Trichiasis without entropion right eye, unspecified eyelid

This code describes a condition where the eyelashes of the right eye are misdirected and grow inwards, rubbing against the surface of the eye, without an inward turning of the eyelid itself. This can cause irritation, foreign body sensation, and potential damage to the cornea or conjunctiva.

Use this code when documentation specifies trichiasis affecting the right eye, and explicitly states that entropion is not present. This code is appropriate for cases where the specific eyelid (upper or lower) is not documented.

• Differentiate carefully between trichiasis with and without entropion; the presence of entropion changes the code.
• Always specify laterality (right, left, bilateral) when documented.
• If the specific eyelid (upper or lower) is known, a more specific code should be used.
