Fall/lying/running bef/into moving obj, undet intent, subs

This code describes an injury sustained when an individual falls, lies, or runs into a moving object, or a moving object impacts them, where the intent of the incident cannot be determined. This specific code is for encounters following the initial treatment of the injury.

Apply this code for follow-up visits, rehabilitation sessions, or subsequent evaluations related to an injury from an undetermined intent incident involving a moving object. Examples include a patient returning for physical therapy after being struck by an unknown moving vehicle, or a follow-up for a fracture sustained after falling into an object with unclear intent.

• Ensure the encounter is not the initial treatment for the injury; otherwise, an A or D seventh character is more appropriate.
• Confirm that the intent of the incident (accidental, intentional self-harm, assault) remains undetermined in the clinical documentation.
• Always code the specific injury first, followed by this external cause code.
