Turning 65 is an exciting milestone, but Medicare enrollment can feel complicated. You may be comparing Part A, Part B, Medicare Advantage, Medigap, and Part D while trying to understand deadlines, premiums, provider networks, and prescription costs.
The good news is that you do not have to figure it out alone. This guide walks you through how to enroll in Medicare in 2026, what each coverage option does, and how to compare plans based on your health needs, lifestyle, and budget.

Step 1: Understand the Parts of Medicare
Before enrolling, learn what each part covers and how it affects your overall costs.
- Part A : Hospital Insurance: Covers inpatient hospital care, skilled nursing facility care in qualifying situations, hospice care, and some home health care. Most people pay a $0 monthly premium because they or a spouse paid Medicare taxes for approximately 10 years (40 quarters).
- Part B : Medical Insurance: Covers doctor visits, outpatient services, preventive care, durable medical equipment, and other medically necessary services. The standard 2026 Part B premium is $202.90 per month, and the annual Part B deductible is $283. Higher-income beneficiaries may pay more through an Income-Related Monthly Adjustment Amount (IRMAA).
- Part C : Medicare Advantage: Offered by private Medicare-approved insurers, Medicare Advantage plans combine Part A and Part B coverage and often include Part D prescription coverage. Many plans also offer dental, vision, hearing, fitness, or over-the-counter benefits.
- Part D : Prescription Drug Coverage: Helps pay for covered medications through a standalone drug plan or a Medicare Advantage plan that includes prescription coverage.
Original Medicare includes Parts A and B, but it does not have an annual out-of-pocket maximum by itself. You may add a Medigap policy, Part D plan, or other coverage to help manage expenses.
For official details, review Medicare’s explanation of the four parts of Medicare.
Your next step: Make a list of your doctors, prescriptions, preferred hospitals, and expected healthcare needs. Then request personalized Medicare guidance before comparing specific plans.
Step 2: Identify Your Medicare Enrollment Period
The enrollment period that applies to you determines when you can sign up and whether you may face a late enrollment penalty.
Initial Enrollment Period: Your First Opportunity
Your Initial Enrollment Period (IEP) lasts seven months:
- Three months before the month you turn 65
- The month you turn 65
- Three months after the month you turn 65
For example, if you turn 65 in June, your IEP generally runs from March 1 through September 30.
If you are already receiving Social Security retirement benefits at least four months before turning 65, you may be automatically enrolled in Part A and Part B. If not, you generally need to enroll through the Social Security Administration.
Enrolling during the three months before your birthday month generally gives you the best opportunity for coverage to begin when you turn 65. Waiting until your birthday month or later may delay your coverage start date.
General Enrollment Period: January 1 Through March 31
If you miss your IEP and do not qualify for a Special Enrollment Period, you can generally enroll in Part A and Part B during the General Enrollment Period (GEP), which occurs every year from January 1 through March 31.
Coverage usually begins the first day of the month after you enroll. However, delaying Medicare without qualifying employer coverage may result in a Part B late enrollment penalty. That penalty can increase your monthly premium for as long as you have Part B.
Special Enrollment Periods: When Life Circumstances Change
You may qualify for a Special Enrollment Period (SEP) if you had qualifying group health coverage based on current employment after becoming eligible for Medicare.
In many cases, you can enroll in Part B while you or your spouse continues working and has qualifying employer coverage. After the employment or coverage ends, you generally have an eight-month SEP to enroll in Part B without the standard late enrollment penalty.
You may need proof of employer coverage, such as:
COBRA, retiree coverage, and individual coverage may not provide the same protection as group health coverage based on current employment. Consequently, confirm your situation with Social Security before delaying Part B.
Other Medicare Advantage and Part D SEPs may apply if you move, lose other creditable coverage, qualify for Medicaid or Extra Help, or experience another qualifying life event. Review Medicare’s Special Enrollment Period information for the rules that apply to your circumstances.
Your next step: Write down your 65th birthday month, current employment status, and the date any employer coverage may end. Super Senior Services can help you organize your enrollment timeline.
Step 3: Enroll in Original Medicare Through Social Security
Medicare Advantage and Part D plans are offered by private insurers, but you generally enroll in Part A and Part B through Social Security.
You can:
- Apply online through SSA.gov Medicare.
- Call Social Security at 1-800-772-1213.
- Contact your local Social Security office.
Have your Social Security number, birth information, employment history, and current health coverage details available. If you are using an SEP based on employer coverage, allow time to gather the necessary forms.
Once you have confirmed your Part A and Part B effective dates, you can compare Medicare Advantage, Medigap, and Part D options.
Step 4: Compare Medicare Advantage, Medigap, and Part D
Medicare Advantage: Bundled Coverage and a Defined Maximum
Medicare Advantage plans combine Part A and Part B benefits and often include prescription drug coverage. Plans may use HMO, PPO, or Special Needs Plan structures.
When comparing a Medicare Advantage plan, review:
- Monthly plan premium in addition to the Part B premium
- Primary care and specialist copays
- Inpatient hospital costs
- Outpatient procedure coinsurance
- Referral and prior authorization requirements
- Provider and hospital networks
- Prescription formulary and pharmacy tiers
- Dental, vision, hearing, transportation, and other supplemental benefits
- Annual Part A and Part B maximum out-of-pocket limit
For 2026, CMS allows Medicare Advantage plans to set a maximum of up to $9,250 for in-network Part A and Part B services. Plans that cover out-of-network care may have a combined in-network and out-of-network limit of up to $13,900. Individual plans may set lower limits.
These maximums generally do not include Part D prescription expenses or many supplemental benefits. Read the plan’s Evidence of Coverage carefully.
Medigap: More Predictable Cost-Sharing With Original Medicare
Medicare Supplement, or Medigap, policies help pay certain deductibles, copayments, and coinsurance left by Original Medicare. Medigap plans are standardized by letter, so a Plan G from one insurer generally provides the same standardized benefits as Plan G from another insurer. Premiums, pricing methods, customer service, and availability can differ.
Your one-time Medigap Open Enrollment Period begins when you are at least 65 and enrolled in Part B. It lasts six months. During this window, you generally can buy any Medigap plan sold in your state without medical underwriting, meaning an insurer usually cannot deny coverage or charge more because of your health.
This is different from the annual Medicare Open Enrollment Period. The Medigap window does not automatically repeat each year.
Medigap policies generally do not include prescription coverage, so you would typically need a separate Part D plan. Compare premiums against the potential value of more predictable medical costs and broad access to Medicare-participating providers.
Read Medicare.gov’s Medigap guidance before applying.
Part D: Review Your Formulary Carefully
A formulary is the plan’s list of covered prescription drugs. Check every medication: not just the name, but also:
- Whether the drug is covered
- Which tier it occupies
- Whether you must use a preferred pharmacy
- Whether prior authorization or step therapy applies
- Whether quantity limits apply
- Whether a generic or lower-cost alternative is available
In 2026, covered Part D prescription drug costs are capped at $2,100 in annual out-of-pocket spending. After you reach the cap, you pay $0 for covered Part D drugs for the rest of the calendar year. The cap does not include your monthly plan premiums, and it applies only to covered medications under your plan’s formulary.
“If you have Medicare drug coverage (Part D), your yearly out-of-pocket Part D drug costs are capped at $2,100 in 2026.” : Medicare & You 2026
You can also ask whether the Medicare Prescription Payment Plan could help spread certain prescription expenses across the year. It does not reduce your total drug costs, but it may make monthly budgeting easier.
Your next step: Use the Medicare Plan Finder to review plan details, then have an experienced professional help you check the numbers against your actual doctors and medications.
Step 5: Compare Your Total Annual Cost: not Just the Premium
A low premium does not always mean a low-cost plan. To estimate your real expenses, compare:
- Monthly premiums (e.g., $0, $25, or $150 per month)
- Annual deductibles
- Doctor and specialist copays
- Hospital copays or coinsurance
- Outpatient treatment costs
- Prescription copays and coinsurance
- The plan’s maximum out-of-pocket limit
- Premium increases or expected changes
- Costs for services you use regularly
For example, a plan with a $0 monthly premium may charge higher copays for specialist visits or outpatient procedures. Another plan with a $75 monthly premium may offer lower cost-sharing and a stronger provider network. Your best option depends on how often you expect to use care.
Also confirm that your preferred doctors, hospitals, pharmacies, and specialists participate in the plan for 2026. Provider directories can change, and a familiar healthcare system is not automatically in-network for every plan.
