Corrosion of right eyelid and periocular area, sequela

This code signifies the long-term effects or complications resulting from a chemical burn to the right eyelid and the surrounding tissues of the eye. These sequelae can include scarring, altered tissue texture, chronic inflammation, or functional impairment that persists after the initial corrosive injury has healed.

Use this code when documenting a patient presenting with a current condition or symptom that is a direct consequence of a past corrosive injury to their right eyelid and periocular area. This applies even if the original injury occurred months or years prior and the patient is now being treated for the residual effects.

• Always append the 7th character 'S' for sequela, indicating a late effect of the injury.
• Code any current, active conditions or symptoms resulting from the corrosion in addition to this sequela code.
• Ensure documentation clearly links the current condition to a past corrosive injury of the right eyelid and periocular area.
