Corrosion of cornea and conjunctival sac, right eye, sequela

This code signifies the long-term effects or complications arising from a chemical burn to the cornea and conjunctival sac of the right eye. These sequelae can include chronic inflammation, scarring, vision impairment, or other persistent issues resulting from the initial corrosive injury.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past chemical burn to their right eye. This is appropriate for follow-up visits addressing the chronic impact of the injury, rather than the acute phase.

• Always assign this code as a secondary diagnosis, following the code for the specific sequela (e.g., corneal scar, chronic conjunctivitis).
• Ensure documentation clearly links the current condition to a previous corrosive injury of the right eye.
• The "S" in the 7th character indicates sequela, meaning the initial injury has healed, but its lasting effects are being treated.
