How long you need to keep Medicare records depends on who is asking and what they might need to verify

The general rule is to keep Medicare records for at least three years after the person's death. The Centers for Medicare & Medicaid Services (CMS) and the Social Security Administration can request documentation during this window to confirm that bills were paid correctly, that the person was truly enrolled when services were provided, or that no overpayments were made. After three years, you can usually discard routine statements and explanation of benefits letters.

However, some records should be kept longer. If there is any chance of a Medicare audit, a billing dispute, or an estate settlement that involves medical debt, you may need to hold onto records for seven years or longer. The safest approach is to keep records until the estate is fully settled and any potential claims have passed their important date.

Key Takeaways

  • Keep Medicare records for at least three years after death to satisfy federal record-keeping rules.
  • If an audit, billing dispute, or estate claim is pending, keep all records until that matter is resolved.
  • Original documents like the Medicare card, enrollment letters, and proof of payment should be kept longer than routine statements.
  • You can safely discard duplicate statements and explanation of benefits letters after three years if no disputes are active.
  • Contact the Medicare beneficiary services line or the estate's attorney if you are unsure whether a specific record can be discarded.

Records to keep for at least three years

Routine Medicare paperwork falls into this category: monthly statements, explanation of benefits letters, premium payment receipts, and routine correspondence from Medicare. These documents prove what was billed, what was paid, and what the person's coverage was at any given time. If CMS or Social Security later questions a claim or a payment, these records let you show what actually happened.

Keep these records in a single folder or file, organized by year. You do not need to keep duplicates — if you have the same statement in paper and electronic form, one copy is enough. After three years with no disputes, you can shred or delete them.

Records to keep longer than three years

Some documents should stay in your files indefinitely or until the estate is closed. The Medicare card itself, enrollment confirmation letters, and any letters about changes in coverage (such as switching plans or losing coverage) are part of the permanent record. These prove when the person was enrolled and what their coverage included.

Keep all records related to a billing dispute, audit notice, or claim denial for as long as that matter is unresolved, plus three years after it closes. If the estate is still being settled or if there are unpaid medical bills, keep everything until the attorney or executor confirms the estate is finalized. Some states require executors to keep estate records for seven years.

If the person received Medicaid at any point in addition to Medicare, those records follow different rules — ask the state Medicaid office how long to keep them, as this varies by state.

What to do with records you no longer need

Do not straightforward throw Medicare records in the trash. They contain the person's name, Social Security number, dates of birth, and medical information. Shred paper documents or use a document destruction service. For electronic files, delete them permanently from your computer and empty the recycle bin, or use file-wiping software if you are concerned about recovery.

If you are storing records in the cloud or on a shared drive, make sure you have permission to delete them and that no other executor or family member still needs access. Consider taking a photo of key documents (the Medicare card, enrollment letters, proof of final payment) before you discard the originals, in case you need to reference them later.

When Medicare or Social Security asks for records

If you receive a letter from CMS, Social Security, or a Medicare contractor asking for documentation, do not discard anything until that request is resolved. Respond within the important date stated in the letter — usually 30 days — and keep copies of what you send. Even after you respond, keep the originals for at least three more years in case follow-up questions arise.

If you cannot find a record that was requested, write down what you remember about it (the date, the provider, the amount) and send that to the agency along with an explanation of why the original is not available. Many disputes can be resolved without the original document if you can show a reasonable account of what happened.

Records related to unpaid medical bills or estate claims

If the person died with unpaid medical debt, keep all records until the debt is resolved or the statute of limitations expires. In most states, creditors have three to six years to sue for unpaid medical bills, though this varies. An estate attorney can tell you the important date in your state.

If you are the executor and you are settling the estate, your attorney will advise you on how long to keep records. Some states require executors to keep all estate documents for seven years. Do not discard anything without checking with the attorney first.

How to organize records for straightforward reference

Create a straightforward system before you start sorting. Use a filing box or folder labeled with the person's name and the years covered. Organize by year, then by month if the volume is large. Keep a one-page index on top listing what is inside: "2023 Medicare statements," "2024 explanation of benefits," "enrollment letters 2020–2024," and so on.

If you are storing records digitally, use the same year-and-month naming system for files. Store them in a password-protected folder or encrypted drive. Write down where the records are stored and give that information to the executor or attorney so they know where to find them if needed.

Frequently Asked Questions

Can I throw away Medicare statements after one year?

No. Keep them for at least three years. If a billing question comes up, Medicare or the provider may need to see the original statement to confirm what was billed and paid. After three years with no disputes, you can discard them.

What if I lost some Medicare records before the person died?

Contact Medicare at 1-800-MEDICARE and explain what is missing. They can often retrieve copies of statements or claims from their system. If you cannot find a record that Medicare asks for, tell them what happened and provide what documentation you do have.

Do I need to keep the Medicare card after someone dies?

Yes, keep it for at least three years. It proves enrollment dates and the person's Medicare number, which may be needed if questions arise about claims or coverage. After three years, you can discard it unless a dispute is pending.

Who should I contact if I am not sure how long to keep records?

Call Medicare at 1-800-MEDICARE and describe the situation. If the estate is being settled, ask the executor's attorney. If there is an active dispute or audit, the letter you received will list a contact person to call.

What if the person had both Medicare and Medicaid?

Medicare records follow the three-year rule. Medicaid records vary by state. Contact your state Medicaid office to ask how long to keep those records — some states require seven years or longer.
