The HIPAA requirement that covered entities and business associates use, disclose, and request only the minimum amount of PHI necessary to accomplish the intended purpose.
The Minimum Necessary Standard is a fundamental principle of HIPAA that requires covered entities and business associates to make reasonable efforts to limit the use, disclosure, and request of protected health information to the minimum amount necessary to accomplish the intended purpose. This principle reflects HIPAA's core philosophy that PHI should be protected from unnecessary exposure. Rather than sharing entire patient records when only specific information is needed, organizations must develop policies and procedures that identify who needs access to what information and limit access accordingly.
The Minimum Necessary Standard does not apply in all situations. Notably, it does not apply to disclosures to or requests by a health care provider for treatment purposes, recognizing that providers need complete information to deliver safe and effective care. Other exceptions include disclosures to the individual who is the subject of the information, uses or disclosures made pursuant to an individual's authorization, disclosures made to HHS for compliance investigations, uses or disclosures required by law, and uses or disclosures required for compliance with the HIPAA Transaction Rule. For all other purposes, including payment, health care operations, and disclosures to business associates, the Minimum Necessary Standard applies.
Implementing the Minimum Necessary Standard requires organizations to take concrete steps. For internal uses, organizations must identify the workforce members or classes of employees who need access to PHI to perform their duties and limit their access to the categories of PHI required for their job functions. For routine disclosures, organizations should establish standard protocols that limit the information disclosed. For non-routine disclosures, organizations must develop criteria for reviewing requests on a case-by-case basis. Role-based access controls in electronic systems are a primary tool for implementing this standard, ensuring that each user can access only the PHI needed for their specific role.
