Effective June 27, 2010, all California doctors are required to notify their patients that they are licensed by the Medical Board of California and provide the Medical Board’s contact information. This notice may either be prominently posted in the doctor’s office, or it may be in the form of a written statement that is given to the patient.  The written notification must include the Medical Board of California’s telephone number and Web site. Consumers can contact the Medical Board to check on a doctor’s license status or to file a complaint.
