N.Y. Comp. Codes R. & Regs. tit. 14, § 680.5
(d) Individuals admitted to a specialty hospital shall require simultaneous assessment or treatment for their health care needs and structured programming for their developmental disabilities. A specialty hospital covered under this regulation shall admit only individuals who have had a comprehensive assessment (see section 680.13) within the 90 days prior to admission. This assessment shall have identified both the individual's developmental disability (ies) and health care needs which will require more than three hours of daily individualized attention from health care staff. In addition, there shall be an identification of the specific service(s) required by the individual in terms of type and frequency and a declaration of the service outcomes to be achieved which are congruent with the conditions necessitating admission. A current individual program plan developed by a State developmental center for the individual within the 90 days prior to admission is considered as complying with this requirement. However, prior admission to a developmental center shall not be a requirement for eligibility for a specialty hospital.
(i) At the time of admission, the type of placement and proposed location (if known) shall be identified and documented in the individual's record for preparation for each individual's placement subsequent to leaving the specialty hospital.
