Cicatricial entropion of right upper eyelid

This code describes an inward turning of the right upper eyelid margin due to scar tissue formation. This cicatricial change causes the eyelashes to rub against the cornea, potentially leading to irritation, corneal abrasion, or ulceration. It is a chronic condition resulting from previous trauma, inflammation, or surgery.

Use this code when documentation explicitly states "cicatricial entropion" affecting the right upper eyelid. This typically occurs following conditions like chemical burns, trachoma, or chronic blepharitis that lead to conjunctival scarring. The physician's notes should clearly indicate the laterality (right) and the specific eyelid (upper).

• Differentiate from spastic or involutional entropion; this code is specifically for cicatricial etiology.
• Ensure the documentation specifies "right upper eyelid" to avoid laterality or eyelid errors.
• Code any associated corneal complications (e.g., corneal abrasion, ulcer) separately.
