<P> The Eighth Revision Conference convened by WHO met in Geneva , from 6 to 12 July 1965 . This revision was more radical than the Seventh but left unchanged the basic structure of the Classification and the general philosophy of classifying diseases , whenever possible , according to their etiology rather than a particular manifestation . During the years that the Seventh and Eighth Revisions of the ICD were in force , the use of the ICD for indexing hospital medical records increased rapidly and some countries prepared national adaptations which provided the additional detail needed for this application of the ICD . In the USA , a group of consultants was asked to study the 8th revision of ICD ( ICD - 8a ) for its applicability to various users in the United States . This group recommended that further detail be provided for coding hospital and morbidity data . The American Hospital Association 's `` Advisory Committee to the Central Office on ICDA '' developed the needed adaptation proposals , resulting in the publication of the International Classification of Diseases , Adapted ( ICDA ) . In 1968 , the United States Public Health Service published the International Classification of Diseases , Adapted , 8th Revision for use in the United States ( ICDA - 8a ) . Beginning in 1968 , ICDA - 8a served as the basis for coding diagnostic data for both official morbidity ( and mortality ) statistics in the United States . </P>
