What is the purpose of the 'minimum necessary' principle?

• A. Share PHI with all partners
• B. Share only the PHI necessary for the care task
• C. Require patient consent for all data shares
• D. Increase data sharing across departments

Answer: (B)

The idea behind the minimum necessary principle is to protect patient privacy by using or disclosing only the smallest amount of protected health information needed to accomplish a specific task. In practice, that means when a clinician needs PHI to perform a care task, they should access and share only the information required for that task, nothing more. This limits who can see sensitive data and reduces the risk of unnecessary exposure or breaches.

This principle keeps information flowing to care teams where it’s truly needed, but it doesn’t mean no information can ever be shared. There are important exceptions: information can be shared for treatment, as required by law, or when a patient has given explicit consent. The answer reflects the core idea by focusing on sharing only what’s necessary for the care task. Sharing with all partners, requiring consent for every share, or widening data access across departments beyond what’s needed would go against the intent of minimizing exposure.
