Cal. Health and Safety Code § 1254.5

(a) The Legislature finds and declares that the disease of eating disorders is not simply medical or psychiatric, but involves biological, sociological, psychological, family, medical, and spiritual components. In addition, the Legislature finds and declares that the treatment of eating disorders is multifaceted, and like the treatment of chemical dependency, does not fall neatly into either the traditional medical or psychiatric milieu. (b) The inpatient treatment of eating disorders shall be provided only in state licensed hospitals, which may be general acute care hospitals as defined in subdivision (a) of Section 1250, acute psychiatric hospitals as defined in subdivision (b) of Section 1250, or any other licensed health facility designated by the State Department of Public Health. (c) “Eating disorders,” for the purposes of this section, shall have the meaning of the term as defined in the Diagnostic and Statistical Manual of Mental Disorders, as published by the American Psychiatric Association.
