Late effects of injury, undetermined whether accidentally or purposely inflicted

This code signifies a health condition or sequela that is a direct consequence of a past injury, where the original intent of the injury (accidental vs. intentional self-harm or assault) cannot be determined from the medical record. It is used when the long-term effects, rather than the acute injury, are being treated.

Apply this code when a patient presents with a chronic or residual condition clearly linked to a prior injury, but the documentation lacks sufficient detail to classify the original injury's intent. Examples include chronic pain, scar contractures, or neurological deficits stemming from an old injury where the mechanism of injury is unknown or ambiguously documented.

• Always sequence this code after the code for the specific late effect being treated (e.g., chronic pain, paralysis).
• Avoid using this code if the original injury's intent (accidental, self-inflicted, assault) is clearly documented; instead, use the appropriate late effects code from E929, E959, or E969.
• Query the provider for clarification if the intent of the original injury is unclear, as more specific coding may be possible.
