In this class, we discussed how Medicare interacts with employer coverage, focusing on when and how they work together. As people approach Medicare eligibility, it’s important to understand the key differences depending on the size of the employer and how it affects their health coverage choices.

Key Takeaways and Next Steps

Medicare and Large Employers (20+ Employees)

If you are covered by an employer with 20 or more employees, you may defer enrolling in Medicare Part A and Part B.
In this case, your employer plan remains your primary insurance, and Medicare is secondary if you opt into Part A.

Medicare and Small Employers (Under 20 Employees)

For employers with fewer than 20 employees, Medicare becomes your primary insurance when you turn 65.
You will need to enroll in both Medicare Part A and Part B to ensure full coverage. Your employer plan will become secondary, meaning it will only cover costs after Medicare.

Deferring Medicare Part A and Part B

If you are still working and your employer's plan is your primary coverage (20+ employees), you can delay Medicare enrollment, but should carefully consider enrolling in Part A as it is usually premium-free.
Delaying Part B is common to avoid the monthly premium, but always review your situation with HR or a benefits specialist.

Small Employer Plans and Group Plan Options

If Medicare is your primary coverage in a small group setting, it’s crucial to understand how it coordinates with your employer plan, or consider switching to a Medicare Advantage or Medigap policy.
