The new payment system must be implemented for each hospital at the beginning of the hospital's first fiscal year that commences on or after April 1, 2010. The Department of Health and Human Services shall adopt rules to implement this section. Rules adopted pursuant to this section are routine technical rules as defined by Title 5, chapter 375, subchapter 2‑A.   [PL 2009, c. 213, Pt. CC, §4 (NEW).]
