The HIPAA Privacy Rule requires a covered entity to make reasonable efforts to limit use, disclosure of, and requests for protected health information to the minimum necessary to accomplish the intended purpose. To allow covered entities the flexibility to address their unique circumstances, the Rule requires covered entities to make their own assessment of what protected health information is reasonably necessary for a particular purpose, given the characteristics of their business and workforce, and to implement policies and procedures accordingly. This is not an absolute standard and covered entities need not limit information uses or disclosures to those that are absolutely needed to serve the purpose. Rather, this is a reasonableness standard that calls for an approach consistent with the best practices and guidelines already used by many providers and plans today to limit the unnecessary sharing of medical information.
The minimum necessary standard requires covered entities to evaluate their practices and enhance protections as needed to limit unnecessary or inappropriate access to protected health information. It is intended to reflect and be consistent with, not override, professional judgment and standards. Therefore, it is expected that covered entities will utilize the input of prudent professionals involved in health care activities when developing policies and procedures that appropriately limit access to personal health information without sacrificing the quality of health care.
