If you’ve received retirement benefits for at least four months before you turn age 65, you are enrolled automatically in Medicare A and B. You can opt out of Part B if you are still covered under an employer-sponsored group health plan. If you wait to enroll in Part B and don’t have group coverage, you may have to pay a penalty.
If you have not received retirement benefits, you will need to self-enroll. Sign up for Medicare through Social Security or call (800) 772-1213. If you were a railroad worker, visit the RRB website or call (877) 772-5772.
If you are within three months of becoming age 65 and you are not yet ready to be receiving Social Security, you can apply online for Medicare only through Social Security and use their tools to find out information like eligibility premium, along with details about Medicare part hospital, Medicare part medical, Medicare supplement,. And what you can do so you do not pay late enrollment fees.
Medicare enrollment opportunities
- Initial Enrollment Period (IEP): This is the best time to enroll in Medicare if you aren’t automatically enrolled. This seven-month period starts three months before the month you turn 65, includes your birthday month, and extends three months after your birthday month. If you enroll during the first three months of your IEP, your Medicare coverage will start on the first of the month you are age 65. If you enroll in months four through seven of your IEP, your Part A coverage will be retroactive to the first day of your birthday month. Your Part B coverage will be delayed two to three months.
- Open Enrollment Period (OEP): If you miss your IEP, you can enroll in Medicare during this time which occurs annually between January 1 and March 31. Coverage starts on July 1.
- Special Enrollment Period (SEP): You may qualify for a SEP if your circumstances change following initial enrollment. For example, you change where you live, or you lose your group coverage. Depending on your circumstance, you will have a period of time to enroll in Medicare without penalties. Coverage typically starts the first of the month following enrollment.
What’s important to know is that you could face a late enrollment penalty if you neglect to enroll in coverage during these periods.
How Do You Enroll in Medicare Supplement, Medicare Advantage (Part C), and Medicare Prescription Plans?
Medigap, Medicare Part C, and Medicare Prescription Drug plans are administered by private insurance companies approved and regulated by Medicare. The company you choose or a licensed agent can help with your enrollment. During your time working, you pay medicare taxes through your employer. Medicare taxes allow this health insurance coverage to be available.
As for finding plans, you can view options on Medicare.gov, where there is also a premium calculator and you can learn more about part coverage. An explanation of each:
- Medigap: You must have Original Medicare to purchase a Medigap plan. You can enroll during your IEP. If you only have Part A but have not enrolled in Part B yet, you can enroll in a Medigap plan with guaranteed issue rights within six months after you are 65 and have Part B. You cannot have both a Medicare Advantage Plan and a Medigap plan. Suppose you drop your Medicare Advantage Plan and return to Original Medicare within the first year of having a Medicare Advantage Plan. In that case, you may be able to purchase a Medigap plan. If you wait, you may not be able to purchase a Medigap plan or may have to pay more based on your health condition.
- Medicare Advantage: You must have Part A and Part B to enroll in a Medicare Advantage Plan. You can join a plan during your IEP or the annual OEP from October 15 through December 7. If you already have a Medicare Advantage Plan, you can make a change during the OEP from January 1 through March 31. See 2022 Medicare Advantage Plans here.
- Prescription Drug Plan (Part D): You must have Part A and Part B to enroll in a Medicare drug plan, either through your Medicare Advantage Plan or a stand-alone drug plan. You can enroll during your IEP or during the annual OEP from October 15 through December 7. Suppose you are in a Medicare Advantage Plan with drug coverage. In that case, you can switch to another Medicare part or switch back to Original Medicare plus a stand-alone drug plan one time during the OEP from January 1 to March 31. See 2022 drug plans here.
