(a) The rate to be paid by the state to rehabilitation centers, including but not limited to, centers affiliated with the Easter Seal Society of Connecticut, Inc., for services to patients referred by any state agency, except employment opportunities and day services, shall be determined annually by the Commissioner of Social Services who shall prescribe uniform forms on which such rehabilitation centers shall report their costs, except that rates effective April 30, 1989, shall remain in effect through May 31, 1990, and rates in effect February 1, 1991, shall remain in effect through December 31, 1992, except those which would be decreased effective January 1, 1992, shall be decreased. For the rate years beginning January 1, 1993, through December 31, 1995, any rate increase shall not exceed the most recent annual increase in the consumer price index for urban consumers. Such rates shall be determined on the basis of a reasonable payment for necessary services rendered. Nothing contained herein shall authorize a payment by the state to any such rehabilitation center in excess of the charges made by such center for comparable services to the general public. The Commissioner of Social Services shall establish a fee schedule for rehabilitation services to be effective on and after January 1, 1996. The fee schedule may be adjusted annually beginning July 1, 1997, to reflect necessary increases in the cost of services.
