Senile entropion of left upper eyelid

This code signifies an inward turning of the margin of the left upper eyelid due to age-related changes, causing the eyelashes to rub against the cornea and conjunctiva. This condition is typically progressive and can lead to irritation, foreign body sensation, tearing, and potential corneal damage.

Apply this code when documentation explicitly states senile entropion affecting the left upper eyelid. Supporting documentation should include a physical exam noting the inward turning of the eyelid margin and the specific laterality and location (left upper).

• Ensure the documentation specifies "senile" entropion; other causes of entropion (e.g., spastic, cicatricial) have different codes.
• Verify laterality (left) and eyelid (upper) are clearly documented to avoid incorrect coding.
• Distinguish from ectropion, which is an outward turning of the eyelid margin.
