E959 Late effects of self-inflicted injury
E969 Late effects of injury purposely inflicted by another person
E977 Late effects of injuries due to legal intervention
E989 Late effects of injury, undetermined whether accidentally or purposely inflicted

Late effect E codes are found in the Index to External Causes under ‘Late effect of.”
Guidelines for E Codes
E codes may be used as additional codes with any code in the categories 001 – V84 to indicate the injury, poisoning, or adverse effect due to external cause.
Assign the appropriate E code for all initial treatments of an injury, poisoning, or adverse effect of drugs.
Use a late effect E code for subsequent visits when a late effect of the initial injury or poisoning is being treated.
Use the full range of E codes to completely describe the cause, intent, and place of occurrence for all injuries, poisonings, and adverse effects of drugs.
Guidelines for E Codes (continued)
Assign as many E code as necessary to fully explain each external cause.
If only one E code can be recorded, assign the one most related to the principal diagnosis.
Select the appropriate E code by referring to the Alphabetic Index to External Causes and the Tabular List’s inclusion and exclusion notes.
E Codes for Child and Adult Abuse
When the cause of an injury is intentional child or adult abuse (995.50 – 995.59, 995.80 – 995.85), the first-listed E code should be assigned from categories E960 – E968, Homicide or injury purposely inflicted by other persons.
An additional E code should be used to identify the perpetrator of the abuse.
