Ped on foot injured in collision w hv veh, unsp, sequela

This code describes the long-term effects or complications arising from an injury sustained by a pedestrian who was struck by a heavy transport vehicle or bus. It indicates that the original accident's circumstances (traffic vs. non-traffic) are not specified. This code is used when the initial injury has healed, but the patient continues to experience residual problems directly attributable to the collision.

Apply this code when documenting follow-up care for conditions like chronic pain, limited mobility, neurological deficits, or psychological sequelae that are a direct result of being hit by a heavy vehicle or bus as a pedestrian. This is appropriate for encounters occurring long after the initial injury, once the acute phase of treatment has concluded.

• Always use this code as a secondary diagnosis, following the code for the specific sequela being treated (e.g., chronic pain, scar contracture).
• Ensure the "S" seventh character is appended for sequela, indicating the long-term nature of the condition.
• Avoid using this code for initial injury encounters or for active treatment of acute injuries.
