N.Y. Comp. Codes R. & Regs. tit. 4 § 73.12
The provisions of this Chapter, insofar as they apply to employees in the negotiating units established pursuant to article 14 of the Civil Service Law and their dependents, shall be continued; provided, however, that during periods of time when there is in effect an agreement between the State and an employee organization reached pursuant to the provisions of said article 14, the provisions of such agreement and the provisions of this Chapter shall both be applicable. In the event the provisions of the agreement are different from the provisions of this Chapter, the provisions of the agreement shall be controlling. The president may, upon approval by the Director of the Budget, provide for the extension of the negotiated provisions of such agreement, in whole or in part, to officers and employees not in a negotiating unit within the meaning of article 14 of the Civil Service Law and may extend provisions regarding the modified State cost of premium or subscription charges to such employees or retirees.
