How long you should keep Medicare statements depends on what you might need them for, but three years is the minimum, six years is safer if you deduct medical expenses, and five years or more is essential if long-term care Medicaid is a possibility. The longest deadline that applies to your situation is the one that governs.
The Retention Periods That Actually Apply to You
There is no single answer because several deadlines overlap. Work through each one and keep your statements until the last one passes.
Three Years for Basic Tax Protection
The IRS can assess additional tax within three years after your return was due or filed, whichever is later.1Internal Revenue Service. Time IRS Can Assess Tax If you claim medical deductions, your Medicare Summary Notices (MSNs) and Explanation of Benefits (EOB) statements are what the IRS would want to see. Three years is the floor.
Six Years If Income Could Be Questioned
If you underreport gross income by more than 25%, the assessment window extends to six years.2Internal Revenue Service. Topic No. 305, Recordkeeping That can happen more easily than people expect once retirement distributions, investment gains, or side income enter the picture. If you file a fraudulent return, there is no time limit at all. Six years after the tax year is a solid target for most Medicare beneficiaries who itemize medical deductions.
Until Any Appeal Is Fully Resolved
If you disagree with how a claim was processed under Original Medicare, you have 120 calendar days from receipt of the initial determination to request a redetermination. Receipt is presumed five calendar days after the date printed on the MSN.3eCFR. 42 CFR 405.942 – Time Frame for Filing a Request for a Redetermination For Medicare Advantage plans, the initial appeal deadline is shorter: 65 days from the date on the denial notice.4Medicare.gov. Appeals in Medicare Health Plans
Appeals do not always end at the first level. Original Medicare has five levels of appeal, and a case can stretch over years as it moves through reconsideration, an administrative law judge hearing, the Medicare Appeals Council, and federal court.5Medicare.gov. Appeals in Original Medicare Keep every statement connected to a disputed claim until the dispute is fully resolved and no further appeal is possible.
Through Your State’s Medical Debt Statute of Limitations
The statute of limitations on medical debt varies by state, generally ranging from three to ten years. If a provider or collection agency contacts you about an old balance, your MSN or EOB is often the fastest proof that a charge was already paid or that the amount is wrong. Holding the original statement prevents unnecessary payments on bills that were legitimately resolved.
Five Years for Medicaid Long-Term Care Planning
This is the retention period most people overlook, and it can be the most consequential. When you apply for Medicaid to cover long-term care such as a nursing home or assisted living, Medicaid reviews your financial history for the previous 60 months. This look-back period checks whether you transferred assets for less than fair market value in order to qualify. Violations trigger a penalty period during which Medicaid will not pay for your care.
Detailed records of healthcare spending, including your Medicare statements, help demonstrate that money spent during that window went to legitimate medical expenses rather than improper transfers. If you are over 60, or have any reason to think you might need Medicaid-funded long-term care within the next several years, five years of records is the minimum.
Indefinitely for Chronic Conditions and Major Events
For major medical events, chronic conditions, or long treatment histories, consider keeping statements indefinitely. These records build a continuous timeline of care that can matter when you switch providers, apply for disability benefits, or need to show a treatment pattern to a new specialist. Digital storage makes this practical at almost no cost.
Review Each Statement Before You File It
Keeping statements only helps if you read them. Reviewing your MSN or EOB when it arrives is one of the most effective ways to catch billing errors early, and it is your first line of defense against fraud.
Compare each statement against your own records. Did you see that provider on the dates listed? Did you receive the services described? Were you billed for equipment you never got? A charge for a service you never received is the most common sign that something is wrong. Duplicate charges for the same visit and inflated procedure codes, such as a simple office visit billed as a comprehensive exam, are also worth flagging.
If something looks wrong, start by calling the provider’s billing office, because many errors are simple coding mistakes that can be corrected. If you suspect actual fraud, report it to the HHS Office of Inspector General at 1-800-HHS-TIPS (1-800-447-8477) or online through that office.6Office of Inspector General. Submit a Hotline Complaint
Using Statements at Tax Time
If you itemize, you can deduct medical and dental expenses that exceed 7.5% of your adjusted gross income.7Internal Revenue Service. Topic No. 502, Medical and Dental Expenses For many beneficiaries with significant out-of-pocket costs, this deduction is meaningful. Your MSNs and EOBs document what you paid in deductibles, copayments, and coinsurance across the year.
The IRS expects you to keep records supporting your deduction but does not want you to send them with your return.8Internal Revenue Service. Publication 502 (2025), Medical and Dental Expenses Hold them in case of audit: three years at a minimum, six if your income could be questioned.1Internal Revenue Service. Time IRS Can Assess Tax
Storing and Eventually Disposing of Statements
A filing system does not need to be elaborate. For paper statements, a folder for each calendar year works. Keep MSNs and EOBs separate from provider bills so you can compare them side by side. Label folders by year and by type of coverage (Original Medicare, Part D, or the name of your Advantage plan).
Scanning paper statements and saving them digitally is worth the effort. Store them on an encrypted external drive or a reputable cloud service with two-factor authentication turned on. Digital copies are searchable and easy to share with a provider, tax preparer, or attorney. Back up your files in at least two locations so a single hard drive failure will not wipe out years of records.
Switching to electronic MSNs through your Medicare.gov account eliminates the paper problem. You sign in with ID.me, CLEAR, or Login.gov, and your MSNs are available for any month a claim was processed.9Medicare. Go Digital
When you dispose of old statements that have passed all relevant retention periods, shred paper copies. These documents contain your name, Medicare number, dates of service, and diagnoses. For digital files, use a secure deletion tool rather than dragging files to the trash.
Keeping Records After a Beneficiary Dies
Families and estate executors should not rush to discard a deceased beneficiary’s Medicare statements. Under HIPAA, a decedent’s individually identifiable health information remains protected for 50 years after death, and the personal representative of the estate has the right to access and manage those records during that period.10U.S. Department of Health and Human Services. Health Information of Deceased Individuals
Practically, keep a deceased person’s Medicare statements for at least three to six years to cover final tax filings, outstanding provider bills, and estate settlement disputes. If the estate involves Medicaid estate recovery, where the state seeks reimbursement for long-term care costs, those records become critical for verifying what was actually spent and owed. Hold them until the estate is fully closed and all claims periods have expired.
