The most common advice for Medicare on the CFP exam is to memorize what Parts A, B, C, and D cover. This advice is dangerously incomplete. The CFP Board tests your judgment on the financial consequences of a client's Medicare decisions, especially the costly, permanent penalties hidden in enrollment periods and income-related surcharges.
To pass Medicare questions on the CFP exam, you must master the Initial, Special, and General Enrollment Periods to avoid penalties, calculate IRMAA surcharges using a client's MAGI from two years prior, and analyze the trade-offs between Medigap (which you cannot have with Part C) and Medicare Advantage plans.
Key facts
- Official Body: CFP Board
- Exam Section: Risk Management and Insurance Planning (11% of exam)
- Core Topics: Medicare Parts A, B, C, D; Medigap; Enrollment Periods; IRMAA surcharges
- Key Thresholds (2026, illustrative): IRMAA surcharges begin for individuals with a 2024 MAGI over $103,000 and couples over $206,000.
- Exam Format: Multiple-choice questions, often presented as short client case scenarios.
- Pass Rate: The overall CFP exam pass rate is consistently between 60% and 65%, according to the CFP Board, underscoring the need to master every topic.
Why Does the CFP Exam Test Medicare So Deeply?
Medicare is the federal health insurance program for people aged 65 or older and certain younger individuals with disabilities. On the exam, however, it serves as a powerful test of a planner's ability to translate complex rules into actionable, financially sound advice.
The examiner won't ask you to simply define Part B. Instead, a question will present a client scenario and require you to identify the strategy that avoids lifelong penalties or minimizes lifetime costs.

They test your ability to:
- Navigate complex enrollment windows for clients who work past age 65.
- Integrate a client's past income (specifically, MAGI from two years ago) to determine their actual premium costs today.
- Advise on the critical, often irreversible choice between a Medigap supplement and a Medicare Advantage plan.
The biggest mistake candidates make is underestimating the timelines. They memorize the "what" but fail the questions that test the "when" and "how much." This isn't just about health insurance; it's about safeguarding a client's retirement from catastrophic costs and permanent penalties. Your ability to spot these issues is a direct test of your fiduciary duty.

What Medicare Rules and Traps Appear on the Exam?
Success on this topic comes from internalizing the system's financial levers. Let's dismantle the core concepts through the lens of common candidate misconceptions.
Myth 1: "I just need to memorize what A, B, C, and D cover."
This is the baseline, but it's not enough. The reality is the exam tests the financial decisions around these parts.
| Part | What It Covers | Key Exam Focus |
|---|---|---|
| Part A | Hospital Insurance (inpatient care, skilled nursing, hospice) | Usually premium-free with 40 quarters of work. Know that clients can buy into it if they don't qualify. |
| Part B | Medical Insurance (doctor visits, outpatient care, preventative services) | Has a monthly premium. This is where late enrollment penalties and IRMAA surcharges are most heavily tested. |
| Part C | Medicare Advantage (private plans that bundle A, B, and often D) | An alternative to Original Medicare. The exam tests network restrictions (HMO/PPO) vs. potential cost savings. |
| Part D | Prescription Drug Coverage (private plans) | Also has a monthly premium and is subject to IRMAA and late enrollment penalties. Focus on enrollment timing. |
Myth 2: "Everyone signs up at 65."
This assumption is a classic exam trap. The test will give you clients who are still working at 65 with employer coverage, creating a more complex decision. You must know the three enrollment periods cold.
- Initial Enrollment Period (IEP): The standard 7-month window around the 65th birthday (3 months before, the month of, and 3 months after).
- Special Enrollment Period (SEP): This is the exception the exam loves to test. If a client has creditable group health plan coverage from an employer (with 20+ employees), they can delay Part B without penalty. Their 8-month SEP begins when that employment or the group coverage ends, whichever is first.
- General Enrollment Period (GEP): For those who missed their IEP and do not qualify for an SEP. It runs from January 1 to March 31, with coverage starting July 1. This path almost always triggers penalties.
> ⚠️ Exam trap: > COBRA and retiree health plans are not considered creditable coverage for the purpose of a Special Enrollment Period. A client relying on COBRA after leaving their job must enroll in Part B during their IEP to avoid penalties. This is a subtle but critical distinction.
The Part B late enrollment penalty is 10% of the standard premium for each full 12-month period you could have had Part B but didn't have creditable employer coverage.
This penalty is for life.
Myth 3: "Medicare premiums are the same for everyone."
This is dangerously false and a major testing area. High-income clients pay more for Parts B and D through the Income-Related Monthly Adjustment Amount (IRMAA).
- Look-back Period: IRMAA is based on the client's Modified Adjusted Gross Income (MAGI) from two years ago. The exam will provide this figure (e.g., "For 2026 premiums, use the client's 2024 MAGI of $X"). Your job is to apply it correctly.
- Thresholds: Surcharges are tiered. For 2026, the first tier will likely apply to individuals with a 2024 MAGI over $103,000 and joint filers over $206,000.
- The Appeal: A newly retired client may have a much lower current income but will still pay premiums based on their higher working income from two years prior. You can file Form SSA-44 to appeal IRMAA based on specific life-changing events, such as marriage, divorce, death of a spouse, or a work stoppage/reduction.
Worked Example with Step-by-Step Solution
Let's apply these rules to a classic exam-style scenario.
> 💡 Worked example: > David and Sarah, both age 64, are meeting with you in January 2026. David plans to retire in June 2026, the month he turns 65. Sarah also turns 65 in June 2026 but will continue working full-time and maintain her employer's group health coverage, which covers David. Their 2024 joint tax return shows a MAGI of $250,000. > > They ask for guidance on their Medicare enrollment. Which of the following is the most appropriate advice?

This question combines timing, employer coverage, and IRMAA.
Step 1: Analyze David's Situation
David is retiring and losing employer coverage. He must enroll in Medicare.
- When? His Initial Enrollment Period (IEP) is from March to September 2026. He should enroll before June to ensure coverage begins on June 1.
- What? He needs Part A (premium-free) and Part B. He will also need to select a Part D plan or a Part C plan that includes drug coverage.
Step 2: Analyze Sarah's Situation
Sarah is continuing to work and has creditable group coverage.
- Does she have to enroll in Part B? No. Because she has creditable coverage, she qualifies for a Special Enrollment Period (SEP). She can delay Part B without penalty.
- Should she enroll in Part A? Yes. Part A is premium-free for most people and can coordinate with her employer plan. There is no reason to delay it.
Step 3: Calculate their Premiums and IRMAA
This is where points are won or lost.
- Look-back: Their 2026 premiums are based on their 2024 MAGI of $250,000.
- Threshold: This MAGI ($250,000) is above the joint filer threshold of $206,000.
- Impact: David will be subject to IRMAA surcharges on his Part B premium. If he enrolls in a Part D plan, that premium will also have an IRMAA surcharge. You must advise them to expect higher-than-standard premiums based on their income from two years ago.
Step 4: Formulate the Advice
The correct advice integrates all these points. David should enroll in Parts A and B during his IEP and select a drug plan, prepared for IRMAA-adjusted premiums. Sarah should enroll in Part A only and use her SEP to enroll in Part B without penalty when she eventually retires.
> ⚠️ Exam trap: > The most tempting wrong answer is to advise both David and Sarah to enroll in Parts A and B immediately. This seems "safe." It is incorrect because it forces Sarah to pay Part B premiums while she still has excellent employer coverage. It demonstrates a failure to understand the Special Enrollment Period, a critical concept for clients working past 65. The examiner wants to see if you can save your client money by correctly applying the rules.
How to Choose Between Medigap and Medicare Advantage
A frequent point of confusion, and therefore a prime testing area, is the choice between supplementing Original Medicare or replacing it.
| Feature | Medigap (Supplement) | Medicare Advantage (Part C) |
|---|---|---|
| What it is | Private insurance that pays after Original Medicare to cover gaps like deductibles and coinsurance. | A private plan that replaces Original Medicare. You get all Part A and B benefits through one plan. |
| Doctor Choice | You can see any doctor in the U.S. that accepts Medicare. No networks or referrals needed. | You are typically restricted to a network of doctors (HMO or PPO). May require referrals. |
| Cost Structure | Higher monthly premium but lower, more predictable out-of-pocket costs for services. | Lower (or $0) monthly premium but higher out-of-pocket costs (copays, coinsurance) when you use services. |
| Prescription Drugs | Does not include drug coverage. You must buy a separate Part D plan. | Most plans bundle in prescription drug coverage (MA-PD). |
The most important rule is that you cannot have both. A client with a Medicare Advantage plan cannot also have a Medigap policy. This is a fundamental choice a planner must help a client navigate.
How to Structure Your Medicare Study Plan
- Focus on Application: Spend 20% of your time on definitions and 80% working through scenarios. Use a whiteboard to map out timelines for different client situations: retiring at 65, working until 70, spouse with different age/work status.
- Connect to Other Topics: Medicare is not an island. It connects directly to Tax Planning (IRMAA is based on MAGI) and Retirement Planning (it's a major expense). Understanding how to calculate MAGI is essential, a topic covered in our deep dive on above-the-line tax deductions.
- Final Week Review: Create a one-page summary chart comparing Medigap and Medicare Advantage. Write down the three enrollment periods and the conditions for each. Drill the current year's IRMAA brackets. VoraPrep's adaptive question bank, with over 6,900 questions, can help you pinpoint and strengthen your remaining weak areas in the final days.
