Medicare MSA Plans: How They Work and Who They Fit

A Medicare MSA plan is a Medicare Advantage (Part C) plan that pairs a high-deductible health plan with a medical savings account. Medicare pays the plan, and the plan deposits money into your account. You use that money for care until you meet the deductible, and then the plan pays. The catch is availability: very few areas have an MSA plan, and Oregon may not be one of them in a given year. Below you will find how the plans work, who can join, how the taxes work, and how to check what is offered where you live.
TL;DR
- A Medicare MSA plan is a consumer-directed Medicare Advantage plan with a high deductible and a deposit into a savings account.
- The plan deposits money into your account each year. You pay for care out of that account, then out of pocket, until you meet the deductible.
- Money left in the account stays there for future years. Withdrawals for qualified medical expenses are not taxed.
- MSA plans are offered in very few places. For 2026, one source reports they are available only in Wisconsin.
- If you live in Central Oregon, a local agent can check what is actually offered in Deschutes County and compare it with other options at no cost.

What a Medicare MSA plan is
Medicare MSA plans are a type of Medicare Advantage plan. According to Medicare.gov, they are consumer-directed plans that generally let you choose your health care services and providers, and they usually have no network of doctors or hospitals.
The plan has two parts:
- A high-deductible health plan. It starts paying for Medicare-covered services only after you meet a high yearly deductible.
- A medical savings account. Medicare gives the plan an amount each year, and the plan deposits it in the account for you.
You still pay your Part B premium. You are still in Medicare, with Original Medicare benefits delivered through the private plan. The difference is how you pay for care along the way.
How the deposit and deductible work
The plan puts the yearly deposit into your account at the start of the calendar year. If you join mid-year, it deposits in the first month your coverage starts. Both the deposit and the deductible are prorated based on when your enrollment begins.
The sequence looks like this:
- The deposit lands in your account.
- You pay for Medicare-covered care from the account.
- When the account runs dry, you pay out of pocket until you reach the deductible.
- After that, the plan begins covering costs.
CMS stresses that you should know both the deposit amount and the deductible amount before you enroll. The gap between the two is the amount you could pay yourself in a bad year.
A worked example with 2026 figures

One source reports that the maximum allowable MSA deductible is $18,100 in 2026, though plans can set a lower one. The same page describes the one plan it lists for 2026 as having a $4,000 deductible and a $1,750 deposit.
Here is what that means in practice. Say you have a year with $6,000 in covered care:
| Step | Amount |
|---|---|
| Deductible | $4,000 |
| Deposit in your account | $1,750 |
| Gap you pay out of pocket before coverage starts | $2,250 |
| Plan pays after the deductible is met | The covered costs above $4,000 |
With a quieter year, you might spend only part of the deposit, and the rest stays in the account. Plan terms change every year, so use this as an illustration of the mechanics, not a quote.
What the account can pay for
The account can pay for Medicare-covered costs before you meet the deductible. It may also pay for some other qualified medical expenses. Money left at year end stays in the account and may be used for health care in future years.
That rollover is the feature people like most. A person who stays healthy builds a cushion. A person who has a hospital stay faces the deductible.
Prescription drugs
An MSA plan cannot include drug coverage. CMS guidance says MSA enrollees must get Part D through a separate stand-alone drug plan.
Two details matter once you add one:
- You can use your MSA account to pay Part D copayments, and that spending counts toward your Part D out-of-pocket costs.
- Part D copayments do not count toward the MSA deductible.
So drug costs and the MSA deductible run on two separate tracks. If you take regular medications, look at how a Part D plan works in Bend and how drug tiers affect what you pay.
Who can enroll
You must have Medicare Parts A and B to join any Medicare Advantage plan, and MSA plans add their own limits. CMS enrollment guidance lists several situations that make a person ineligible for an MSA plan:
- Living in the U.S. fewer than 183 days during the year the election takes effect
- Being enrolled in the Federal Employees Health Benefits program, or being eligible for VA or Department of Defense coverage
- Being eligible for both Medicare and Medicaid premium or cost-sharing help
- Receiving hospice benefits
- Having other health coverage that pays all or part of the MSA deductible
The residency rule is in federal regulation: you must give assurances satisfactory to CMS that you will live in the U.S. at least 183 days in the election year.
The other-coverage rule catches many people. If you have retiree coverage or a supplement that pays toward the deductible, an MSA plan generally will not work alongside it.
When you can enroll
Like other Medicare Advantage plans, MSA plans follow the yearly fall window. One source puts the switching period at October 15 to December 7 each year, with coverage starting the following January. If you are newly eligible or have a life change, see our guide to Medicare special enrollment.
Tax rules
The MSA is designed to be tax-advantaged, but it comes with paperwork. CMS says withdrawals for qualified medical expenses are not taxed, while withdrawals for anything else are subject to income tax plus an additional penalty tax. CMS also says enrollees must file Form 1040 and Form 8853 each year to report withdrawals.
IRS Publication 969 is the document that defines qualified medical expenses and sets the current penalty rate. Read the current edition, or ask your tax preparer, before you take money out for anything other than medical care. Keep receipts for every withdrawal.
Are MSA plans available in Oregon?
This is the question that matters most for readers near Bend. MSA plans are offered by very few insurers, and the list changes each year. One 2026 source reports Wisconsin as the only state with an MSA plan that year. Another report, published in 2024, said only one company still offered MSA plans, but treat that as background and not as a current list.
What you can do:
- Use the plan finder at Medicare.gov and filter for Medicare Advantage plans with your ZIP code. If an MSA plan is not listed, none is offered where you live.
- Call 1-800-MEDICARE.
- Ask a local agent to check the current Deschutes County plan list for the coming year.
If no MSA is offered here, you still have good ways to manage cost and risk, covered below.
Alternatives if you want predictable costs
People look at MSA plans for lower premiums or more freedom to choose doctors. Other routes can serve those goals in Central Oregon:
| Goal | Option to look at |
|---|---|
| See any doctor who accepts Medicare | Original Medicare with a Medigap plan |
| Lower monthly premium with a set network | A Medicare Advantage plan, after you confirm your doctors are in network |
| Help with a chronic condition | A C-SNP plan if you qualify |
| Cover costs Medicare does not | Supplemental plans such as hospital indemnity, critical illness and cancer |
| Dental and vision | Dental coverage and vision coverage |
If you are already on a Medigap plan and paying more than you need to, Oregon’s birthday rule may let you switch without a health screening. We can walk you through it.
Is an MSA plan a fit? Questions to ask
If an MSA plan is offered where you live, the decision comes down to a few points:
- Could you cover the gap? The difference between the deductible and the deposit is money you may have to pay yourself in a year with big medical bills.
- Do you have other coverage? Retiree, VA, TRICARE or FEHB coverage can make you ineligible.
- Are your drugs covered? You need a separate Part D plan, so price it alongside the MSA.
- Are you comfortable with tax reporting? Annual forms and receipts are part of the deal.
- Do you spend part of the year abroad? The 183-day rule applies.
Our perspective
We meet many people in Central Oregon who first ask about MSA plans because they have heard about a savings account paired with Medicare. The idea is appealing: keep what you do not spend.
Our approach is education first. Before you choose any plan, you should know the deposit, the deductible, the doctors you see and the drugs you take. We start there, and we check what is truly available in Deschutes County for the year ahead.
Our consultations are free, in person or remote. We are a local agency, not a call center, and we walk through Parts A, B, C and D and the deadlines that go with them, so you can choose with confidence.

FAQ
What is a Medicare MSA?
A Medicare MSA is a Medicare Advantage plan that combines a high-deductible health plan with a savings account. The plan deposits money in the account each year, and you use it for care until the deductible is met. Unused money stays in the account.
Can I use the account for prescriptions?
Yes, you can use it to pay Part D copayments if you have a separate drug plan. An MSA plan does not include drug coverage itself, and those copayments do not count toward the MSA deductible.
Is the money in a Medicare MSA taxed?
Withdrawals for qualified medical expenses are not taxed. Withdrawals for other purposes are taxed and carry an additional penalty. You report withdrawals each year on IRS forms, so ask your tax preparer about your situation.
Can I get an MSA plan in Oregon?
That depends on what insurers offer in your county for the year. Check the Medicare.gov plan finder with your ZIP code, or ask us to check Deschutes County for you.
