Demystifying Medicare — What You Need to Know Before 65 (and After)
Planning Alternatives October 1, 2025

Approaching Medicare eligibility (usually at age 65) can feel overwhelming. There are multiple parts, deadlines, costs, and choices — and making a misstep can mean penalties or less coverage. Joanne Giardini-Russell, founder of Giardini Medicare, breaks down the system clearly so you can make informed choices. Here’s what you should know.
What is Medicare? The Basics
- Part A covers hospital stays, inpatient care.
- Part B handles outpatient services, doctor visits, preventive services.
- Part D is prescription drug coverage (not automatic; must enroll or pick a plan).
- Part C (Medicare Advantage) bundles A, B, and often additional benefits (vision, dental, etc.); may have networks, extra restrictions.
- Medigap (Supplement Plans) help cover costs not covered by Original Medicare (coinsurance, copays, etc.).
Key Decision Points & Timing
- When to enroll: The Initial Enrollment Period (IEP) around your 65th birthday is critical. Delaying may result in penalties unless you qualify for a Special Enrollment Period (if still working with employer coverage, etc.)
- Working past 65: If you have employment-based coverage, you might be able to delay some parts, but it depends on your employer size and whether that coverage is “creditable.”
- Annual review: Even after you enroll, things change (premium increases, plan changes, drug coverage changes), so reviewing your plan every year during the Annual Election Period is vital.
Comparing Your Options: Advantage vs Original + Supplement
Insurance Type & Feature | Medicare Advantage (Part C) | Original Medicare + Medigap + Part D |
---|---|---|
Network restrictions | Often yes | Usually more flexibility |
Additional benefits (vision/dental) | Often included | Buy separately or out of pocket |
Out-of-pocket max limits | Usually present | Can be higher, more unpredictable |
Premium costs vs extras | Sometimes lower premium but trade-offs | More predictable costs but may cost more overall |

Cost Considerations
- Premiums: For Parts B & D, plus Medigap or Advantage plan fees.
- Income-related surcharges (IRMAA): If your income is above certain thresholds, you pay more.
- Out-of-pocket costs: Deductibles, copays, coinsurance, etc. These vary widely depending on plan and your health care usage.
- Prescription drugs: Good drug plans can save money; mis-matching a drug plan can lead to high costs.
Avoiding Common Pitfalls
- Assume advertising is complete: always read the fine print. “Zero premium” Advantage plans often have trade-offs.
- Missing deadlines: Late enrollment penalties can apply for Part B or Part D.
- Not reading plan changes: Plans change yearly — drug formularies (which drugs are covered), co-pays, network, etc. A plan that was good one year may not be next.
- Not considering long-term needs and travel/out-of-network care: Your preferences matter.Action Steps:
What Should You Do Now?
- Start planning about 6 months before you turn 65 — understand what your current coverage provides, What options will be available.
- Gather your health & financial info — what medications you take, how often you use medical services, your income, etc.
- Consult reliable sources — e.g. independent brokers, state health insurance programs, or nonprofits; avoid high-pressure sales.
- Use “what if” scenarios — model what your costs would be under different plans given your expected usage.
- Review yearly during open enrollment — your needs or plan offerings may change.
Conclusion
Medicare doesn’t have to be a mystery. By understanding the pieces, asking the right questions, and planning ahead, you can make choices that protect your health and your wallet. As Joanne Giardini-Russell emphasizes, the objective is to find the coverage that fits you, not what works for someone else.
