What is the "minimum necessary" standard under HIPAA?

• A. The minimum necessary standard requires using or disclosing only the PHI needed to accomplish the intended purpose.
• B. Use or disclose only the PHI needed to accomplish the intended purpose.
• C. The minimum necessary standard applies only to disclosures to patients.
• D. The minimum necessary standard allows full PHI disclosure to marketing vendors with authorization.

Answer: (B)

Minimum necessary means you only share or use the portion of PHI that is needed to accomplish the specific task. The idea is to limit exposure of information so privacy risks are reduced, by choosing the smallest amount of data required for the purpose. The best way to state this is that you should “use or disclose only the PHI needed to accomplish the intended purpose.” That phrasing directly captures the obligation: the information shared should be limited to what is essential for the task at hand. In practice, this drives practices like role-based access, careful data minimization, and procedures to determine what counts as necessary. There are also common exceptions, such as disclosures to the patient themselves, disclosures made with patient authorization, or disclosures required by law.
