What is the principle of the minimum necessary in PHI handling?

• A. Releasing PHI to any entity with a signed release
• B. Releasing PHI to any staff member upon request
• C. Limiting access and disclosure to the minimum amount required to accomplish the task
• D. Never disclosing PHI under any circumstance

Answer: (C)

Minimum necessary means you should only access, use, and disclose the smallest amount of PHI needed to accomplish the task. This keeps patient information private and reduces unnecessary exposure.

In practice, this involves limiting access to PHI to those who need it for their role and sharing only the specific data required for the purpose. For example, someone processing a claim might need the patient name, dates of service, and billing codes, but not the full medical history unless it’s truly needed for the task at hand. Even when a patient authorization or release is involved, you still apply the minimum necessary standard—disclose only what’s needed to fulfill that purpose, not more.

Releasing PHI simply because there’s a signed release, or granting access just because someone requests it, isn’t consistent with this principle. And there are legitimate situations where PHI can be disclosed (treatment, payment, healthcare operations, or as required by law), but even then the disclosure should be limited to what is necessary.
