Trichiasis without entropion unsp, unspecified eyelid

This code signifies the presence of trichiasis, a condition where eyelashes grow inwards and rub against the cornea or conjunctiva, causing irritation. Importantly, this specific code indicates that the trichiasis is not accompanied by entropion (inward turning of the eyelid margin) and the laterality of the affected eye and eyelid are not specified in the medical record.

Use this code when documentation clearly states trichiasis without mention of entropion, and the physician does not specify which eye (right, left, or bilateral) or which eyelid (upper, lower) is affected. This code is appropriate when the laterality is truly unknown or not documented.

• Avoid using this code if laterality (right, left, bilateral) or specific eyelid is documented; instead, choose a more specific code.
• Ensure the documentation explicitly rules out entropion, or at least does not mention its presence.
• Query the provider for laterality and specific eyelid if possible to allow for more precise coding.
