Disclaimer64Plus is an independent educational software platform. We do not sell Medicare plans, generate or sell leads, recommend one insurance company over another, or receive compensation based on plan enrollment. Our platform provides educational information and decision-support tools to help users better understand Medicare. Users may independently contact Medicare, licensed insurance agents, or insurance companies if they choose to enroll in coverage.
Medicare for active employees
If you're an employee approaching 65 or planning your retirement, understanding how Medicare interacts with your employer benefits is crucial. The rules depend on your employer's size, your employment situation, and when you plan to retire.
Distribution of employee Medicare status
Turning 65 while working
Your options depend on your employer's size. The rules differ for large employers (20+ employees) versus small employers (fewer than 20 employees).
Large employer
- Employer coverage is primary
- You can delay Part B without a penalty
- You should still enroll in Part A (free)
- 8-month SEP when you stop working
Small employer
- Medicare becomes primary at 65
- You must enroll in Parts A and B on time
- Employer plan becomes secondary
- Late-enrollment penalties apply
Enrolling in Part A at 65 is generally recommended even if you're still working. It's free and provides hospital coverage. However, if you have an HSA, enrolling in Part A may affect your ability to contribute.
Transitioning from employer coverage to Medicare
When you retire or lose employer coverage, you'll need to transition to Medicare. Plan ahead to ensure there are no gaps in coverage.
Start planning
Compare Medicare options, understand costs, and decide between supplements or Advantage plans.
Enroll in Medicare
Enroll in Parts A and B if you haven't already. Choose a Part D or Medicare Advantage plan.
Coverage ends
Employer coverage typically ends on your last day or at the end of the month.
Medicare begins
Your new Medicare coverage is active. Save employer documentation for your records.
Choose Medigap
If you choose Original Medicare, this is your guaranteed-issue period for Medigap.
Cost comparison: employer vs Medicare

Clear guidance on how 64Plus works alongside your employer benefits, so you can plan retirement healthcare with confidence.
64Plus helps you understand Medicare, your employer health benefits, and the transition to retirement healthcare. You can ask questions anytime and receive clear, easy-to-understand guidance to help you make informed decisions about your coverage.
It depends on factors such as your age, your employer's coverage, and the size of your employer. 64Plus can help you understand your options, important enrollment deadlines, and whether delaying Medicare enrollment could result in penalties.
Yes. 64Plus can help you understand the differences between your employer-sponsored health plan and Medicare, including costs, coverage, provider access, prescription drug benefits, and other important considerations as you prepare for retirement.
No. Your conversations with 64Plus are private. Your employer does not have access to your personal questions or conversations unless you choose to share that information.
The best time to start learning about Medicare is several months before you become eligible. 64Plus can help you understand important enrollment dates, explain what actions you should take, and guide you through each step of the transition so you don't miss critical deadlines or incur avoidable penalties.
Don't miss a deadline
Know your Medicare enrollment windows.
Timing matters with Medicare. Missing a window can mean lifelong penalties, so here are the key periods to keep on your radar.
Around your 65th birthday
Initial Enrollment
Your 7-month window: the three months before your birthday month, the month itself, and the three months after.
Oct 15 to Dec 7
Annual Enrollment
Switch, join, or drop Medicare Advantage and Part D plans for the year ahead.
Jan 1 to Mar 31
Advantage Open Enrollment
Already on Medicare Advantage? Change plans once, or switch back to Original Medicare.
After a life event
Special Enrollment
Moving, losing coverage, or other qualifying changes can open a window outside the usual dates.
Medicare Assistant keeps track of these windows with you, so you never miss a deadline or face a late penalty.
