How is it determined which impairment rating system is to be used to rate specified and unspecified disabilities?
(1) Specified disabilities are rated in one of two ways:
(a) Impairment due to amputation, total loss of hearing, and total loss of vision are rated according to RCW 51.32.080
(b) Impairment for the loss of function of extremities, as well as partial loss of hearing or vision, is rated using a nationally recognized impairment rating guide unless otherwise precluded by department rule.
