Corrosion of cornea and conjunctival sac, left eye, sequela

This code signifies a permanent or long-term complication affecting the cornea and conjunctival sac of the left eye, resulting from a past chemical burn or corrosive injury. These sequelae can include chronic inflammation, scarring, corneal opacities, or other persistent structural changes that impact vision or eye comfort.

Use this code when documenting a patient presenting with a chronic condition of the left eye that is directly attributable to a previous corrosive injury to the cornea and conjunctival sac. This applies to follow-up encounters for ongoing management of these long-term effects, even if the original acute injury occurred months or years prior.

• Always ensure documentation clearly links the current ocular condition to a past corrosive injury.
• This code is for sequela (S) and should not be used for the initial acute injury or active healing phase.
• Consider additional codes for specific complications, such as corneal scarring (e.g., H17.0-H17.9) or chronic conjunctivitis (e.g., H10.4-H10.5), if applicable and supported by documentation.
