Corrosion of cornea and conjunctival sac, unsp eye, sequela

This code signifies a long-term complication or residual effect resulting from a chemical burn or corrosive injury to both the cornea and the conjunctival sac. It indicates that the specific eye affected is not documented, and the acute phase of the injury has passed.

Apply this code when documenting a patient presenting with a chronic condition, such as scarring, corneal opacities, or persistent irritation, that is directly attributable to a past corrosive injury of the eye. This is appropriate for follow-up visits addressing these lasting effects, not the initial acute injury.

• Ensure the medical record clearly states the condition is a sequela of a corrosive injury, not an acute event.
• Only use this code when the affected eye (left or right) is not specified in the documentation.
• Always look for more specific codes if the laterality of the eye is known (e.g., T26.61XS for right eye, T26.62XS for left eye).
