Medicare has several different enrollment periods throughout the year when you can make changes to your coverage. Each period serves a specific purpose and has different timeframes. The main enrollment periods include the Initial Enrollment Period, the General Enrollment Period, and various Special Enrollment Periods.

Your Initial Enrollment Period is a seven-month window that begins three months before the month you turn 65 and ends three months after. For example, if you turn 65 in June, your Initial Enrollment Period runs from March through September. This period is important because enrolling during this time helps you avoid potential late enrollment penalties that could increase your premiums for as long as you have Medicare coverage.
The General Enrollment Period occurs every year from January 1st through March 31st. During this time, anyone already enrolled in Medicare Part A or Part B can make certain changes to their coverage. However, changes made during the General Enrollment Period typically take effect on July 1st of that year, so there is a waiting period between when you make your selection and when coverage changes.
Special Enrollment Periods are available outside the standard timeframes if you experience qualifying life events. These events can include losing employer health coverage, moving to a new state, getting married or divorced, having a baby, or becoming a U.S. citizen. Each qualifying event has its own specific enrollment window, usually ranging from 30 to 60 days from when the event occurs. Understanding which enrollment periods apply to your situation helps you plan your Medicare decisions appropriately.
Practical Takeaway: Write down the dates that matter for your situation. If you are approaching 65, mark your Initial Enrollment Period on a calendar. If you already have Medicare, note that January through March is when you can make changes during the General Enrollment Period.

Practical Takeaway: Set aside time to visit Plan Finder and search for plans in your area, even if you do not plan to make changes immediately. Write down the names and plan types of several options available to you. Print or save the plan comparison worksheet and fill it out for plans you want to consider more seriously.
Medicare is divided into different parts, each covering different services. Learning about these parts helps you understand what information to look for when exploring your options online. Part A covers hospital services, including inpatient hospital stays, skilled nursing facility care, and some home health services. Part B covers outpatient medical services, including doctor visits, laboratory tests, and some medical equipment. Most people do not pay a premium for Part A if they or their spouse paid Medicare taxes while working, but Part B requires a monthly premium.

Original Medicare refers to the combination of Part A and Part B coverage managed directly by the federal government. When you have Original Medicare, you can see any doctor or hospital that accepts Medicare. You pay a deductible and then a percentage of costs for covered services. This approach gives you flexibility in choosing providers but means you share the cost of services through deductibles and coinsurance amounts. Online resources explain these cost-sharing amounts and how they work in detail.
Medicare Advantage, also called Part C, is an alternative to Original Medicare. With Medicare Advantage, you receive your Part A and Part B coverage through private insurance companies that contract with Medicare. These plans often include prescription drug coverage (Part D) in addition to medical coverage. Most Medicare Advantage plans have lower monthly premiums than Original Medicare plus separate Medigap coverage, but they typically limit you to using providers within their network. Online information explains these trade-offs in detail.
Part D prescription drug coverage helps pay for outpatient medications. You can obtain Part D coverage by enrolling in a standalone Part D plan if you have Original Medicare, or by choosing a Medicare Advantage plan that includes prescription drug coverage. Part D plans are offered by private insurance companies and vary in which medications they cover and what your costs are for different drugs. Online tools allow you to search which plans cover your specific medications in your area.
Medigap, or Medicare Supplement Insurance, is additional coverage available to people with Original Medicare. Medigap policies are offered by private insurance companies and help pay for costs that Original Medicare does not cover, such as deductibles and coinsurance. There are different Medigap plan types, labeled A through N, each
