10 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.

Single condition causing multiple impairments

(3) 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).

(4) 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

(5) 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.

(6) Where a common or combined impairment resulting from two or more conditions is assessed in accordance with subsection 10(5), 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.
