    STEP

Find the relative contribution of each contributing condition.

Suppose that, on medical advice, it is found that the contributions by chronic bronchitis and ischaemic heart disease are in the ratio of 2:1.

Break up the single impairment rating into parts.
      3 As the ratio is 2:1, Table 20.1 or Table 20.4 is to be used.
From either of these it is found that 20 points apportioned in the ratio of 2:1 gives 14 and 7 as the two contributory impairment ratings. Thus the functional impairment rating for chronic bronchitis is 14 points and for ischaemic heart disease it is 7 points.

    STEP

Compare ratings from two tables for each condition.
      4 Compare the ratings for ischaemic heart disease (7 versus
10 from Table 1.6) and for chronic bronchitis (14 versus
5 from Table 1.10). Taking the higher rating in each case, the assessment will be: ischaemic heart disease 10 points, chronic bronchitis 14 points.

    STEP

Do not combine individual ratings until the end.
5 If this veteran had no other accepted conditions, the final combined impairment rating would be 25 points (10 &
                    14 = 23, rounded to 25) instead of 20 points without
apportionment.

The calculations in the above example can be conveniently set out in a worksheet format, as illustrated below.

     For purposes of the above worksheet

"Accepted Conditions"     means   the accepted conditions that con- tribute to a single impairment rating to be apportioned.

"Relative Contribution"   means   the ratio of the relative contribu- tions which the conditions make to the total impairment (in the above example, the ratio is 1:2, written as "1" in the top row of column A, and "2" in the bottom row of column A).

"Functional Rating"       means   the ratings  for the conditions obtained after apportionment.

"Other Impairment"        means   the applicable rating for the con- ditions obtained from an Other Impairment table.

"Rating for Condition"    means   the higher of the ratings in columns B and C of the same row. This is the final impairment rating for the condition named in that row.

For convenience, Tables 20.1 and 20.2 give the apportionment for impairment ratings that are multiples of 5. Table 20.3 to 20.13 give the apportionment for all relevant integral values of impairment ratings for certain given ratios.

    Table 20.1 can be applied to find the two relevant values when any impairment rating has to be apportioned between two conditions in any of the given ratios.

    The top row contains the ratios into which the impairment rating needs
