What a Medicare Savings Account Does
A Medicare Savings Account (MSA) is a type of health insurance plan that pairs a high-deductible Medicare Advantage plan with a special savings account that Medicare funds for you. The account holds money that you use to pay your deductible, copayments, and coinsurance before your insurance kicks in. Unlike a Health Savings Account (HSA) that you control yourself, Medicare deposits the money into your MSA account each year, and you draw from it as you receive care.
The trade-off is straightforward: you accept a higher deductible than you would with a standard Medicare Advantage plan, but Medicare puts money into your account to help you cover it. If you do not spend all the money in a given year, it rolls over to the next year—you do not lose it.
MSAs are available only through Medicare Advantage plans, not through Original Medicare (Parts A and B). They are relatively uncommon; only a handful of insurers offer them in any given year, and availability varies by region.
Key Takeaways
- Medicare deposits money into your MSA account each year; you do not contribute your own funds or manage the account yourself.
- You use the account balance to pay your deductible and cost-sharing amounts before your insurance coverage begins.
- Unused money rolls over year to year, so you build a balance over time if you do not spend it all.
- MSA plans have higher deductibles than standard Medicare Advantage plans, but the Medicare deposit is meant to offset that difference.
- Only a few insurers offer MSAs, and they are not available in all regions.
How Medicare Funds Your Account Each Year
At the start of each calendar year, Medicare deposits a fixed amount into your MSA based on your plan and your age. The amount varies by insurer and plan design, but it is typically between $500 and $2,000 per year. You do not apply for this money or take any action—it appears automatically if you are enrolled in an MSA plan.
The deposit is meant to cover a portion of your annual deductible. For example, if your plan has a $3,000 deductible and Medicare deposits $1,500, you are responsible for the first $1,500 of covered services out of pocket, and then the $1,500 in your account covers the next portion.
The amount Medicare deposits does not change based on how much you actually spend. If you use very little medical care and do not spend down your account, the unused balance stays in the account and carries forward to the next year. There is no "use it or lose it" rule.
When and How You Use the Money
You use your MSA balance whenever you receive a covered service that requires you to pay a deductible, copayment, or coinsurance. When you go to a doctor, hospital, or pharmacy, you present your insurance card as usual. The provider bills your plan, and your plan tells you what you owe out of pocket.
You then pay that amount from your MSA account. Most plans issue you a debit card linked to the account, so you can pay at the point of service without having to file a claim or wait for reimbursement. Some plans require you to pay out of pocket first and then request reimbursement from the account, but debit cards are more common.
Once your out-of-pocket costs reach your plan's out-of-pocket maximum for the year, your insurance covers 100 percent of additional covered services. Your MSA balance does not affect this limit—it is simply the tool you use to pay the costs that count toward the maximum.
What Happens to Money You Do Not Spend
Unlike a flexible spending account (FSA) through an employer, an MSA has no annual deadline. Money you do not spend in a given year rolls over automatically to the next year. Over time, if you are relatively healthy and do not use much medical care, your MSA balance can grow substantially.
This rollover feature makes MSAs appealing to people who expect to have low medical expenses in the near term but want to build a cushion for future years. A 55-year-old who stays healthy might accumulate several years' worth of deposits by the time they reach 65 or older, when medical costs typically rise.
If you switch to a different Medicare plan or lose your MSA coverage, you keep the balance in your account. However, you can only use it to pay Medicare-related out-of-pocket costs. You cannot withdraw the money for non-medical expenses.
The Deductible and Out-of-Pocket Maximum
MSA plans have higher deductibles than most Medicare Advantage plans. A typical MSA plan might have a $3,000 annual deductible, whereas a standard Medicare Advantage plan might have a $0 to $500 deductible. The trade-off is that Medicare's annual deposit into your account is designed to offset some or all of that higher deductible.
Your out-of-pocket maximum—the most you will pay in a year for covered services—also tends to be higher on an MSA plan. This maximum typically ranges from $5,000 to $7,000 per year, depending on the plan. Once you reach this limit, your insurance covers 100 percent of additional covered services for the rest of the year.
The MSA deposit counts toward your deductible but not toward your out-of-pocket maximum. This means if you have a $3,000 deductible and a $1,500 MSA deposit, you need to pay $1,500 out of pocket before insurance begins to cover costs. After that, copayments and coinsurance continue to count toward your out-of-pocket maximum.
Who Should Consider an MSA Plan
MSA plans work best for people who expect relatively low medical expenses in the near term and want to build savings for future healthcare costs. If you are healthy, do not take many medications, and do not see specialists frequently, the higher deductible may not cost you much, and you benefit from the annual Medicare deposit building up over time.
MSA plans are less suitable if you have chronic conditions, take multiple medications, or see doctors regularly. The higher deductible means you will pay more out of pocket for each visit and prescription, and the MSA deposit may not cover enough to make up the difference.
You should also consider whether an MSA plan is actually available in your area. Because few insurers offer them, you may not have the option regardless of whether it would suit your situation. Check your plan options during Medicare's annual enrollment period (October 15 to December 7 each year) to see if any MSA plans are offered where you live.
How MSAs Differ from HSAs and FSAs
An MSA is often confused with an HSA (Health Savings Account) because both involve a savings account paired with a high-deductible health plan. The key difference is who controls the money and who funds it. With an HSA, you contribute your own money (or your employer does), and you manage the account. With an MSA, Medicare funds the account automatically, and you simply draw from it.
MSAs are also different from FSAs (Flexible Spending Accounts), which are employer-sponsored accounts that operate on a "use it or lose it" basis—money not spent by the end of the year is forfeited. MSA money rolls over indefinitely, so there is no penalty for not spending it.
If you are under 65 and have employer health insurance, you may have access to an HSA. Once you turn 65 and enroll in Medicare, you can no longer contribute to an HSA, but you can continue to use money already in the account for Medicare-related expenses. An MSA is the Medicare equivalent of an HSA.
Frequently Asked Questions
Can I use my MSA balance for prescriptions and dental care?
You can use your MSA for prescription drugs covered by your Medicare Advantage plan's formulary, and the balance counts toward your deductible and out-of-pocket maximum. Dental and vision care are generally not covered by Medicare Advantage plans, so you cannot use your MSA for those services unless your specific plan includes dental or vision coverage.
What happens to my MSA if I switch plans or move to Original Medicare?
You keep the balance in your account, but you can only use it to pay Medicare-related out-of-pocket costs. If you switch to Original Medicare, you can use the balance for Part A and Part B cost-sharing. If you switch to a different Medicare Advantage plan, you can use it for that plan's deductible and copayments.
Does the MSA deposit count toward my out-of-pocket maximum?
No. The deposit counts toward your deductible, but once your deductible is met, additional copayments and coinsurance count toward your out-of-pocket maximum. The MSA deposit itself does not reduce the amount you need to spend to reach your out-of-pocket maximum.
Can I withdraw money from my MSA for non-medical expenses?
No. MSA funds can only be used to pay Medicare-related out-of-pocket costs. Withdrawing money for other purposes is not permitted under Medicare rules.
How do I know if an MSA plan is available where I live?
During Medicare's annual enrollment period (October 15 to December 7), you can view all available plans in your area on Medicare.gov or by calling 1-800-MEDICARE. Search for plans in your ZIP code, and filter for Medicare Advantage plans to see if any MSA options appear.
