List of General Pathological States 



which may be Associated with any 



Anatomical Structure Affected Pathologically 



(Columns 24 and 25) 



These conditions are general states, each of which may be associated with many specifically 

 recognized and named pathologies. They can be used as the final part of pathology symbols in Field E 

 (Columns 24 and 25), serving to distinguish certain pathologies not otherwise adequately described or 

 distinguished by the anatomical and etiological coding in Columns 19-23. 



It is planned to use only a single IBM zone punch in Column 25 to distinguish this category of 

 entries having fixed definitions from the other category coded in Columns 24 and 25, with numerical 

 entries in Column 2 5 and without fixed definitions. (Refer to Division 6 of the discussion of the 

 Pathology Code in the Key. ) Thus, only the letter symbols A through I are used in Column 25 combined 

 with numerical symbols in Column 24 (OA-OI, lA-lI, 2A-2I, etc. ). This will permit 90 such general 

 states which is predicted to be adequate for distinguishing all pathological states for which the CBCC 

 will need symbols.
