Foreign body in cornea, right eye, sequela

This code indicates a long-term or late effect resulting from a foreign body that was previously lodged in the cornea of the patient's right eye. This could include conditions such as corneal scarring, persistent inflammation, or vision impairment directly attributable to the past foreign body. It signifies that the acute phase of the foreign body presence has resolved, but residual issues remain.

Use this code when documenting a patient presenting with a current ocular condition that is a direct consequence of a foreign body having been in the right corneal tissue at some point in the past. This applies when the foreign body is no longer present, but its impact is still being treated or monitored. Examples include follow-up for corneal opacities or astigmatism caused by a prior corneal foreign body.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., H17.01 for adherent leucoma, right eye).
• Ensure documentation clearly links the current condition to a past foreign body in the right cornea.
• Do not use this code if the foreign body is still present; instead, use an acute foreign body code.
