PART 4_SCHEDULE FOR RATING DISABILITIES--Table of Contents
 
                   Subpart A_General Policy in Rating
 
Sec. 4.22  Rating of disabilities aggravated by active service.

    In cases involving aggravation by active service, the rating will 
reflect only the degree of disability over and above the degree existing 
at the time of entrance into the active service, whether the particular 
condition was noted at the time of entrance into the active service, or 
it is determined upon the evidence of record to have existed at that 
time. It is necessary therefore, in all cases of this character to 
deduct from the present degree of disability the degree, if 
ascertainable, of the disability existing at the time of entrance into 
active service, in terms of the rating schedule, except that if the 
disability is total (100 percent) no deduction will be made. The 
resulting difference will be recorded on the rating sheet. If the degree 
of disability at the time of entrance into the service is not 
ascertainable in terms of the schedule, no deduction will be made.
