Minnesota Medical Records Retention Requirements: How Long Providers Must Keep Patient Records

General Retention Periods

Minnesota does not set a single universal rule for Patient Medical Record Retention across all settings. Retention depends on your facility type and any Licensed Healthcare Provider Requirements issued by your professional board, plus federal program overlays and HIPAA’s documentation rule. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))

What most providers should account for

• HIPAA: The Health Insurance Portability and Accountability Act (HIPAA) does not mandate how long you keep clinical records, but it does require you to keep required privacy/security documentation for six years from creation or last effective date. ([hhs.gov](https://www.hhs.gov/hipaa/for-professionals/faq/580/does-hipaa-require-covered-entities-to-keep-medical-records-for-any-period/index.html?utm_source=openai))
• Malpractice exposure: Minnesota’s statute of limitations for medical malpractice actions is four years; your policy should ensure records remain available for at least this window and be extended under any litigation hold. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/cite/541.076?utm_source=openai))
• Board rules: Examples of Licensed Healthcare Provider Requirements include dentists (retain adult records at least seven years beyond last treatment; for minors, seven years past age 18) and alcohol and drug counselors (retain for seven years after last service; minor clock starts at 18). ([revisor.mn.gov](https://www.revisor.mn.gov/rules/pdf/3100/2024-07-24%2015%3A13%3A49%2B00%3A00?utm_source=openai))
• Program overlays: Certain federally regulated settings, such as rural health clinics, must keep patient health records at least six years. ([law.cornell.edu](https://www.law.cornell.edu/cfr/text/42/491.10?utm_source=openai))
• Minors: Minnesota laws and board rules commonly delay the retention “clock” until the patient reaches the age of majority; verify the specific rule that applies to your setting. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))

Hospital Medical Records Retention

Minnesota Statutes Section 145.32 creates a two-tier scheme for hospitals: portions of the chart designated as the “individual permanent medical record” must be kept permanently (the term is defined by rule and explicitly includes outpatient diagnostic and lab results). Other portions may be destroyed after seven years. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))

For minors, hospitals must retain records for seven years or until the patient reaches the age of majority, whichever occurs later. Clinical Record Preservation may be accomplished by photographic film or electronic imaging under Section 145.30. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))

Nursing Home Clinical Records

Nursing homes must preserve each resident’s clinical record for at least five years following discharge or death. Current residents’ records must be stored on site, and off-site archives must be retrievable within one working day. ([revisor.mn.gov](https://www.revisor.mn.gov/rules/4658.0470/))

Medical Cannabis Patient Records

Medical cannabis manufacturers must maintain, for at least five years, complete records that include the date of each sale or distribution, the registration number of all patients, product details, pricing, inventory, and related quality records. Certifying practitioners and clinics should retain patient charts under the rules that govern their profession and HIPAA’s documentation rule. ([law.cornell.edu](https://www.law.cornell.edu/regulations/minnesota/Minn-R-4770-1600))

Withdrawal Management Program Records

Withdrawal management programs must keep a signed, dated patient record on the premises and protect it against loss and unauthorized disclosure. Retention and storage follow Subdivision 245A.041 Retention: at minimum, service recipient records are kept five years after discharge; personnel and administrative records also carry five-year minimums, with longer retention when a contested case is pending. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/cite/245F/pdf))

Government Records Management

If you are a public (government-run) provider, the Minnesota Official Records Act (Section 15.17) requires you to make and preserve official records. Destruction is governed by the state’s Records Management Statute (section 138.17), which requires an approved records retention schedule and prohibits destroying records except as scheduled and authorized. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/cite/15.17/pdf?utm_source=openai))

Legal Compliance for Retention

How to align your policy

• Map state-specific rules to your setting (e.g., Minnesota Statutes Section 145.32 for hospitals; Minnesota Rules 4658.0470 for nursing homes; board rules for clinicians such as dentists; and Chapter 245F with Section 245A.041 for withdrawal management programs). ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))
• Layer federal requirements, such as HIPAA’s six-year documentation rule and any program-specific federal retention (for example, rural health clinics’ six-year requirement). ([ecfr.io](https://ecfr.io/Title-45/Section-164.530?utm_source=openai))
• Account for risk: keep records available through Minnesota’s four-year medical malpractice window and extend retention under any legal hold. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/cite/541.076?utm_source=openai))
• Preserve securely and lawfully; hospitals may rely on microfilm or electronic imaging as authorized by Section 145.30. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.30))

In short, build your policy on Minnesota’s facility- and profession-specific rules, then overlay HIPAA documentation and any federal program standards so you reliably meet the strictest applicable requirement. ([revisor.mn.gov](https://www.revisor.mn.gov/statutes/2024/cite/145.32))
