Why Enroll in Medicare at Age 65?

Once you reach the age of 65, you most likely qualify for Medicare. This means that you get access to federal health insurance. Medicare has four different service types:
  • Part A: This covers hospital stays, care in a nursing facility, hospice, and some home health care.
  • Part B: This is for medical insurance and covers some services from doctors, outpatient care, preventative care, and medical supplies.
  • Part D: This is for prescription drugs, including some shots and vaccines.
Medicare Advantage is an option for those looking to get additional coverage; private insurance companies approved by Medicare can offer prescription drug coverage, dental care, and more. Most people qualify for parts A and B, and only have to pay monthly premiums for part B. For many, Medicare is an important benefit and a way to get medical coverage; the toughest part is simply figuring out how to enroll in Medicare after 65.

Who Should Enroll in Medicare at Age 65?

Many people don’t need to enroll in Medicare because it happens automatically. If you’re already receiving Social Security retirement benefits or Railroad Retirement Board benefits, then you’ll be automatically enrolled in Medicare.

Do you have to sign up for Medicare at age 65 if you are still working? You don’t. If you have health insurance already through your employer (and your employer has more than 20 employees), you may not want to sign up right away for part B of Medicare as you’ll have to pay monthly premiums.

However, make sure you check with your employer to see if your coverage changes once you become eligible for Medicare. Keep in mind you may have to pay a higher premium for part B when you do enroll, if you don’t sign up right away.

If you don’t have retirement benefits already and you don’t have an insurance plan through your work, then you should enroll in Medicare as soon as possible once your 65th birthday approaches.
