Helping a parent enroll in Medicare can feel confusing at first, but the process is usually straightforward once you understand the available options and enrollment periods.
If your parent is not automatically enrolled in Medicare Part A, you can assist them in signing up during their Initial Enrollment Period (IEP). Enrollment can be completed online, by phone, or in person through the Social Security Administration.
Below is a step-by-step guide to help you navigate the process.
Automatic Medicare Enrollment at Age 65
When your parent turns 65 years old, they are usually automatically enrolled in Medicare Part A if they already receive benefits from the Social Security Administration or the Railroad Retirement Board.
If this applies, their Medicare card and welcome packet will typically arrive around their 65th birthday.
However, if they are not receiving Social Security or Railroad Retirement benefits, they will need to enroll manually.
How to Enroll Your Parents in Medicare Online
The fastest and easiest way to enroll is through the Social Security Administration website.
Medicare consists of several parts, and your parent can choose coverage that best fits their healthcare needs.
Original Medicare
Medicare includes:
- Part A: Covers inpatient hospital care
- Part B: Covers outpatient medical services
Many people with Original Medicare also enroll in Part D, which provides prescription drug coverage for medications taken at home.
During the online application process, you may need:
- Your parent’s Social Security number
- Their Social Security card
- Personal identification details
Having this information ready will make the process quicker and easier.
Medicare Advantage (Part C)
Some people choose Medicare Advantage instead of Original Medicare.
Medicare Advantage plans combine Part A and Part B coverage and are offered by private insurance companies approved by Medicare. Many plans also include:
- Prescription drug coverage
- Dental benefits
- Vision care
- Hearing services
- Fitness programs
Because these plans vary by location, you can use Medicare’s Plan Finder tool to search for options available in your parent’s ZIP code.
Enrolling by Phone or In Person
If online enrollment feels complicated, your parent can enroll by phone or in person.
Phone Enrollment
Call the Social Security Administration at:
800-772-1213
Explain that you would like to enroll your parent in:
- Medicare Part A
- Medicare Part B
- Or both
In-Person Enrollment
You can also visit a local Social Security office with your parent. Use the SSA website to locate the nearest office.
When Can Your Parents Enroll in Medicare?
Medicare has several important enrollment periods.
Initial Enrollment Period (IEP)
The Initial Enrollment Period lasts 7 months and begins around your parent’s 65th birthday.
It includes:
- 3 months before their birthday month
- Their birthday month
- 3 months after their birthday
Enrolling during this period helps avoid late enrollment penalties.
Medicare Advantage Open Enrollment Period
If your parent already has a Medicare Advantage plan, they can make changes during the Medicare Advantage Open Enrollment Period.
Dates: January 1 – March 31 each year.
During this time they can:
- Switch to another Medicare Advantage plan
- Return to Original Medicare
Medicare Annual Open Enrollment Period
The Annual Open Enrollment Period (AEP) runs from:
October 15 – December 7 each year
During this time your parent can:
- Switch from Original Medicare to Medicare Advantage
- Change Medicare Advantage plans
- Add or remove prescription drug coverage (Part D)
