Three categories of permitted uses and disclosures of PHI that do not require patient authorization under the Privacy Rule.
Treatment, Payment, and Health Care Operations (TPO) are the three fundamental categories under which covered entities may use and disclose protected health information without obtaining written authorization from the individual. This framework is central to how HIPAA balances patient privacy with the practical needs of the healthcare system. TPO enables the essential functions of healthcare delivery, billing, and organizational management to proceed without requiring individual consent for each transaction, while still requiring that all other uses and disclosures either have authorization or fall under a specific permitted exception.
Treatment encompasses the provision, coordination, or management of healthcare and related services, including consultations between providers and referrals. A doctor sharing patient information with a specialist for a consultation is a treatment use. Payment includes activities related to obtaining payment for healthcare services, such as billing, claims management, utilization review, and determining eligibility and coverage. An example is sending patient information to an insurer for claims processing. Health Care Operations include a wide range of administrative, quality assurance, and business management activities, including quality assessment and improvement, conducting audits, case management, business planning, resolution of internal grievances, and professional competence review. These operations are necessary for running a healthcare organization but do not involve direct patient care or billing.
An important nuance of TPO is how the Minimum Necessary Standard applies differently across the three categories. For treatment purposes, the Minimum Necessary Standard does not apply, recognizing that healthcare providers need complete information to deliver safe and effective care. However, for payment and health care operations, the Minimum Necessary Standard does apply, meaning organizations must make reasonable efforts to limit the PHI used or disclosed to the minimum amount necessary to accomplish the intended purpose. This distinction is important for organizational policies and access controls, and organizations must train their workforce to understand when the Minimum Necessary Standard applies and how to implement it in practice.
