How long must treatment records be retained?

• A. 5 years
• B. 10 years
• C. 7 years
• D. 12 years

Answer: (C)

The key idea is how long treatment records must be kept. In Wisconsin, the minimum retention period for treatment records is seven years from the date of last service. This duration supports regulatory and potential liability needs, and it also helps ensure continuity of care if the client returns or if records are needed for audits or investigations. If the client was a minor, the records should be kept until seven years after they reach the age of 18, whichever is longer. Longer retention isn’t typically required for general practice, so seven years is the standard answer.
