I’m working past 65. What do I do about Medicare?

A lot of people work past age 65. Many have health insurance through their employers. Depending on your situation as you turn 65, you may or may not have to enroll in Medicare. However, you may want to consider enrolling in Medicare Part A even if you are still working.

Check with your employer’s human resources department to see if signing up for Original Medicare (Part A and/or Part B would be a good idea for you. They should also be able to tell you if your employer requires you to enroll in Original Medicare.
