(Apportionment) may also have to be applied to allow for the effect of other accepted conditions or non-accepted conditions respectively.

Step 3: Determine the total combined impairment rating for the various body system impairments attributable to the intermittent condition.

Combine the attributable impairment ratings obtained in Step 2 by applying Table 18.1 (Combined Values Chart) in Chapter 18.

The combined value so obtained is for use only in Step 9.

Step 4: Determine whether the attacks are of one or more significant types and group them accordingly.

If attacks vary in severity, duration or frequency, an average for each parameter is to be established except when the attacks fall naturally and very clearly into groups. In such cases separate the attacks into one or other of these groups. Determine the average severity, duration and frequency of the attacks in each group.

Perform the following four steps separately for each identified group of attacks.

Step 5: Determine the rating level for intermittent attack severity using Table 15.1.
