What Do You Do About Medicare if You’re Working Past 65?
A lot of people reach the age of Medicare eligibility and continue to work. 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. You may want to consider enrolling in Medicare Part A even if you are still working.
For most people, Part A does not charge a Premium. And if you are required to pay a premium for Part A but don’t sign up during IEP, your monthly premium may increase by 10%. As for Part B, which does come with a monthly premium, your options to sign up will be determined by the size of your employer.
Check with your benefits administrator to see if signing up for Original Medicare Part A and/or 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.
If you don't enroll in a Medicare plan, your employer's plan may not cover services that Medicare covers.
Talk to your employer for assistance with making the best decision for your coverage needs.
