Application of the International Classification of Diseases to Dentistry and Stomatology
"When any substantial volume of data has to be recorded, a coherent system of classifying and coding the data is essential, particularly where electronic or mechanical means of retrieval or analysis are to be used. The Application of the International Classification of Diseases to Dentistry and Stomatology (ICD-DA) is intended to provide a practical and convenient basis for the classification and coding of data by all those working in the field of oral and dental disorders. It is derived directly from the Tenth Revision of the International Classification of Diseases (ICD-10), and is concerned with all diseases and conditions that occur in, have manifestations in, or are associated with the oral cavity and adjacent structures. For the purposes of ICD-DA, most of the classifications provided by ICD-10
have been subdivided and expanded; however, data from ICD-DA can be reassembled into ICD categories by simple addition. It is strongly recommended that ICD-DA be used with ICD-10 available for reference."
