In McGee Guest Home, Inc. v. Dep't of Soc. & Health Servs., 142 Wn.2d 316, 12 P.3d 144 (2000), the Court addressed the question of whether the Department of Social and Health Services (DSHS) invalidly established a "rule" by adopting a two tiered reimbursement scheme for congregate care facilities (CCF), which care for mentally ill wards of the State. McGee, 142 Wn.2d at 321. The regulation guiding DSHS in how it should reimburse CCFs was broad, stating only that the rates would be established by the Department. The sole statutory requirement was that the rates be "reasonable." RCW 74.08.045; see also McGee, 142 Wn.2d at 327.
