4. After you retire you forget about Medicare Part B Enrollment Deadline
If your place of work offers you coverage (and your employer has more than 20 employees), then you don’t need to worry about signing up for Medicare when you reach the age of 65. However, you can opt to keep your coverage through the employer, and that way you won’t have to pay for the Part B premiums.
But, bear in mind that after you leave your job you have to sign up in the next 8 months, unless you want to wait till July 1st to get coverage. And you don’t want to spend several months without coverage, do you?
5. You don’t sign up for Medicare Part B if you own Retiree or COBRA coverage
When you are 65 years old if you have coverage through a current employer (with more than 20 employees), that is considered to be your primary insurance, besides Medicare. Be aware that other coverages like retiree coverage, severance benefits, or COBRA can’t be your primary coverage after the age of 65.
So, if you don’t sign up for Medicare you can have gaps in your coverage and that also means you are getting a penalty for every year you should have been enrolled in Part B, which is worth 10% of your current Part B premium.
