If someone takes Social Security early, will they be automatically enrolled in Part A and Part B of Medicare later on?
If you are enrolled in Social Security, when you turn 65 the federal government enrolls you in Part A and Part B of Medicare. They will also send your Medicare card. You do not have to proactively enroll in Medicare A and B if you’ve already enrolled in Social Security.
The only person who has to enroll in A and B of Medicare is someone who is putting off Social Security enrollment until a later date. In that case, enrollment in Medicare should occur about 90 days prior to their 65th birthday.
