SUPPLEMENTARY CLASSIFICATION OF EXTERNAL CAUSES OF INJURY AND POISONING (E000-E999)
This section is provided to permit the classification of environmental events, circumstances, and conditions as the cause of injury, poisoning, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used in addition to a code from one of the main chapters of ICD-9-CM, indicating the nature of the condition. Certain other conditions which may be stated to be due to external causes are classified in Chapters 1 to 16 of ICD-9-CM. For these, the "E" code classification should be used as an additional code for more detailed analysis.
Machinery accidents [other than those connected with transport] are classifiable to category E919, in which the fourth digit allows a broad classification of the type of machinery involved.
Categories for "late effects" of accidents and other external causes are to be found at E929, E959, E969, E977, E989, and E999.

Note:
This category is to be used to indicate circumstances classifiable to E960-E968 as the cause of death or disability from late effects, which are themselves classifiable elsewhere. The "late effects" include conditions reported as such, or as sequelae which may occur at any time after the injury purposely inflicted by another person.
