Turning 65 and becoming eligible for Medicare is a major life milestone. But between understanding different coverage options, navigating enrollment deadlines, and researching plans in Minnesota, it's easy to feel overwhelmed. This checklist breaks down the process into manageable phases so you can prepare with confidence.
Use this as your roadmap to make sure you don't miss any critical deadlines or overlook important decisions.
6 Months Before Your 65th Birthday
Start your research early. You don't need to enroll yet, but understanding your options will make the decision easier when enrollment opens.
What to Do Now
- Gather documents: Social Security card, birth certificate, and any employer coverage information
- Review your current health insurance coverage (if you have it through work or individually)
- Make a list of your doctors, specialists, and preferred hospitals
- List all prescription medications you take regularly
- Estimate your annual healthcare usage (frequent doctor visits? chronic conditions?)
- Understand your budget for healthcare premiums and out-of-pocket costs
- Review the three main paths: Original Medicare + Medigap vs. Medicare Advantage vs. staying on employer coverage
- Bookmark Medicare.gov and Minnesota-specific resources
3 Months Before Your 65th Birthday
Your Initial Enrollment Period (IEP) is about to open. This is when you can enroll in Medicare without restrictions. Make your major decisions now.
What to Do Now
- Decide: Original Medicare + Medigap vs. Medicare Advantage
- Compare Medicare Advantage plans available in your area and verify your doctors are in-network
- If choosing Original Medicare, select a Medigap plan (Plan G is popular)
- Make your Part D (prescription drug) selection based on your medications
- Enroll in Part A and Part B (your IEP is now open; enrollment takes effect next month)
- If choosing Medicare Advantage, enroll in your selected plan
- Document when you enroll to track your coverage start date
- If you're keeping employer coverage, understand how it coordinates with Medicare
At Your Birthday Month & Shortly After
Your Initial Enrollment Period runs through the 3rd month after your birthday month. Use this window to finalize any remaining decisions.
What to Do Now
- Confirm your Part A and Part B coverage is active (check your Medicare.gov account)
- If you chose Original Medicare and Medigap, finalize your Medigap enrollment (6-month window is open)
- Verify your Part D plan is active and your medications are covered
- If you enrolled in Medicare Advantage, verify your plan start date and in-network status of your doctors
- Set up your Medicare.gov account if you haven't already
- Review your Medicare Summary Notice (you'll receive this by mail)
- Notify your current insurer if you're dropping coverage
- Get new Medicare ID card when it arrives (keep it in a safe place)
Your IEP window closes
After the 7-month Initial Enrollment Period ends, you'll need to wait until the Annual Enrollment Period (October 15 - December 7) to make changes. If you miss your IEP without good reason, late enrollment penalties may apply permanently.
Making the Big Decision: Original Medicare + Medigap vs. Medicare Advantage
Which Path is Right for You?
Original Medicare + Medigap
- See any Medicare-accepting doctor
- No provider network restrictions
- Predictable monthly costs
- Good if you travel frequently
- Flexibility to change doctors easily
- Higher total monthly premiums
Medicare Advantage
- Often lower or no monthly premium
- Bundled coverage (A, B, usually D)
- May include dental, vision, hearing
- In-network provider requirement
- Annual out-of-pocket maximum
- Variable costs based on usage
Consider your health, your doctors, your budget, and your lifestyle. If you want more information, see our detailed guide to Medicare Advantage vs. Medigap.
What If You're Still Working at 65?
Employer coverage coordination
If you're still working and have employer health insurance, you may be able to delay Medicare enrollment without penalties—but only under certain conditions. If your employer has 20 or more employees, you can typically stay on employer coverage and delay Medicare. However, you should still enroll in Part A at 65 to protect yourself. Consult with your employer's benefits department and understand your specific situation before delaying enrollment.
