Spastic entropion of right lower eyelid

This code signifies an inward turning of the right lower eyelid margin due to muscle spasm, causing the eyelashes to rub against the cornea. This involuntary contraction of the orbicularis oculi muscle can lead to ocular irritation, foreign body sensation, and potential corneal damage.

Apply this code when documentation explicitly states spastic entropion affecting the patient's right lower eyelid. This condition is often observed in older adults or following ocular inflammation/irritation. Supporting documentation should detail the specific eyelid affected and the spastic nature of the entropion.

• Differentiate from cicatricial entropion (H02.01-) which is caused by scarring.
• Ensure laterality (right vs. left) and eyelid (upper vs. lower) are clearly documented.
• Consider additional codes for any associated complications, such as corneal abrasion (T85.698A) if present.
