01 · Introduction
A Note Before You Begin
This guide is designed to walk you through what Medicare actually costs, what it covers (and doesn't), and the decisions that determine your financial exposure for the rest of retirement.
To Our Clients
Dear Friend,
Most people approaching 65 assume Medicare is the finish line — the moment the government finally steps in and takes care of healthcare. The reality is more complicated, and in some ways more expensive, than they expect.
Medicare has premiums, deductibles, income-based surcharges, and enrollment windows that carry permanent consequences if you miss them. The decisions you make two to three years before you turn 65 directly affect what you pay the moment you enroll.
This guide isn't meant to frighten you — it's meant to make sure you walk into these decisions fully informed. The clients who avoid Medicare's biggest surprises are almost always the ones who planned ahead. The good news is that with the right strategy, most of these traps are completely avoidable.
Read through this carefully. Use the tools. Then let's talk.

02 · Medicare 101
What You Actually Get
Medicare is divided into parts — each covering different services, with different costs and different rules. Most people only know Part A. Here's what all four actually do.
Medicare is not a single plan that covers everything. It's a patchwork of parts with real gaps — and the decisions you make about filling those gaps determine how much you pay when you actually get sick.
A
Hospital Insurance
Inpatient Care, Skilled Nursing, Hospice
Covers hospital stays, skilled nursing facility care after a qualifying hospital stay, and hospice. Most people don't pay a Part A premium because they paid into Medicare through payroll taxes for 10+ years.
⚠ Gap: $1,676 deductible per benefit period — not per year. Long hospital stays can trigger multiple deductibles.
B
Medical Insurance
Doctors, Outpatient Services, Labs
Covers doctor visits, outpatient procedures, preventive care, lab tests, and most of what you'll actually use in retirement. Standard premium is $185/month in 2025 — but this rises with income via IRMAA.
⚠ Gap: 20% coinsurance with no out-of-pocket maximum. A $500,000 surgery leaves you exposed to $100,000+.
C
Medicare Advantage
Bundled Coverage Through Private Insurers
Private insurance plans approved by Medicare that combine Parts A and B (and often D). May include dental, vision, and hearing. Often lower monthly premiums — but comes with networks and prior authorization.
⚠ Gap: Limited networks, prior authorizations, and out-of-pocket maximums up to $8,850/year can be costly if you're seriously ill.
D
Prescription Drug Coverage
Outpatient Prescription Medications
Covers prescription drugs through private plan providers. Plans vary widely in premium, formulary, and cost-sharing. Also subject to IRMAA income surcharges above certain income thresholds.
⚠ Gap: Formularies change annually — a drug that was covered this year may cost far more next year without notice.
The Medigap Bridge. None of these parts fully cover you. A Medicare Supplement (Medigap) policy fills Original Medicare's gaps — covering the 20% coinsurance and deductibles with predictable premiums. Your decision between Medigap and Medicare Advantage is one of the most important choices you'll make at 65.

Three Traps That Catch Most People
You don't know you've hit these until it's too late to undo the damage. Each of these mistakes is permanent or extremely costly to reverse.
$5,940
IRMAA — Income Surcharge
Your 401(k) May Be Secretly Raising Your Premiums
If your retirement income exceeds certain thresholds, Medicare charges you extra for Parts B and D on top of regular premiums. Most pre-retirees have no idea that 401(k) and IRA withdrawals can push them into a surcharge bracket.
⚠ Income-Based Penalty
+10%
Per Year You Were Late
The Late Enrollment Penalty Never Goes Away
Miss your Part B enrollment window without qualifying employer coverage and you pay a 10% penalty for every 12-month period you were late — permanently added to your monthly premium for the rest of your life. No appeals. No exceptions.
⚠ Lifetime Penalty
2 Yrs
The IRMAA Lookback Trap
What You Did at 63 Affects What You Pay at 65
Medicare uses your income from 2 years ago to set surcharges today. A large Roth conversion, IRA withdrawal, or property sale in one year affects what you pay two years later. Planning in the moment is already too late.
⚠ Two-Year Lag
The common thread: All three of these traps are driven by income decisions made before retirement. The window to protect yourself closes quietly — which is why a Medicare-aware income strategy needs to begin years before age 65, not at enrollment.

The lookback matters: These surcharges are based on your income from two years prior. If you're 63 today, your 2025 income determines your 2027 Medicare premiums. Roth conversions, income timing, and tax-free distributions can all reduce your bracket before it locks in.
05 · Enrollment Windows
The Deadlines That Can't Be Undone
Missing the wrong enrollment window isn't just inconvenient — the consequences are permanent. Here's every window you need to know and what happens if you miss it.
⏰
Initial Enrollment Period
7 Months Around Age 65
Starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. This is your primary window. Miss it without qualifying employer coverage and the lifetime penalty begins immediately — no appeals, no exceptions.
⚠ Miss it = Lifetime penalty
📅
General Enrollment Period
January 1 – March 31 Annually
If you missed your Initial Enrollment Period, this is your fallback — but coverage doesn't start until July 1, and you'll already be accumulating the late enrollment penalty. It's a delayed escape, not a clean one. The penalty stays.
⚠ Late penalty applies
✅
Special Enrollment Period
8 Months After Qualifying Coverage Ends
If you have active employer group health coverage past 65 through your own or a spouse's job, you qualify for a Special Enrollment Period when that coverage ends. You have 8 months to enroll in Part B without penalty. Keep your documentation — SSA will ask for it.
✅ No penalty if done right
🔄
Annual Enrollment Period
October 15 – December 7 Each Year
Your annual window to switch Medicare Advantage plans, change Part D drug plans, or move between Medicare Advantage and Original Medicare. Changes take effect January 1. Important: you cannot use this window to add Medigap if you're switching from Medicare Advantage — medical underwriting applies.
⚡ Plan changes only
The COBRA trap: COBRA coverage from a former employer does NOT qualify you for a Special Enrollment Period. If you're relying on COBRA past 65, you must still enroll in Part B during your Initial Enrollment Period or face the lifetime penalty.
06 · Coverage Choice
Medigap vs. Medicare Advantage — The Real Trade-Off
This is the most consequential Medicare decision you'll make — and most people choose based on the wrong information. Here's what you actually need to weigh.
Option A
Medigap (Medicare Supplement)
Predictable costs — fixed monthly premiums with no out-of-pocket surprises
No networks — see any Medicare-accepting provider nationwide
Best for serious illness — covers what Original Medicare doesn't
No prior authorization required for covered services
Higher monthly premiums than Medicare Advantage plans
Typically no dental, vision, or hearing included
Medical underwriting applies if you try to switch later (outside open enrollment)
Best for: Predictability & serious health needs
Option B
Medicare Advantage (Part C)
Lower or zero monthly premiums — attractive upfront cost
Often bundles dental, vision, hearing, and fitness extras
Annual out-of-pocket maximum (up to $8,850 in 2025)
May include Part D drug coverage built in
Network restrictions — limited provider choice, especially outside your region
Prior authorizations for procedures can delay or deny care
Switching back to Medigap may require medical underwriting — coverage can be denied
Best for: Healthy enrollees who want bundled extras
The underwriting trap: When you first enroll at 65, you have a guaranteed right to buy any Medigap plan. After that, if you try to switch from Medicare Advantage back to Medigap, insurers can medically underwrite you — and deny coverage based on pre-existing conditions. This makes your initial choice far harder to reverse than most people realize.
07 · Income Strategy
How to Build a Medicare-Proof Income Plan
The income sources you draw from in retirement determine your IRMAA bracket, your Social Security taxation, and your overall tax burden. Not all income is created equal.
The goal is a layered income strategy — one that draws from the right buckets at the right time to keep your MAGI as low as possible while still meeting your income needs. Done right, you can legally reduce or eliminate IRMAA surcharges entirely.
Tax-Deferred Income — Counts Against You
401(k) and traditional IRA withdrawals, pension income, and required minimum distributions (RMDs) all count toward your MAGI for IRMAA purposes. This is where most retirees get surprised — the retirement savings they spent decades building ends up quietly triggering Medicare surcharges. The more you have saved in pre-tax accounts, the more carefully you need to plan your income sequencing in the years before and after 65.
Taxable & Earned Income — Also Counts
Part-time wages, self-employment income, interest, dividends from taxable brokerage accounts, and capital gains all count toward your MAGI. Social Security benefits also count if your total income is above certain thresholds. If you claim Social Security before your Full Retirement Age and continue working, SSA may also temporarily withhold some benefits if earnings exceed annual limits.
Tax-Free Income — Your Best Defense
Roth IRA distributions and properly structured life insurance policy loans do NOT count toward IRMAA income calculations. Drawing from these sources in retirement can keep you well below the brackets where Medicare surcharges kick in — legally reducing or eliminating the IRMAA burden entirely. This is one of the most powerful arguments for building a tax-free income layer in the years before retirement.
The Roth conversion window: The years between retirement and age 65 (or between 65 and RMD age) are often your best opportunity for Roth conversions — income is lower, brackets are wide, and you still have time to lower your IRMAA exposure before the 2-year lookback locks in your surcharge.
08 · Myths vs. Reality
What Medicare Recipients Believe — and What's Actually True
Click any myth below to see the reality — and what it means for your planning.
❌ Myth
"Medicare is free — I paid into it my whole career."
▾
✅ The Reality
You paid into Medicare Part A through payroll taxes — which covers hospital care. But Part B, which covers doctors, outpatient services, and most of what you'll actually use, costs $185/month or more in 2025 and increases with income-based surcharges. Add Part D and a Medigap supplement and most retirees pay $400–$700+/month in Medicare costs.
❌ Myth
"I'll figure out Medicare when I turn 65 — there's plenty of time."
▾
✅ The Reality
Because IRMAA surcharges are based on income from 2 years prior, decisions made at 63 directly affect what you pay at 65. Roth conversions, income sequencing, and tax-free income strategies need to be in place years before enrollment — not the week you sign up. Getting it wrong can cost $50,000+ over a 20-year retirement.
❌ Myth
"If I stay on my spouse's employer plan past 65, I'm covered and don't need Medicare."
▾
✅ The Reality
Staying on active employer group coverage (through you or your spouse's current job) is a valid reason to delay enrollment — but only if it's active employment, not COBRA or retiree coverage. COBRA does NOT qualify as creditable coverage for Medicare Part B. Miss this distinction and you face the lifetime late penalty.
❌ Myth
"I can always switch to a better plan later if Medicare Advantage doesn't work out."
▾
✅ The Reality
Switching from Medicare Advantage back to Medigap requires passing medical underwriting in most states — and with pre-existing conditions, you may be denied entirely or charged far more. The plan you choose at 65 is much harder to change than most people realize. Your initial decision carries permanent weight.
❌ Myth
"My Roth IRA won't affect my Medicare premiums — it's tax-free money."
▾
✅ The Reality
Roth IRA distributions and policy loans from properly structured life insurance are NOT counted toward IRMAA's income formula — this is one of their most powerful benefits. However, Roth conversions DO count as income in the year you convert, which can temporarily push you into a higher IRMAA bracket. Timing matters.
