External constriction of nose, initial encounter

This code signifies an injury to the nose caused by an external force that constricts or compresses the nasal structure. This could involve a tight band, ligature, or other object causing pressure and potential damage to the external nose. It represents the initial phase of treatment for such an injury.

Apply this code when documentation clearly indicates an external constricting force as the cause of a nasal injury, and the patient is receiving active treatment for the first time. This code is appropriate for emergency department visits, initial physician consultations, or hospital admissions for this specific injury.

• Ensure documentation specifies "external constriction" and not another type of nasal injury like a contusion or laceration.
• Always append the appropriate seventh character for subsequent encounters (D) or sequela (S) after the initial encounter.
• Consider co-reporting with an external cause code (V00-Y99) to provide more detail about the circumstances of the injury.
