Planning for One of the Largest and Least Predictable Retirement Expenses
By the end of this lesson, you’ll understand:
Healthcare is often one of the largest expenses in retirement, and one of the hardest to predict, since it depends heavily on individual health, longevity, and circumstances that are genuinely difficult to know in advance.
Many retirees are also surprised to learn that Medicare, while broad, doesn’t cover every healthcare cost, understanding the gaps is as important as understanding the coverage itself.
Medicare is a federal health insurance program, generally available starting at age 65, regardless of whether you’re still working or already retired. Some people become eligible earlier due to specific disabilities or health conditions.
Enrollment generally isn’t automatic for everyone, depending on your situation, you may need to actively sign up during a specific enrollment window, and missing that window can result in a permanent late enrollment penalty on certain parts of coverage. Confirm your specific enrollment timeline with Medicare directly as you approach 65.
Medicare is divided into several parts, each covering different types of care.
| Part | What It Generally Covers |
|---|---|
| Part A | Hospital care, skilled nursing facility care, and some home health care |
| Part B | Doctor visits, outpatient care, preventive services, and medical equipment |
| Part C (Medicare Advantage) | A private-plan alternative that bundles Parts A and B, often including Part D |
| Part D | Prescription drug coverage |
Part A is often available with no monthly premium for those with sufficient work history, while Part B generally involves an ongoing monthly premium. Medicare Advantage (Part C) and Part D plans are offered through private insurers and vary in cost and coverage, which makes comparing specific plans directly worthwhile rather than assuming they’re interchangeable.
This is one of the most commonly misunderstood parts of retirement healthcare planning. Original Medicare generally does not cover, or covers only very limited amounts of:
Long-term custodial care in particular can be one of the largest uncovered healthcare-related expenses in retirement, which is why some people separately consider long-term care insurance or other planning strategies specifically for this gap.
Because Original Medicare doesn’t cover every cost, many retirees use additional coverage:
Choosing among these options depends on your health needs, budget, and preferences, and is worth reviewing carefully, ideally with a Medicare counselor or financial professional, rather than defaulting to whatever option seems simplest.
Since Medicare generally begins at 65, anyone retiring earlier needs a plan to cover the gap. Common approaches include:
This gap period can be expensive, and is worth factoring explicitly into any plan for retiring before 65, rather than assuming it will simply work itself out.
Medicare has an annual open enrollment period during which coverage can be reviewed and changed. Worth reviewing each year:
Healthcare needs and plan offerings both change over time, which is why this is worth an annual review rather than a decision made once and left alone.
James retired at 63, two years before Medicare eligibility. He initially assumed he’d simply purchase whatever health insurance was cheapest to bridge the gap, without comparing options carefully.
After reviewing COBRA continuation costs against marketplace plan options, he found a marketplace plan that fit his budget better while still covering his ongoing prescriptions.
At 65, James enrolled in Medicare during his eligibility window, added a Part D prescription drug plan, and purchased a Medigap policy to help cover the out-of-pocket costs Original Medicare left behind. He now reviews his coverage every year during open enrollment to confirm it still fits his needs.
Gaps like routine dental, vision, hearing, and long-term custodial care catch many retirees off guard.
Late enrollment in certain parts of Medicare can result in a permanent penalty added to future premiums.
Retiring before Medicare eligibility without a coverage plan can lead to an expensive and stressful scramble.
A plan that fit well one year may not fit as well the next, as costs, coverage, and personal health needs change.
Medicare is free.
While Part A is often premium-free for those with sufficient work history, Part B, Part D, and supplemental coverage generally involve ongoing costs.
Medicare covers long-term nursing home care.
Original Medicare generally covers only limited skilled nursing care under specific conditions, not extended custodial long-term care.
I don’t need to think about Medicare until I actually turn 65.
Enrollment windows and potential penalties mean it’s worth understanding the process before you’re actually eligible, not after.
All Medicare Advantage and Part D plans are basically the same.
These plans vary significantly in cost, covered medications, and included providers, which makes comparing specific plans worthwhile.
It depends on your specific situation, including the size of your employer and your current coverage. This is worth confirming directly with Medicare or your employer’s benefits office to avoid a coverage gap or penalty.
In many cases yes, with the two coordinating on which pays first for a given claim, though the specifics depend on your former employer’s plan.
Generally, Medicare Advantage plans may have lower premiums but more restricted provider networks, while Original Medicare with a Medigap policy generally offers broader provider access at a different cost structure. The right choice depends on your specific health needs and preferences.
This varies significantly by individual health and location, and published estimates are widely available as general reference points, though your own situation should be estimated individually as part of the retirement spending exercise covered earlier in this course.
This depends on your health, family history, assets, and risk tolerance for this specific type of expense. It’s a decision worth discussing with a financial professional, given how significant uncovered long-term care costs can become.
If you’re within a few years of 65, research your Medicare enrollment window this month and confirm the specific date it applies to you.
If retirement before 65 is part of your plan, use this same time to research your options for covering the gap until Medicare eligibility.
You now understand one of retirement’s largest expenses. The next lesson addresses a different kind of planning: making sure your retirement accounts go to the right people.
In the next lesson, you will learn:
Healthcare planning protects you during retirement. Beneficiary planning protects the people who matter to you afterward.
