket maximum.
*To learn if the person you care for qualifies for home health services covered by Medicare, and if you qualify to get trained, certified, and hired as a paid member of their home health team, take the RubyWell quiz.
Medicare Part D (Prescription Drug Coverage)
What Part D covers:
- a portion of the cost of prescription drugs
- many recommended vaccines
Medicare Plans F, G, and K-N (Medicare Supplement Insurance or Medigap)
What Medigap Plans cover:
- your loved one’s share of out-of-pocket costs in Original Medicare, including
- deductibles
- coinsurance
The different Medigap plan letters refer to different levels or amounts of coverage. Medigap plans can “underwrite.” That means if your loved one has pre-existing health conditions, the plan can charge them more. The only time Medigap plans can’t underwrite is when the enrollee first becomes eligible to apply for Medicare (during the IEP).
Medicare Advantage (Medicare Part C)
These Medicare-approved plans are offered by private companies. They must include all of the Part A and Part B benefits. Many usually include Part D coverage as well as many “supplemental benefits” that aren’t covered by Original Medicare. These can include:
- vision
- hearing
- dental
- gym memberships
- prepaid Over-the-counter debit cards
- and more
Medicare Advantage (MA) plans can’t “underwrite.” So pre-existing health conditions aren’t considered when determining cost.
Most MA plans operate like an HMO or PPO. When your loved one chooses from a network of approved health care providers, they receive the maximum benefit amount. And if they need to see a specialist, they’ll need a referral from their primary care physician in order for the visit to be covered.
With an MA PPO, they can see a provider outside the network, but they’ll pay a higher copay. And in many cases, they won’t need a referral or prior authorization to see a specialist.
If the person you care for chooses an MA plan, they cannot add a Medigap plan to their coverage.
Which Arizonans are Eligible for Medicare?

- They must meet age, disability, or medical condition requirements.
Age Requirement
Arizonans who are at least 65 years old are eligible for Medicare.

Some Arizonans may qualify for Medicare before they turn 65. They must have received Social Security Disability Insurance (SSDI) payments or Railroad Retirement Board disability benefits for at least 24 months.
Medical Condition Requirement
Arizonans can qualify for Medicare before age 65 if they have been diagnosed with either of these diseases:
- End-Stage Renal Disease (ESRD)

What Does Medicare Cost in AZ?
Medicate reviews and updates their premium and deductible costs for Medicare every year. You can find the most current information on the Medicare costs page at Medicare.gov.
Part A Medicare Costs
Monthly Premium
Good news: The Part A monthly premium is $0 if your loved one or their spouse paid Medicare taxes while working for a certain period. And free is good!
If they aren’t eligible for this premium-free Part A, they can purchase Part A for a monthly premium that can range from $278 to $505 (in 2025). The cost depends on how long they or their spouse worked and paid Medicare taxes.
Deductible
The Part A deductible is $1,676 per benefit period in 2025.
What is a benefit period? It begins the day your loved one is admitted to a hospital or skilled nursing facility. And it continues throughout their stay, and includes any subsequent stays as long as they don’t go more than 60 consecutive days without inpatient care.
Coinsurance
Your loved one will also have to pay any coinsurance related to their hospital or skilled nursing care.
Part B Medicare Costs
Monthly Premium
Everyone pays a monthly premium for Part B. In 2025, that premium is $185.
Deductible
The annual deductible in 2025 is $257.
Coinsurance
After they meet their deductible, the person you care for will be responsible for 20% coinsurance payments for any Part B services they receive.
Part D Medicare Costs
Monthly Premium
Every Medicare Prescription Drug plan (Part D) charges a monthly premium. The premiums vary. In 2024, they averaged approximately $55.50.
Deductible
Also varying by plan, Part D plan deductibles were no more than $545/year in 2024.
Recent Protection
As of January 1, 2025, Medicare beneficiaries don’t pay more than $2,000 for prescription drugs during a given plan year. We all can thank the 2022 Inflation Reduction Act for that.
Medigap (Parts F-N) Costs
Monthly Premium
Private insurance companies sell Medigap policies with costs that vary widely based on coverage and insurance provider. In 2023, the average monthly premium for Medigap policies was $186.49. It’s wise to speak with several insurance providers in your area to understand pricing options available.
Medicare Advantage (Part C) Costs
Monthly Premium
If the person you care for chooses a MA plan, they’ll still pay the Medicare Part B premium ($185/month). And if they don’t qualify for premium-free Part A, they’ll have to pay for Part A, too ($278 to $505).
Additionally, they may have to pay a Part C monthly premium, depending on the MA plan. Premium amounts can vary widely since MA plans are offered by private insurance companies and may provide different supplemental benefits. The average monthly plan premium for all MA plans was $18.50 in 2024. Some Medicare Advantage plans started offering reductions in the Medicare Part B premium in 2025.

Advice from a Medicare Expert
Still feeling overwhelmed by all of the Medicare choices? You’re not alone. Luckily there are professionals who can help people sort through all the options. One of them is Gustavius Smith. He’s CEO of Rxcare.ai, a technology company that’s simplifying Medicare for beneficiaries and brokers.
He says, “Choose the plan that’s right for you.” His best advice for selecting Medicare coverage? “Start by asking a friend for the name of a trusted Medicare broker. However, this should be the last time you rely on friends, relatives, or acquaintances for Medicare advice.”
Alternatively, Smith suggests attending a Medicare educational seminar hosted by a licensed broker in your area. There you should receive unbiased information. And you can ask questions in a no-pressure setting. You can confirm what you learn in the seminar with the Medicare & You handbook provided by CMS.
“Then, create a Medicare.gov account and schedule a one-on-one session—either in person or online—with the broker you met at the seminar,” adds Smith. “This broker will guide you in selecting the best Medicare coverage for your needs. And they won’t charge you for this service.”
