2: Determine the relative contribution of the accepted and non-accepted conditions.

The judgement of the relative contributions should be based on proper medical advice.

The contribution should be expressed in the form:

'The accepted condition contributes "not at all", "about one quarter", "about one third", "about half", etc'.

If more than one accepted condition contributes to the relevant impairment rating, the contribution of the accepted conditions is to be treated as a single entity.

If more than one non-accepted condition contributes to the relevant impairment rating, the contribution of the non-accepted conditions may be treated as a single entity.

Step 3: Determine the impairment rating attributable solely to the accepted condition by applying Table 19.2 or Table 19.1.

Substep 3A  In the columns of Table 19.2 headed "Impairment Rating" find the impairment rating to which partially contributing impairment is being applied. The row extending to the right of the column in which this figure is written is "The Row" for purposes of substep 3C.
Substep 3B  Take the relative contribution to the impairment by the accepted condition, determined in Step 2. In the top row of Table 19.2 find the description of that contribution.

            (If the impairment rating  used in substep 3A was between 1 and 45 inclusive, the required description of the contribution is to be found in columns 2–8 of Table 19.2. If the impairment rating  used in substep 3A was between 46 and 90 inclusive, the required description of the contribution is to be found in columns 10–16 of Table 19.2.)

            The column in which this description is written is "The Column" for purposes of substep 3C.
Substep 3C  Find the intersection of The Row and The Column. The number written on the intersection is the impairment rating for the accepted condition.
