Cicatricial lagophthalmos, bi, upper and lower eyelids

This code signifies a condition where scar tissue causes an inability to fully close the eyelids, affecting both the upper and lower eyelids on both eyes. This cicatricial (scar-related) retraction of the eyelids leads to exposure of the ocular surface.

Use this code when documentation clearly indicates lagophthalmos resulting from scar tissue formation, affecting all four eyelids (bilateral upper and lower). This typically follows trauma, burns, chronic inflammation, or surgical complications.

• Ensure documentation specifies "cicatricial" as the etiology, not paralytic or nocturnal lagophthalmos.
• Verify that both upper and lower eyelids, as well as both eyes, are affected to use this specific code.
• Consider sequencing this code with an external cause code if the scarring is due to an injury.
