Anonymous Complaints

A complaint can be filed anonymously; however, the Board has a difficult time investigating these complaints. If the Board is unable to obtain documentation or evidence of the complaint allegations, the complaint may not be able to be pursued and the complainant will not receive updates regarding the complaint. However, if medical records are required, the patient’s name will have to be disclosed to the physician in order to release the records to the Board.

If you have a complaint about a medical doctor (M.D.), contact the Medical Board of California's Central Complaint Unit at (1-800-633-2322) or (916) 263-2424 or online at

One of the most important ways the Osteopathic Medical Board protects consumers is by investigating consumer complaints. The board reviews complaints against osteopathic physicians and surgeons in a variety of areas.
