How can a patient restrict disclosures of their PHI?

A patient can restrict disclosures of their Protected Health Information (PHI) by requesting those restrictions in writing from their healthcare provider. This written request is crucial because it provides a clear, documented basis for the restriction that both the provider and the patient can reference. The written format also allows the healthcare provider to review the request carefully and ensure that it complies with HIPAA regulations while considering the implications of the requested restrictions on patient care.

In practice, while a verbal notification might initiate a discussion about restrictions, it lacks the formal documentation necessary for compliance and enforcement. Additionally, posting a notice on a medical record does not constitute a formal request and is unlikely to be taken seriously or respected by healthcare staff. Finally, refusing to provide PHI is not a viable method for restricting disclosures; it could impede necessary care and treatment without effectively safeguarding information. Thus, the written request is the most official means to manage and control the sharing of a patient's PHI.
