Ask Social Security Questions and Get Answers ASAP
If you have insurance through your employer then you are fine there.
Most workers probably should enroll in Medicare Part A, which is free for most people and covers institutional care in hospitals and skilled nursing facilities, as well as certain care given by home health agencies and care provided in hospices. But ask your employer (or your spouse’s employer, if that’s where you get your coverage) whether your current coverage will change in any way if you enroll in Medicare, even just Part A.
Only your employer can tell you that because they know the plan you have.
Whether you should enroll in Part B while you are still working depends on whether your employer has more than 20 employees.
Most of what you need to know can be found through your employer.
