How does the department determine the severity of multiple impairments?
(1) If you have more than one impairment, we decide the overall severity rating by determining if your impairments have a combined effect on your ability to be gainfully employed.
(2) When you have two or more diagnosed impairments that limit work activities, we assign an overall severity rating as follows:
(i) All impairments are mild and there is no cumulative effect on basic work activities.
(ii) All impairments are mild and there is a significant cumulative effect on one or more basic work activities.
(iii) Two or more impairments are of moderate severity and there is a very significant cumulative effect on basic work activities.
(iv) Two are more impairments are of marked severity.
