If you are looking to help your parents enroll in Medicare, you are in the right place. Helping a mom or dad sign up for Medicare is one of the most meaningful ways to care for them. The process has deadlines, coverage choices, and legal permissions that are worth understanding so you can avoid penalties and pick the right plan. This guide is written for adult children who want to help, step by step, without the jargon.
First: understand when your parent should enroll
Medicare does not work on a single date for everyone. The right time depends on your parent’s situation. Here are the three key enrollment periods.
Initial Enrollment Period (IEP), around age 65
The Initial Enrollment Period lasts 7 months: it starts 3 months before the month your parent turns 65, includes the birthday month, and ends 3 months after. This is the main window to sign up for Part A and Part B. If your parent is already getting Social Security, enrollment is usually automatic. If they are not yet receiving Social Security, they have to sign up actively through the Social Security Administration (SSA). You can review the official rules at Medicare.gov.
General Enrollment Period (GEP), January 1 to March 31
If your parent missed their window and does not qualify for a special period, they can sign up during the General Enrollment Period, from January 1 to March 31 each year. Coverage starts the first day of the month after they enroll.
Special Enrollment Period (SEP), if they worked past 65
Many people keep working past 65 and have health coverage through their job (or a spouse’s job). In that case, they can usually delay Part B without a penalty. When that job or coverage ends, an 8-month Special Enrollment Period opens to sign up penalty-free. This is one of the situations where help matters most, because it is easy to let the deadline slip. The SSA explains the SEP at SSA.gov.
The parts of Medicare, made simple
Before choosing a plan, it helps to know what each part covers:
- Part A (hospital): inpatient hospital stays, some skilled nursing care, and hospice care. Most people pay no premium for Part A.
- Part B (medical): doctor visits, preventive care, tests, and outpatient services. It has a monthly premium.
- Part D (drugs): covers prescription drugs. It is added separately or built into a Medicare Advantage plan.
Original Medicare vs. Medicare Advantage
This is where most questions come up when helping a parent:
- Original Medicare (Part A + Part B): lets them see almost any doctor or hospital in the country that accepts Medicare. Many people add a drug plan (Part D) and sometimes a supplement policy (Medigap).
- Medicare Advantage (Part C): these are private plans approved by Medicare that bundle Part A, B, and usually D, sometimes with extra benefits. They typically use provider networks, so it is worth confirming your parent’s doctors are in the network.
If your parent already has Medicare Advantage, it is worth reviewing the benefit changes each year. We cover this in our guide on Medicare Advantage benefit cuts in 2026.
Watch out for late enrollment penalties
One of the most important reasons to help on time is to avoid penalties that can last for life.
- Part B: the penalty is 10% for each full 12-month period your parent could have signed up but did not. That penalty is added to the monthly premium and is usually paid for as long as they have the coverage.
- Part A (when they have to buy it): the premium can go up 10%, and that penalty is paid for twice the number of years they went without signing up.
- Part D: there is also a late enrollment penalty if they went a long time without drug coverage.
The official details are at Medicare.gov. That is why it pays to mark the dates on a calendar and act within each period.
How to get permission to speak for your parent
Even though you are their child, Medicare and Social Security cannot share information or take instructions from you without authorization. To handle things for them, there are formal options:
- Medicare authorization (1-800-MEDICARE): your parent can authorize Medicare to talk to you by completing the form that lets Medicare release their personal information.
- Appoint a representative: for Medicare claims, appeals, or grievances there is an “Appointment of Representative” form (CMS-1696). By signing it, your parent gives you authority to handle that matter.
- SSA representative (SSA-1696): if the matter is with the SSA, Form SSA-1696 appoints a representative. See SSA.gov.
For simple tasks, such as helping fill out a form, interpreting, or driving them to an office, a formal appointment is usually not needed. But to speak for them on the phone or receive their information, authorization is required.
Common mistakes worth avoiding
- Assuming enrollment is always automatic. It only is if they are already getting Social Security.
- Letting the special period slip after they stop working, and getting a penalty.
- Choosing a Medicare Advantage plan without confirming their trusted doctors are in the network.
- Not checking the drug coverage (Part D) against the prescriptions they actually take.
- Trying to handle things for them without the signed authorization, so Medicare cannot help you.
Help with costs: Extra Help and Savings Programs
If your parent’s income is limited, there may be help to lower costs:
- Extra Help: a federal program that helps pay premiums, deductibles, and copays for drug coverage (Part D). You apply through Social Security. More information at SSA.gov.
- Medicare Savings Programs (MSPs): help pay premiums and, in some cases, Part A and B deductibles and copays. These programs are run by each state, so the rules and income limits vary by state. It is best to check eligibility at Medicare.gov and with your state.

Frequently asked questions
Can I enroll my parent in Medicare online?
The Medicare application is done through Social Security, online, by phone, or at a local office. To handle it for them and receive information, you first need their signed authorization; without it, Social Security and Medicare cannot share details with you.
My mom is still working at 65. Does she have to enroll now?
If she has active health coverage through her job (or a spouse’s job), she can often delay Part B without a penalty. When that job or coverage ends, an 8-month special period opens to enroll penalty-free. It is best to confirm her case with Medicare or an advisor.
What if we missed the enrollment deadline?
If no special period applies, they can sign up during the General Enrollment Period, January 1 to March 31. They may owe a late enrollment penalty that is added to the monthly premium, usually for life.
Original Medicare or Medicare Advantage for my dad?
It depends on his doctors, his medications, and his budget. Original Medicare offers the freedom to choose almost any doctor that accepts Medicare; Medicare Advantage often includes drugs and extra benefits, but with provider networks. It is worth comparing both before deciding.
Is there help if my parents have low income?
Yes. Extra Help assists with drug coverage costs and is requested through Social Security. Medicare Savings Programs help with premiums and other costs, but they are run by each state, so eligibility varies. Check at Medicare.gov and with your state.
What form does my parent sign so I can help?
For Medicare to talk to you, your parent completes the Medicare authorization form. For claims or appeals, there is form CMS-1696. For Social Security matters, form SSA-1696 appoints a representative.
