Crashing of motor vehicle, undetermined intent, sequela

This diagnosis code signifies long-term complications or conditions arising from a motor vehicle crash where the intent (accidental, self-harm, or assault) could not be determined. It is used to indicate that the patient is experiencing residual effects directly attributable to such an event that occurred in the past. These sequelae can manifest as chronic pain, neurological deficits, psychological trauma, or permanent physical impairments.

This code is appropriate for encounters where a patient is being treated for a current condition that is a direct consequence of a past motor vehicle crash of undetermined intent. It should be used after the acute phase of injury has passed, and the patient is presenting for ongoing management of chronic issues. Examples include follow-up for persistent spinal cord injury, traumatic brain injury, or chronic pain syndrome stemming from the original incident.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to the past motor vehicle crash and explicitly states "undetermined intent."
• Do not use this code for initial or acute injury encounters; it is strictly for sequelae.
