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

General Retention Periods for Medical Records

Wisconsin sets baseline retention rules by provider type. For physicians, the Wisconsin Medical Examining Board requires you to keep patient health care records at least five years after the date of the last entry. Dentists must keep patient dental records at least ten years after the last entry. These timeframes are minimums—your internal medical record retention schedule may be longer based on risk, payer contracts, or accreditation. ([dsps.wi.gov](https://dsps.wi.gov/Documents/RulesStatutes/Med21EIA.pdf))

Hospitals must retain medical records for a minimum of five years, though each hospital’s policy can set a longer period to meet historical, legal, teaching, or patient-care needs. Home health agencies and nursing homes have their own five‑year baselines (detailed below). Across all settings, HIPAA compliance requires you to safeguard Patient Health Information (PHI) for as long as you maintain it, and to keep HIPAA administrative documentation (for example, privacy policies and Notices of Privacy Practices) for six years—this HIPAA rule does not set how long to keep patient charts.

Retention Requirements for Mental Health and Substance Abuse Records

Wisconsin’s confidentiality rules for mental health treatment records require you to retain records for at least seven years after treatment is completed. For minors, you must keep records until the individual turns 19 or seven years after treatment ends, whichever is longer. ([regulations.justia.com](https://regulations.justia.com/states/wisconsin/dhs/dhs-30-100/chapter-dhs-92/section-dhs-92-12/))

Certified substance use disorder programs (DHS 75) have specific “certified program record retention” rules: services must retain all records required under Chapter DHS 75 for seven years, and client records must also comply with DHS 92 and, where applicable, 42 CFR Part 2. Build your Healthcare Provider Recordkeeping policies to reflect these certified program obligations. ([regulations.justia.com](https://regulations.justia.com/states/wisconsin/dhs/dhs-30-100/chapter-dhs-75/subchapter-ii/section-dhs-75-11/))

Retention Guidelines for Minor Patient Records

For mental health and substance use services, special rules apply to minors: retain records until the patient turns 19 or seven years after treatment completion, whichever is longer. Outside those areas (for example, general physician or hospital care), Wisconsin does not add a longer statutory period solely because the patient was a minor—so the provider‑specific minimums (often five years) apply unless a payer or federal program requires more. ([regulations.justia.com](https://regulations.justia.com/states/wisconsin/dhs/dhs-30-100/chapter-dhs-92/section-dhs-92-12/))

Record Retention for Medicaid and Medicare Providers

Wisconsin Medicaid (ForwardHealth) requires you to keep documentation—both medical and financial—for at least five years from the date of payment; Rural Health Clinics must retain records for at least six years. Ending participation does not end your duty to produce or protect records. Align your ForwardHealth documentation policies to these timelines. ([regulations.justia.com](https://regulations.justia.com/states/wisconsin/dhs/dhs-101-109/chapter-dhs-106/section-dhs-106-02/))

Medicare imposes additional federal timelines. Under 42 CFR 424.516(f), providers and suppliers that furnish, order, certify, refer, or prescribe Medicare Part A or B services must maintain supporting medical records for seven years from the date of service. Hospitals participating in Medicare also must meet the hospital Conditions of Participation, which require clinical records to be retained at least five years. If you bill Medicare, set your schedule to satisfy the longest applicable rule. ([cms.gov](https://www.cms.gov/files/document/mln4840534-medical-record-maintenance-and-access-requirements.pdf))

Retention Policies for Nursing Homes

Licensed nursing homes must keep each resident’s original medical record (and any authorizing court documents) for at least five years after discharge or death. Facilities must also plan for storage, safekeeping, and continuity of records if ownership changes or the facility closes. ([wirules.elaws.us](https://wirules.elaws.us/rule/DHS132.45%284%29%28c%29))

Retention Standards for Home Health Agencies

Home health agencies must maintain a medical record for each patient and retain it for a minimum of five years following discharge. When transferring a patient, the agency must provide the receiving organization a copy or summary of the record. These state requirements align with the federal HHA Condition of Participation on five‑year clinical record retention. ([regulations.justia.com](https://regulations.justia.com/states/wisconsin/dhs/dhs-110-199/chapter-dhs-133/section-dhs-133-21/?utm_source=openai))

Medical Record Retention for Hospitals

Wisconsin hospitals must have written preservation policies and keep medical records at least five years; many elect to go longer for legal or operational reasons. Hospitals that participate in Medicare must also satisfy the federal Condition of Participation requiring at least five‑year retention of clinical records. Coordinate your Medical Record Retention Schedule to meet both Wisconsin Department of Health Services rules and any federal payer obligations. ([wirules.elaws.us](https://wirules.elaws.us/rule/DHS124.14))

Conclusion

In Wisconsin, start with the provider‑specific minimums (often five years, longer in dentistry, mental health, and certified substance use programs), then layer in payer rules: ForwardHealth’s five years from payment (six for RHCs) and Medicare’s seven‑year documentation rule. Build HIPAA‑sound processes that protect PHI for as long as you keep it, and publish a clear, organization‑wide retention schedule so staff know exactly what to save—and for how long.
