Cicatricial entropion of left upper eyelid

This code describes an inward turning of the left upper eyelid margin due to scar tissue formation. This cicatricial change causes the eyelashes to rub against the cornea, leading to irritation and potential damage.

Apply this code when documentation specifies entropion of the left upper eyelid caused by scarring, often resulting from trauma, inflammation, or previous surgery. The physician's notes should clearly indicate the laterality (left upper eyelid) and the cicatricial etiology.

• Differentiate from spastic or senile entropion, which have different ICD-10-CM codes.
• Ensure the documentation specifies "cicatricial" as the cause; otherwise, an unspecified entropion code may be more appropriate.
• Verify laterality (left upper eyelid) to avoid incorrect coding for the right or unspecified eye.
