5 Medicare Mistakes That Could Cost You
Medicare can be confusing.
There are enrollment windows, different types of coverage, prescription drug plans, provider networks, income-related costs, and plenty of important dates to keep track of.
And unfortunately, some Medicare mistakes can be expensive.
The good news?
Many common Medicare mistakes can be avoided with a little planning and the right information.
At Life and Med: Medicare Resource Center, we want to make Medicare easier to understand. So let’s look at five common Medicare mistakesāand what you can do to avoid them.
šØ Mistake #1: Waiting Too Long to Enroll
Turning 65 is exciting.
Medicare paperwork? Not so much. š
One of the biggest mistakes people make is assuming they can enroll in Medicare whenever they want without consequences.
Your Initial Enrollment Period generally gives you a seven-month window surrounding your 65th birthday to enroll.
If you don’t enroll in Part B when you’re supposed to and don’t have qualifying coverage through current employment, you could face a late enrollment penalty.
Part D prescription drug coverage has its own late enrollment penalty if you go without creditable prescription drug coverage for a certain period.
š” How to Avoid It
If you’re approaching 65:
- Know when your Initial Enrollment Period begins and ends.
- Find out whether your current employer coverage affects when you should enroll.
- Don’t assume COBRA or retiree coverage works the same way as active employer coverage.
- Keep documentation about your current health coverage.
- Don’t wait until the last minute to figure everything out.
Turning 65? Start the Medicare conversation early!
š Mistake #2: Choosing a Plan Without Looking at the Details
A plan can look great on paper and still not be the right fit for your particular situation.
Before choosing coverage, look beyond the monthly premium.
Consider:
š©āāļø Your doctors
š Your prescriptions
š„ Your preferred hospitals
š° Your potential out-of-pocket costs
š Where you live and travel
š The plan’s rules and benefits
Medicare Advantage and Original Medicare work differently, so understanding how each option operates is important.
š” How to Avoid It
Make a list of your:
- Current doctors
- Prescription medications
- Preferred hospitals
- Healthcare needs
- Travel plans
- Expected healthcare expenses
Then compare the coverageānot just the price tag.
š Mistake #3: Choosing a Plan Once and Never Looking at It Again

Here’s a big one:
Your Medicare plan can change.
Even if you loved your plan this year, that doesn’t necessarily mean everything will be exactly the same next year.
Changes can include:
š Prescription drug coverage
š° Premiums
š©āāļø Provider networks
š„ Copayments and coinsurance
𦷠Dental benefits
š Vision benefits
š³ Over-the-counter allowances and other extras
That’s why your Annual Notice of Change (ANOC) is important.
It explains changes to your plan for the upcoming year.
š” How to Avoid It
When your ANOC arrives, don’t toss it into the āI’ll read that laterā pile.
Take a look at:
- What’s changing?
- Are your medications still covered?
- Are your doctors still participating?
- Did your costs change?
- Are the benefits you use still included?
Then compare your options during Medicare’s Annual Enrollment Period if appropriate.
A five-minute review could uncover an important change.
š Mistake #4: Missing a Special Enrollment Period
Life doesn’t always follow Medicare’s calendar.
You might retire, move, lose employer coverage, lose Medicaid eligibility, or experience another qualifying life event.
Some of these situations may give you a Special Enrollment Period (SEP) that allows you to make certain Medicare coverage changes outside the normal enrollment periods.
But here’s the catch:
Special Enrollment Periods have rules and deadlines.
š” How to Avoid It
If something major changes in your life, don’t assume you’ll have to wait until the next Annual Enrollment Period.
Ask:
āDoes this life change give me a Special Enrollment Period?ā
And if it does, find out exactly when that enrollment window starts and ends.
Keep documentation of important dates, including when employer coverage ends or when you move.
š° Mistake #5: Forgetting About IRMAA
IRMAA sounds like somebody’s great-aunt.
It’s actually the Income-Related Monthly Adjustment Amount. š
IRMAA is an additional amount that some higher-income Medicare beneficiaries pay on top of their standard Part B and Part D premiums.
And here’s the part that surprises many people:
Medicare generally uses tax-return information from two years earlier to determine IRMAA.
So a change in income today may not immediately show up in your Medicare premiums.
š” How to Avoid Surprises
If you’re approaching retirement or experiencing a major financial change, understand how your income could affect Medicare costs.
Certain life-changing events may allow you to ask Social Security to reconsider an IRMAA determination.
If you believe your income has dropped because of a qualifying life-changing event, you may be able to request a reconsideration.
For complicated tax and retirement-income questions, a qualified financial or tax professional can help you understand your options.
