Final answer:
The use or disclosure of PHI without patient authorization may be required for public health and safety reasons or in certain legal situations. Healthcare providers may also disclose PHI without authorization for treatment, payment, or healthcare operations.
Step-by-step explanation:
The use or disclosure of PHI (Protected Health Information) without patient authorization is required in certain situations for the purpose of public health or safety. One example is when healthcare professionals are required by law to report certain diseases or conditions to public health authorities. This ensures that appropriate measures can be taken to prevent the spread of communicable diseases or protect individuals from harm. Another example is when there is a court order or subpoena requiring the disclosure of PHI.
Furthermore, healthcare providers may also disclose PHI without patient authorization when it is necessary for treatment, payment, or healthcare operations. For example, a healthcare provider may share relevant patient information with other healthcare professionals involved in the patient's care to ensure coordinated and quality treatment.
