Foreign body on external eye, part unsp, right eye, sequela

This code signifies a past injury to the right eye caused by an unspecified foreign object on its external surface, with the patient now experiencing a residual condition or complication directly attributable to that original foreign body. The initial injury has resolved, but its lasting effects are still present.

Use this code when documenting a patient presenting with a chronic or late-onset symptom, disease, or complication that is a direct consequence of a previously removed or resolved foreign body on the external surface of their right eye. Examples include chronic irritation, scarring, or vision impairment resulting from such an event.

• Ensure the medical record clearly links the current sequela to a past foreign body injury of the right external eye.
• Always use this code with an additional code(s) identifying the specific nature of the sequela (e.g., chronic conjunctivitis, corneal scar).
• The "S" in the 7th character indicates sequela; do not use this code for the initial encounter or subsequent active treatment of the foreign body itself.
