Q. We decided to improve physical security by distributing visitor badges to visitors and patients. A color-coded badge indicates the wearer's destination by floor. The facility's mental health clinic is the only treatment center on the floor where it is located. Some mental health patients visit our cafeteria, which is open to work force members, visitors, and other patients, before their appointments. Does the possibility that an individual might know the color associated with the location of the mental health clinic constitute a HIPAA violation?
