Spastic entropion of left eye, unspecified eyelid

This code describes an inward turning of the lower eyelid margin of the left eye, specifically due to muscle spasm, where the exact eyelid (upper or lower) is not specified in the documentation. This spastic inversion causes the eyelashes to rub against the cornea and conjunctiva, leading to irritation and potential corneal damage.

Use this code when documentation clearly indicates spastic entropion affecting the left eye, but the specific eyelid (upper or lower) is not explicitly stated. This is appropriate for conditions like blepharospasm or other involuntary muscle contractions causing the eyelid to turn inward.

• Ensure documentation specifies "spastic" entropion; otherwise, consider other entropion codes (e.g., senile, cicatricial).
• If the specific eyelid (upper or lower) is documented, use the more precise code (H02.01- for senile, H02.02- for spastic, H02.03- for cicatricial).
• Always code laterality (left, right, bilateral) if specified in the clinical notes.
