As the end of the year approaches, Medicare may be showing up on your to-do list.
Maybe you've received a notice about changes to your coverage. Perhaps you're reviewing prescription drug costs or wondering whether your current plan will still meet your needs next year.
And somewhere in the middle of all that paperwork, you may also be wondering why your Medicare premiums are higher than expected.
It's easy to assume these questions are all connected.
But there's an important distinction worth understanding: Medicare coverage decisions and income-related premium adjustments are two different matters.
Knowing which one you're dealing with can help you ask better questions and avoid overlooking something important.
Medicare Enrollment Is About Your Coverage
Medicare's annual Open Enrollment Period generally runs from October 15 through December 7.
During this window, eligible beneficiaries can make certain changes to Medicare Advantage and Part D prescription drug coverage for the following year.
This is an opportunity to review questions such as:
Will my doctors and preferred hospitals still be covered or in-network?
Are my prescriptions covered, and have the costs changed?
What will I pay in premiums, deductibles, and out-of-pocket expenses?
Does my current coverage still fit my healthcare needs?
Even if you're satisfied with your current coverage, reviewing the changes can be worthwhile.
The goal isn't necessarily to switch plans. It's to understand what you're keeping, or what you might want to change.
IRMAA Is About Income and Medicare Premiums
IRMAA stands for Income-Related Monthly Adjustment Amount.
It's an additional amount that some Medicare beneficiaries pay for Part B and Part D based on their income.
Unlike choosing Medicare coverage, IRMAA generally isn't determined by which Medicare Advantage or prescription drug plan you select.
Social Security typically uses information from your federal tax return from two years earlier to determine whether an income-related adjustment applies.
That means financial decisions made in an earlier year may affect what you're paying for Medicare today.
For example, a Roth conversion, investment sale, or unusually high-income year may increase the income used in an IRMAA determination.
And if your income has since decreased, your current financial circumstances may look quite different from the tax return Social Security is using.
Certain qualifying life-changing events may allow you to request a new IRMAA determination. But not every income change qualifies, and an unusually high-income year doesn't automatically create an appeal opportunity.
That's why it's important to understand the circumstances before assuming an adjustment can be changed.
Why the Distinction Matters
Imagine you're reviewing your Medicare coverage for next year.
You notice that your premiums are higher than you expected, so you begin looking at other coverage options.
But what if part of that higher cost is an income-related adjustment?
Changing coverage may affect certain plan costs and benefits, but it doesn't automatically remove an IRMAA adjustment.
And the reverse is also true: reviewing an IRMAA determination doesn't replace the need to evaluate your coverage.
These are separate decisions that may require different conversations.
For Medicare coverage questions, Medicare, a State Health Insurance Assistance Program (SHIP) counselor, or a qualified coverage professional can help you understand your options.
For IRMAA questions, Social Security administers the determination and any applicable reconsideration process.
And for questions about how retirement income, taxes, and financial decisions may affect future Medicare costs, your financial advisor and tax professional can help you look at the bigger picture.
A Little Preparation Can Make a Big Difference
You don't need to become a Medicare expert to prepare for these conversations.
Start by reviewing your current coverage and any notices you've received about next year.
Then take a look at your Medicare premium information. If an income-related adjustment applies, identify which tax year was used and whether your income has changed since then.
Gather any relevant tax returns, Medicare notices, and documentation of significant financial changes.
Most importantly, write down the questions you haven't answered.
You don't need to resolve everything at once. You just need to know what deserves attention and who can help.
And if you're wondering how your retirement income decisions, taxes, and Medicare-related costs fit into your overall financial plan, we'd welcome a conversation.
