Person injured in collision betw car and hv veh, sequela

This code signifies a long-term health condition or complication resulting from a past traffic accident involving a car and a heavy transport vehicle. It indicates that the patient is presenting for treatment of a residual effect directly attributable to that specific type of collision, rather than the acute injury itself.

Apply this code when documenting conditions such as chronic pain, neurological deficits, scarring, or psychological sequelae (e.g., PTSD) that are a direct consequence of a car-heavy transport vehicle collision that occurred in the past. This code is appropriate for follow-up visits addressing these lasting impacts.

• Always use 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 car-heavy transport vehicle accident.
• Verify that the encounter is for a sequela and not an acute injury from a recent accident, which would require an acute injury code.
