Does a patient need to provide written authorization to release phi to another physican?

Yes, a patient generally needs to provide written authorization to release their Protected Health Information (PHI) to another physician, as mandated by the Health Insurance Portability and Accountability Act (HIPAA). This authorization ensures that the patient is aware of and consents to the sharing of their medical information. However, there are exceptions where PHI can be shared without authorization for treatment purposes or in certain emergency situations.
