Medicare Enrollment: Your Comprehensive Guide 2020
Read our guide to understand when you should enroll and what the process entails.
Just as we covered in our Medicare Eligibility guide, you are eligible for Medicare once you turn 65. But simply being eligible may not necessarily take care of your enrollment.
There are still a few steps you will need to complete to receive your Medicare health insurance coverage.
Here, we will help you better understand the Medicare enrollment process, so that you are ready when the time comes.

How Do I Sign Up for Medicare?
Step 1: Sign Up Through Social Security
If you are already receiving benefits from Social Security then there is no further sign up required of you. You will receive your Medicare coverage automatically. 3 months prior to your 65th birthday, your Medicare card will come in the mail.
If you are not already receiving benefits from Social Security then your first step will be to sign up for Medicare through Social Security. You can do so online at the Social Security website.
Signing up online is likely your quickest and most convenience option. However, there are other sign up options available to you, as well. You can call Social Security at 1-800-772-1213, or you can find your local Social Security office to sign up in person.
The online process usually takes less than 10 minutes. You can sign up for both Part A and Part B with your online application. Once you submit your electronic application, Social Security will review and process your application. When this is complete, you will receive your Medicare card in the mail.
Step 2: Choose Your Medicare Coverage
The coverage you are signing up for through Social Security is Original Medicare. This consists of both Medicare Part A and Medicare Part B.
Medicare Part A
Part A is often referred to as hospital insurance. It covers a wide-range of inpatient and nursing facility care. Part A has no monthly premium, so it is free for eligible enrollees.
Part A Covers:
Skilled nursing facility care
Long-term care hospitals
Home health care
Medicare Part B
Part B is often referred to as medical insurance. It helps to pay for medical services and preventative treatment. Most people sign up for Part B at the same time they sign up for Part A. Parts A and B together form your Original Medicare coverage. However, because Part B requires you to pay a monthly premium, you are not required to sign up for it.
Part B Covers:
Medically Necessary Services
Medicare Part C (Medicare Advantage)
Medicare Part C, also known as Medicare Advantage, is an alternative option to Original Medicare. Part C includes all the benefits covered under Parts A and B, and in many cases also includes Part D prescription drug coverage. In this way, Part C is like a bundled plan option.
These Medicare Advantage plans often times include benefits not covered by Original Medicare. Such benefits might include vision, dental, hearing, and wellness programs.
Private insurance companies provide Medicare Advantage plans, so they have their own enrollment process separate from the Original Medicare enrollment through Social Security.
Part C includes:
Benefits covered under Part A
Benefits covered under Part B
In many cases, Part C also includes:
Benefits covered under Part D
Medicare Part D (Prescription Drug Coverage)
Medicare Part D helps to cover the cost of your prescription drugs. Part D plans vary in coverage. Each plan comes with a list of the prescription drugs it covers. Medicare enrollees can choose a plan that covers their specific prescription drugs and medications.
Similar to Part C, it is private insurance companies that provide these plans with their own enrollment processes separate from Original Medicare.
Part D Covers:
Medicare Supplement Plans (Medigap)
Original Medicare won’t cover all of your healthcare costs. So, many enrollees add to their coverage with a supplement plan, also known as Medigap. This supplemental coverage can help pay for your out-of-pocket costs. Medigap plans vary in coverage to meet differing care and financial needs.
Private insurance companies offer supplement plans, so they have their own enrollment process separate from Original Medicare.
Medigap Plans Cover:
Costs and benefits not covered by Original Medicare
When Should I Enroll in Medicare?
You should enroll in Medicare 3 months before you turn 65.
Your initial enrollment period begins in the three months prior to your 65th birthday. It includes your birthday month then extends for the three months after it. At this time, you can enroll in Original Medicare Parts A and B. At the very least, you should enroll in Part A, as you are not required to pay any monthly premiums.
When Should I Enroll in Part B?
Many Medicare recipients choose to enroll in Part B at the same time they enroll in Part A during their Initial Enrollment Period at age 65. However, some individuals choose to postpone their Part B enrollment. Often times these are individuals who are retiring at a later date and do not want to start paying the Part B monthly premium.
While you have the option of postponing Part B enrollment, be aware that delaying enrollment will result in a higher monthly premium when you later enroll. For each 12-month period in which you are eligible for Part B but delay enrollment, your monthly premium cost will increase by 10 percent. If you qualify for a Special Enrollment Period, this premium increase will not apply to you.
When Should I Enroll in Part C or Part D?
Once you’re eligible to enroll in Original Medicare, you’re also eligible to enroll in Medicare Part C or Medicare Part D. While it is not necessary that you enroll when first eligible, keep in mind that delaying enrollment for Part D will result in an increased premium if you choose to enroll later on. For each month that you delay enrollment once you are eligible, your monthly premium will increase by 1 percent.
When Should I Enroll in a Medicare Supplement?
Once you have enrolled in Original Medicare, you have the option of purchasing supplemental coverage. However, the best time to purchase a supplement plan is during your Medicare Supplement Open Enrollment Period. This is the six-month period that starts on the month of your 65th birthday. During this period, you have a guaranteed right to purchase any supplement plan available in your state, regardless of your current health status.
If you don’t enroll during this period, you can still purchase coverage later. However, the guaranteed right to purchase no longer applies. You may also experience higher premiums or a denial of coverage due to your health status.
When Are the Enrollment Periods for Medicare?
Initial Enrollment Period:
Your Initial Enrollment Period for Medicare is a 7-month period that surrounds the month of your 65th birthday. It includes the three months prior to your birthday month, your birthday month, and the three months after your birthday month. Initial Enrollment is your first opportunity to enroll in Medicare.
For Example: Say your birthday is in January, your initial enrollment period would begin in October. This period would include the month of January and extend three months afterwards until the end of March.
If you enroll prior to your birthday month, your coverage will begin on the 1st of your birthday month. If you enroll in your birthday month or in the three months following it, coverage will begin the 1st of the following month.
Open Enrollment Period:
The Medicare Open Enrollment Period runs from October 15 – December 7. During this period, any Medicare recipient can enroll in or change their Medicare plan. Your coverage begins January 1st of the following year.
General Enrollment Period:
The Medicare General Enrollment Period runs from January 1 – March 31. If you did not enroll during your initial enrollment period or during a special enrollment period, this is a chance to enroll. Your coverage begins July 1st of the same year that you enroll.
Medicare Supplement Open Enrollment Period:
The Medicare Supplement Open Enrollment Period is the 6-month period that begins the month of your 65th birthday and extends for 5 months after. This is the best time to purchase supplement insurance as you have a guaranteed right to purchase. Your coverage begins the 1st of the following month.
Special Enrollment Periods
If you did not enroll during your Initial Enrollment period and you meet certain requirements, you may qualify for a Special Enrollment Period.
If you (or a spouse) are covered under an employer group health plan:
You will receive a Special Enrollment Period to sign up for Part A, Part B, or both. You will also have an 8-month Special Enrollment Period starting the month after your employment ends.
If you are leaving your Medicare Part C plan (Medicare Advantage Plan):
You can leave your plan and switch to Original Medicare during the period of January 1 – February 14. If you wish to add Medicare Part D, you must do so within this period. Your coverage begins the 1st of the following month.
Medicare Enrollment Late Penalty
If you don’t qualify for premium-free Part A coverage and you didn’t purchase it when first eligible (Initial Enrollment Period), then you may face a late penalty when you enroll. Your Part A monthly premium will go up by 10%. This penalty will apply for double the amount of years that you were eligible to enroll but did not.
Example: If you enrolled in Part A 2 years late, then you pay a higher premium for 4 years. If 3 years late, you pay a higher premium for 6 years. And so on.
If you didn’t sign up for Part B when first eligible (Initial Enrollment Period), you will likely face a late enrollment penalty when you enroll. This late penalty will apply to your premium for as long as you have Part B coverage. For each full 12-month period that you were eligible to enroll but did not, your premium amount will increase by 10%.
Example: If you enrolled in Part B two and a half years late (or 30 months), then your late penalty is a 20% increase in the standard premium price. It is 20% because there were 2 full 12-month periods during this time. If you had waited 36 months, the late penalty would have been 30% because 3 full 12-month periods occurred.
If your Initial Enrollment Period has ended and you have gone without Part D coverage, Part C coverage, or creditable prescription drug coverage for a continuous period of 63 days then you may be assessed a late penalty to your Part D monthly premium.
The amount of the penalty is determined by how long you went without prescription drug coverage. The late penalty is 1% of the national base beneficiary premium ($32.74) times the number of full months you went without creditable drug coverage.
Example: If you were to go for 16 months without creditable drug coverage once your Initial Enrollment Period has ended then your late penalty is 16% of $32.74 This is 16% for the 16 months without coverage and $32.74 is the national base beneficiary premium amount for 2019. This makes your Part D late enrollment penalty $5.24. This amount will be added to your Part D monthly premium.
Note: Monthly penalties are always rounded to the nearest $.10.
