- You’re 65 years or older and a U.S. citizen or legal resident who has lived in the country for at least five consecutive years
- You’re under 65 with a qualifying disability and have received Social Security Disability Insurance (SSDI) for 24 months

The Four Parts of Medicare Explained
Medicare Part A (Hospital Insurance)
Medicare Part A covers inpatient hospital stays, skilled nursing facility care, hospice care, and some home health services. Most people receive Part A premium-free if they or their spouse paid Medicare taxes while working. However, you’ll still pay deductibles and coinsurance for covered services.
Medicare Part B (Medical Insurance)
Medicare Part B covers outpatient medical services, including doctor visits, preventive care, medical equipment, and some home health services. Unlike Part A, Part B requires a monthly premium that varies based on your income level. Standard monthly premiums for 2024 start at $174.70.
Medicare Part C (Medicare Advantage)
Medicare Advantage plans are private insurance alternatives that combine Parts A and B coverage, often including prescription drug coverage (Part D) and additional benefits like dental, vision, or wellness programs. These plans may have different costs and coverage rules than Original Medicare.
Medicare Part D (Prescription Drug Coverage)
Part D provides prescription drug coverage through private insurance companies. You can add Part D to Original Medicare or choose a Medicare Advantage plan that includes drug coverage. Monthly premiums vary by plan and income level.
When and How to Enroll
Initial Enrollment Period
Your Initial Enrollment Period begins three months before your 65th birthday month and extends three months after. During this seven-month window, you can enroll in Medicare Parts A and B without penalty.
Special Enrollment Periods
If you have qualifying employer coverage when you turn 65, you may be eligible for a Special Enrollment Period that allows you to delay Medicare enrollment without penalties. This period typically lasts eight months after your employer coverage ends.
Annual Open Enrollment
From October 15 to December 7 each year, you can make changes to your Medicare coverage, including switching between Original Medicare and Medicare Advantage plans or changing prescription drug plans.

Frequently Asked Questions
What happens if I miss my Initial Enrollment Period?
If you miss your Initial Enrollment Period and don’t have qualifying employer coverage, you may face late enrollment penalties. For Part B, the penalty is 10% of the standard premium for each 12-month period you were eligible but didn’t enroll. Part D penalties are calculated differently but can also result in permanently higher premiums.
Can I keep my current doctor with Medicare?
Whether you can keep your current doctor depends on your Medicare plan choice. With Original Medicare (Parts A and B), you can see any doctor who accepts Medicare. With Medicare Advantage plans, you’ll typically need to use doctors within the plan’s network, though emergency care is covered anywhere.
How much does Medicare cost?
Medicare costs vary based on the parts you choose and your income level. Part A is premium-free for most people, while Part B has standard monthly premiums starting at $174.70 in 2024. Medicare Advantage and Part D plan costs vary by provider and coverage level, with some plans having $0 monthly premiums but different deductibles and copayments.
