Your first year on Medicare involves more than simply getting a Medicare card. Arizona seniors should expect to choose how they receive coverage, review prescription benefits, understand premiums and out-of-pocket costs, verify doctors and pharmacies, and learn important enrollment deadlines. Reviewing coverage early can help prevent unexpected expenses and coverage gaps.
- Start early: Your Initial Enrollment Period generally lasts 7 months—3 months before your 65th birthday month, your birthday month, and 3 months afterward.
- Understand your choices: You can generally receive Medicare through Original Medicare or choose a Medicare Advantage plan.
- Review prescriptions carefully: Drug coverage, formularies, pharmacy networks, deductibles, and cost-sharing can differ significantly between plans.
- Check your doctors: Confirm that your preferred physicians, specialists, hospitals, and pharmacies work with the plan you are considering.
- Know your Medigap window: If you choose Original Medicare, your one-time Medigap Open Enrollment Period generally lasts 6 months beginning when you are 65 or older and enrolled in Part B.
- Expect an annual review: Medicare coverage should be reassessed each year because premiums, benefits, provider networks, formularies, and personal healthcare needs can change.
- Don’t ignore paperwork: Save Explanation of Benefits statements, bills, notices, and correspondence so you can identify errors or resolve coverage questions.
What Happens When You First Enroll in Medicare?
Turning 65 is an important milestone, but Medicare enrollment is not a one-size-fits-all process.
Your first decision is determining when to enroll in Part A and Part B. For people approaching Medicare eligibility, the timing can depend on whether they are still working, have employer-sponsored coverage, have coverage through a spouse, or qualify for a Special Enrollment Period.
For most people, the Initial Enrollment Period lasts seven months. Missing the appropriate enrollment window can result in delayed coverage and, in some circumstances, late enrollment penalties.
This is one reason it is helpful to begin planning several months before turning 65 rather than waiting until your birthday month.
What to Review Before Your Medicare Coverage Starts
Create a simple Medicare checklist that includes:
- Your Medicare eligibility date
- Whether you are currently working
- Your current employer or spouse’s employer coverage
- Your doctors and specialists
- Your prescription medications
- Your preferred pharmacies
- Your anticipated healthcare needs
- Your monthly budget
- Your preferred type of coverage
- Important enrollment deadlines
This preparation can make the transition from employer coverage or another form of health insurance considerably easier.
Understanding Your Medicare Coverage Choices
One of the biggest decisions during your first year is deciding how you want to receive your Medicare benefits.
| Option | How it generally works | What to consider |
| Original Medicare + Medigap + Part D | Medicare Parts A and B cover eligible services; Medigap can help with certain out-of-pocket costs; Part D provides prescription coverage | Premiums, provider access, prescription costs, and Medigap availability |
| Medicare Advantage | A private Medicare-approved plan provides Part A and Part B benefits, usually through a plan network | Networks, copays, deductibles, referrals, drug coverage, and maximum out-of-pocket costs |
| Original Medicare alone | Uses Medicare Part A and Part B without supplemental coverage | You may have significant cost-sharing and no annual out-of-pocket maximum under Original Medicare alone |
Medigap policies are designed to help pay certain costs that Original Medicare does not fully cover. Importantly, Medigap is generally only available with Original Medicare, not Medicare Advantage.
Why Your First Six Months Matter
If you are 65 or older and have Part B, your Medigap Open Enrollment Period generally begins when Part B starts and lasts six months. During this period, you have important protections when purchasing a Medigap policy, including the ability to buy a policy sold in your state without medical underwriting for pre-existing health conditions.
Practical insight: Don’t treat the Medigap window as just another annual enrollment deadline. It is a one-time period, unlike Medicare’s yearly Open Enrollment Period.
Prescription Drug Coverage Is a Major Part of Your First Year
Prescription costs can be easy to underestimate.
A plan that looks inexpensive based on its monthly premium may not necessarily be the least expensive option once your medications are considered.
Before selecting coverage, create a current medication list containing:
- Prescription name
- Dosage
- Frequency
- Quantity
- Preferred pharmacy
- Generic or brand-name status
Then compare how each plan covers those medications.
Look beyond the premium and check:
- Drug formularies
- Deductibles
- Copayments
- Coinsurance
- Pharmacy networks
- Preferred pharmacies
- Coverage restrictions
- Prior authorization requirements
- Step therapy requirements
Your medication list should be reviewed whenever you compare Medicare plans—not just when you initially enroll.
What Medicare Costs Should You Expect?
Medicare costs depend on your coverage choices, income, healthcare usage, prescriptions, and plan.
For 2026, Medicare lists the standard Part B premium at $202.90 per month, although higher-income beneficiaries may pay more. The Part B deductible is $283 in 2026.
These figures illustrate an important point: the monthly premium is only one part of your healthcare budget.
Your actual expenses may also include:
- Deductibles
- Copayments
- Coinsurance
- Prescription costs
- Specialist visits
- Diagnostic testing
- Hospital services
- Dental, vision, or hearing expenses not covered by Original Medicare
- Premiums for supplemental or prescription coverage
When evaluating Medicare health insurance, calculate your potential annual cost, not simply your monthly premium.
Your Doctors and Specialists Matter
One of the most common concerns during the transition to Medicare is: “Can I keep my doctor?”
The answer depends on the coverage you select.
Before enrolling in a Medicare Advantage plan, verify the network status of:
- Primary care physician
- Cardiologist
- Orthopedist
- Oncologist
- Other specialists
- Preferred hospital
- Imaging centers
- Urgent care locations
- Preferred pharmacy
Network information can change, so verify the provider relationship using current plan information rather than relying exclusively on an old insurance card or a doctor’s website.
For someone managing multiple specialists, provider access can be just as important as the monthly premium.
What to Expect During Your First Year
Your first year is really a learning period.
Months 1–3: Get Organized
Focus on:
- Confirming your Medicare coverage
- Reviewing your plan documents
- Establishing your primary care relationship
- Confirming prescriptions
- Understanding your deductible and copays
- Creating an account with your insurer when appropriate
Months 4–6: Watch Your Actual Costs
Compare your expectations with what you are actually paying.
Keep track of:
- Doctor visit costs
- Prescription expenses
- Lab and imaging bills
- Specialist costs
- Unexpected charges
- Claims and Explanation of Benefits statements
This creates a useful baseline for next year’s plan comparison.
Months 7–12: Prepare for Your Next Review
As you approach the end of your first year, review your Annual Notice of Change and compare your current plan with available alternatives.
Medicare’s annual Open Enrollment Period runs October 15 through December 7, with changes generally becoming effective January 1.
Don’t automatically renew simply because your current plan worked well during your first year.
Medicare Advantage vs. Medicare Supplement: Which Is Better?
There is no universally “best” choice.
The right option depends on your healthcare preferences, budget, doctors, prescriptions, travel habits, and tolerance for different types of cost-sharing.
Medicare Advantage may appeal to people who:
- Want an all-in-one plan
- Prefer predictable copays for certain services
- Want additional plan benefits
- Are comfortable using provider networks
- Want prescription coverage included in many plans
Original Medicare + Medigap may appeal to people who:
- Value broad provider access
- Want supplemental coverage for certain Medicare cost-sharing
- Prefer Original Medicare
- Want to evaluate a separate Part D prescription plan
- Are comfortable paying premiums for supplemental coverage
The key is to compare the total coverage and potential costs, rather than choosing solely on premium price.
A Simple First-Year Medicare Checklist
Use this checklist before and after enrollment:
Before enrollment
- Confirm your Medicare eligibility date
- Review employer coverage
- Make a medication list
- List your doctors and specialists
- Compare Medicare Advantage and Original Medicare options
- Investigate Medigap and Part D if appropriate
- Review estimated annual healthcare costs
After enrollment
- Confirm your coverage effective date
- Verify provider participation
- Confirm prescription coverage
- Learn how claims and bills work
- Save important Medicare documents
- Monitor healthcare spending
- Review your plan before the next enrollment period
Don’t Wait Until There Is a Problem
Medicare questions are often easier to solve before they become billing or coverage problems.
If you receive a confusing bill, denied claim, unexpected prescription cost, or prior authorization request, don’t assume you have to figure it out alone. Review the explanation, contact the appropriate insurer or Medicare resource, and keep documentation of your communications.
For families helping an aging parent, keeping a shared folder—digital or physical—with Medicare cards, plan documents, medication lists, provider information, and important correspondence can make future questions much easier to manage.
