Apply HIPAA to the following scenario:

Dr. Doe, a psychiatrist, is having dinner out with colleagues when she is paged by her answering service with an urgent message to call one of her patients. She left her cell phone at home, so she borrows the phone of one of her dinner companions to return the patient's call. The borrowed cell phone automatically maintains a log of the outgoing phone number. Can a patient whose identity is thereby revealed file a complaint against Dr. Doe?
