12  Selecting the applicable Table and assessing impairments

Selection steps

(1) Table selection is to be made by applying the following steps:

(a) identify the loss of function; then

(b) refer to the Table related to the function affected; then

(c) identify the correct impairment rating.

(2) The Table specific to the impairment being rated must always be applied to that impairment unless the instructions in a Table specify otherwise.

(3) When identifying the loss of function, consideration should be given to the ongoing side effects of prescribed medication and treatment when the impairment from, or related to, the side effects is not expected to significantly improve.

Single condition causing multiple impairments

(4) Where a single condition causes multiple impairments, each impairment should be assessed under the relevant Table.

Example: a stroke may affect different functions, thus resulting in multiple impairments which could be assessed under a number of different Tables including: upper and lower limb function (Tables 2 and 3); brain function (Table 7); communication function (Table 8); and visual function (Table 12).

(5) When using more than one Table to assess multiple impairments resulting from a single condition, impairment ratings for the same impairment must not be assigned under more than one Table.

Multiple conditions causing a common impairment

(6) Where two or more conditions cause a common or combined impairment, a single rating should be assigned in relation to that common or combined impairment under a single Table.

(7) Where a common or combined impairment resulting from two or more conditions is assessed in accordance with subsection 12(6), it is inappropriate to assign a separate impairment rating for each condition as this would result in the same impairment being assessed more than once.

Example: the presence of both heart disease and chronic lung disease may each result in breathing difficulties. The overall impact on function requiring physical exertion and stamina would be a combined or common effect. In this case, a single impairment rating should be assigned using Table 1.
