Who Can Get Medicare and When?
If you’re nearing retirement age or planning your healthcare future, understanding Medicare eligibility rules can save you from confusion down the road. Let’s make it simple and clear.
Are You Eligible for Medicare?
Medicare eligibility isn’t complicated once you understand the basics. Generally, you qualify if:
-
You’re 65 years old or older.
-
You’re under 65 but have certain disabilities or specific conditions such as End-Stage Renal Disease (ESRD) or Amyotrophic Lateral Sclerosis (ALS).
Most people enroll in Medicare around their 65th birthday, which kicks off your Initial Enrollment Period (IEP), lasting seven months—three months before your birthday, your birthday month, and three months after.
Medicare Enrollment Periods You Shouldn’t Miss
Understanding Medicare enrollment periods ensures you avoid late enrollment penalties.
Initial Enrollment Period (IEP)
Your IEP is a seven-month window around your 65th birthday:
-
Starts three months before your 65th birthday
-
Includes your birthday month
-
Ends three months after your birthday month
Enroll during your IEP to secure coverage without penalties.
General Enrollment Period (GEP)
If you miss your IEP, you can enroll during the GEP, which runs from January 1 through March 31 each year. Coverage begins on July 1, but penalties may apply.
Special Enrollment Period (SEP)
SEPs provide additional chances to enroll based on certain life events like losing employer coverage, relocating, or other qualifying situations. These periods typically last eight months following the triggering event.
Annual Enrollment Period (AEP)
AEP runs from October 15 to December 7 each year, allowing you to change your current Medicare plans for the upcoming year. New coverage begins January 1.
Understanding the Parts of Medicare and Their Costs
Medicare consists of different parts, each with unique costs, coverages, and conditions. Here’s a breakdown of what you should know for 2025:
Medicare Part A (Hospital Insurance)
Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice, and some home healthcare.
-
Premiums: Most people don’t pay a premium because they or their spouse paid Medicare taxes for at least 40 quarters (about 10 years). If not, the premium is $518 per month if fewer than 30 quarters and $284 per month for 30-39 quarters.
-
Deductible: The hospital inpatient deductible is $1,676 per benefit period in 2025.
-
Coinsurance: You’ll pay $419/day for days 61-90 of hospitalization and $838/day for days 91 and beyond (lifetime reserve days). Skilled nursing facility stays incur $209.50/day for days 21-100.
Medicare Part B (Medical Insurance)
Part B covers outpatient care, doctor visits, preventive services, and durable medical equipment.
-
Premium: The standard monthly premium is $185 in 2025.
-
Deductible: The deductible for Part B is $257 per year.
Remember, higher-income earners pay additional premiums known as Income-Related Monthly Adjustment Amounts (IRMAA).
Medicare Part D (Prescription Drug Coverage)
Medicare Part D covers prescription drugs. Significant changes for 2025 include:
-
A maximum deductible of $590.
-
A $2,000 annual cap on out-of-pocket drug costs, protecting you from excessive medication expenses.
You can also spread prescription drug costs evenly through monthly installments with the new Medicare Prescription Payment Plan option.
What about Medicare Advantage (Part C)?
Medicare Advantage plans (Part C) bundle coverage from Parts A, B, and usually D, and may include additional benefits like dental, vision, and hearing. In 2025, premiums are expected to remain stable or slightly decrease, although specific benefits can vary significantly by plan and region.
Avoiding Common Medicare Enrollment Mistakes
To maximize your Medicare benefits, watch out for these common pitfalls:
-
Missing Enrollment Deadlines: Missing your Initial Enrollment Period can result in lifelong late enrollment penalties, particularly for Part B, which increases premiums by 10% for each 12-month period delayed.
-
Assuming Automatic Enrollment: Automatic enrollment typically only applies to those receiving Social Security or Railroad Retirement Board benefits at least four months before turning 65. Otherwise, you must enroll manually.
-
Ignoring Medicare Part D: Delaying Part D enrollment without credible coverage can result in lifelong penalties of 1% per month for each month you were eligible but didn’t enroll.
Coordinating Medicare with Other Health Coverage
If you have employer or retiree health coverage, coordination is key:
-
Employer Coverage: If you work past 65 and have employer coverage from a job with more than 20 employees, you can delay enrolling in Parts B and D without penalty. Once you retire or lose this coverage, an 8-month SEP opens.
-
Retiree Coverage: Retiree health insurance often requires enrollment in Medicare Parts A and B. Review your employer’s rules to avoid losing coverage or incurring penalties.
-
COBRA and Medicare: COBRA is not considered creditable coverage for Medicare enrollment purposes. You have an 8-month SEP after employment coverage ends to enroll without penalty.
When Should You Consider Medicare Supplement (Medigap)?
Medicare supplement insurance, known as Medigap, helps cover out-of-pocket costs such as deductibles, coinsurance, and copayments. The best time to enroll in Medigap is during your Medigap Open Enrollment Period, lasting six months from your 65th birthday month, provided you’re enrolled in Part B. During this time, insurers cannot deny coverage or charge higher rates due to pre-existing conditions.
Reviewing Your Coverage Annually
Medicare coverage isn’t a “set it and forget it” system. Plans, benefits, and costs can change annually. During the Annual Enrollment Period (October 15–December 7), carefully review your coverage and make necessary adjustments effective January 1 of the following year.
Understanding Medicare Advantage Options
Medicare Advantage (Part C) plans can offer attractive benefits but also come with certain limitations, such as network restrictions and prior authorization requirements. It’s crucial to compare these details carefully each year and verify that your healthcare providers remain in-network.
Preparing for Cost Changes in Medicare
Each year, Medicare costs adjust slightly, impacting premiums, deductibles, and coinsurance. For example, Part B premiums rose to $185/month, and the Part A deductible increased to $1,676 for 2025. Preparing for these changes ensures you’re financially equipped and can budget appropriately.
Ensuring You Have the Right Medicare Coverage
Choosing the right Medicare coverage involves more than just costs. Evaluate your healthcare needs, including prescription drugs, doctor visits, specialist care, and hospital services, then select coverage accordingly.
Staying Informed about Medicare Updates
Medicare changes annually. Reviewing the Annual Notice of Change (ANOC), sent every September, helps you stay informed about updates to your plan’s coverage, premiums, and services, ensuring you’re not caught off guard.
