PATHOLOGY CODE 



REPRESENTATIVE LIST OF DISEASES 

 AND IDENTIFYING CODE SYMBOLS 



Other pathologies may be added to this list and symbols constructed according to the procedures 

 and policies outlined in the Key discussion of the Pathology Code. 



The spaces between the fourth and fifth and between the sixth and seventh units of the symbols 

 have no significance in the list except to facilitate analysis of the second and third (anatomical and 

 etiological) parts of the symbol. 



The information coded into these symbols assigned to pathologies is, or can be, supplemented 

 by coding in Fields H and T-2, as described in the Key. In a few instances, to describe a pathology 

 adequately, it is necessary to use Field H and, for these pathologies, the definition of each includes 

 specification of that Field H code entry. This is generally the case with infectious diseases entered 

 in the list and with certain others such as dermatomyositis, sprue, arthritis due to rheumatic fever, 

 jaundice, etc. 



The anatomy list of Field H should be consulted for the definitions of the second part of the 

 symbol (Columns 19, 20, and 21); the etiology list (following this list of pathologies) should be con- 

 sulted for the definitions of the third part (Columns 22 and 23). A supplementary list of general 

 pathological manifestations, indicated by letter symbols in Column 2 5, follows the etiology list.
