Annual Workmens Compensation earnings limit

I am being told that in the state of Nevada, there is an annual earnings limit, so that once an employee hits that limit, you do not incur any addiitional workmens comp cost for that employee.  Has anyone had to deal with this kind of situation in Payroll and, if so, how did you deal with it?  Right now I am not seeing anything in the workmens comp setup that would let me input an annual limit (there is an executive weekly maximum I see, but not anything else).
