Updated Part 599 Regs for OMH Article 31 Clinic Services

November 21, 2022

New York State’s Office of Mental Health (OMH) has updated the Part 599 regulations for OMH Article 31 clinic services, now called Mental Health Outpatient Treatment and Rehabilitative Services (MHOTRS). These changes add multiple flexibilities including an option to provide Peer Support Services to Children, Youth, Adult, and Older Adult, as well as allowances for offsite service provision for all populations served within MHOTRS programs.

The updated regulations are effective as of promulgation on 11/23/22.  Please note: It will take some time for Westlaw to be updated. A PDF version of the updated regulations attached for reference, formatted to indicate changes made. Any language that is underlined is new language added to the regulations; any language with [brackets] or [brackets and crossed out] is language that has been removed from the regulations.
