The External Cause of Injuries index contains codes found in Chapter 19, Injury, poisoning & certain other consequences of external causes , and Chapter 20, External causes of morbidity, of the ICD-10-CM. The codes begin with the letters S and T for Chapter 10, and V, W, X, and Y in Chapter 20.
They can be reported with any condition due to an external cause and are not limited to injuries or poisonings. Use the full range of external cause codes to completely describe the cause, intent, place of occurrence and if applicable, the activity of the patient at the time of the event, and the patient’s status.

The external cause-of-injury codes are the ICD codes used to classify injury events by mechanism and intent of injury. Intent of injury categories include unintentional, homicide/assault, suicide/intentional self-harm, legal intervention or war operations, and undetermined intent.
External cause codes identify the cause of an injury or health condition, the intent (accidental or intentional), the place where the incident occurred, the activity of the patient at the time of the incident, and the patient's status (such as civilian or military).
An external cause code can never be a principal (first-listed) diagnosis. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the classification indicating the nature of the condition.
External cause of injury codes are used to define environmental events, circumstances and conditions such as the cause of injury, poisoning, and other adverse effects related to injury morbidity and mortality.
An external cause is defined in the National Health Data Dictionary Version 8 (NHDC 1999) as the event, circumstance or condition associated with the occurrence of injury, poisoning or violence. Whenever a patient has a principal or additional diagnosis of an injury or poisoning, an external cause should be recorded.
Example 1: An initial encounter (character “A”) describes an episode of care during which the patient is receiving active treatment for the condition. Examples of active treatment are: surgical treatment, emergency department encounter, and evaluation and continuing treatment by the same or a different physician.
External cause codes are used to report injuries, poisonings, and other external causes. (They are also valid for diseases that have an external source and health conditions such as a heart attack that occurred while exercising.)
