Provides that the rates for the listed services shall be increased, beginning on January 1, 2025 and each January 1 thereafter, based on the annual increase in the national hospital market basket price proxies (DRI) hospital cost index from the midpoint of the calendar year 2 years prior to the current year, to the midpoint of the preceding calendar year. Provides that in no instance shall the adjustment result in a reduction to the rates in place at the time of the required adjustment.
