You don't explain how the nurse came to leave a message on your Mother's phone, not yours. As a first step, you could speak to the practice administrator or your primary care physician, both of whom likely will take a very dim view of this careless behavior by a nurse employee of the practice. But setting that aside, you MAY have a federal claim for a HIPPA violation and a state claim for breach of privacy. These claims could be against the practice that employed the nurse as well as the involved nurse. Additionally, you could report the involved nurse to the Arizona Board of Nursing, which licenses nurses in Arizona and investigates complaints against them by patients like you. Making a complaint to the Board would be a good step after you speak to your physician. NOTE: THIS INFORMATION IS FOR GENERAL PURPOSES ONLY AND DOES NOT CREATE AN ATTORNEY-CLIENT PRIVILEGE.
