the value obtained by performing Step 6 and combine that with the highest (or equal highest) of the remaining values. Continue until all ratings have been combined into a single value. This figure is the "Combined Impairment Rating".
STEP 8  The individual impairment ratings for the various conditions being assessed are not to be rounded before they are combined using the chart in Table 18.1.
        If the combined impairment rating is not a multiple of five, it should be rounded to the nearest multiple of five. (For purposes of the preceding sentence, "0" is a multiple of five.) Figures ending on "3" or "4" or "8" or "9" should be rounded up, figures ending on "1" or "2" or "6" or "7" should be rounded down. (This also applies when the only impairment rating a veteran obtains = 2. In that case the combined impairment rating = 0.)

Example
To combine 35 and 20, read down the extreme left hand side column of the chart in Table 18.1 until you come to the larger value, 35. In the very bottom row of the chart read from left to right until you come to 20. At the intersection of the row on which 35 is written, and the column above 20, is the number 48.

Therefore, 35 combined with 20 is 48. Due to the construction of this chart, the larger impairment value must be identified at the side of the chart.

Applying the formula to this example gives:

PARTIALLY CONTRIBUTING IMPAIRMENT

INTRODUCTION

Partially contributing impairment is to be applied whenever an impairment is not due solely to the effects of accepted conditions.

How to apply partially contributing impairment

Follow the steps below to apply partially contributing impairment.

(Each step is elaborated in the following pages.)

STEP 1  Determine whether partially contributing impairment applies.                                     Page 193
STEP 2  Determine the relative contribution of the accepted and non-accepted conditions.                 Page 193
STEP 3  Determine the impairment attributable solely to the accepted condition, by applying Table 19.1.  Page 194

Step 1: Determine whether partially contributing impairment applies.

Use relevant medical evidence to determine if any non-accepted conditions contribute to the impairment being assessed.

Step 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
