N.Y. Comp. Codes R. & Regs. tit. 14, § 85.1
(c) The Mental Hygiene Law requires the certification of any nonresidential or outpatient facility operated by a corporation or a public agency to provide examination, diagnosis, care, treatment, rehabilitation or training to people with a disturbance in behavior, feeling, thinking or judgment so severe as to require care and treatment to people with subaverage intellectual functioning which originates during the developmental period and is associated with impairment in adaptive behavior, or to people who habitually use alcoholic beverages to the extent that this is beyond their control or endangers health, safety or welfare. A number of terms are in common usage to refer to such facilities, among them being psychiatric clinic, mental health clinic, child guidance clinic, day hospital, day training center and alcoholism clinic. In an effort to make more comfortable their utilization by the mentally handicapped, some outpatient facilities have made use of less distinctive titles.
