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

This code signifies a long-term or residual effect resulting from a foreign body having been present on the external surface of the left eye, where the specific part of the eye affected is not documented. This could include chronic irritation, scarring, or vision impairment that persists after the foreign body has been removed or is no longer acutely present.

Use this code when documenting a patient presenting with a current condition directly attributable to a past foreign body on the left external eye. This is appropriate for follow-up visits addressing ongoing complications such as corneal scarring, chronic conjunctivitis, or persistent discomfort that developed as a consequence of the initial foreign body.

• The "S" in the 7th character indicates a sequela, meaning the current condition is a residual effect of a past injury.
• Ensure documentation clearly links the current symptoms or condition to a previous foreign body on the left external eye.
• Avoid using this code for acute foreign body encounters; instead, use the appropriate acute foreign body code.
