ICD-10 Code H02.059 – Trichiasis without entropion unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.059 – Trichiasis without entropion unspecified eye, unspecified eyelid
What it is
H02.059 identifies trichiasis without entropion when the affected eye and eyelid are not specified. Use it for misdirected eyelashes that rub the eye, but the lid is not turned inward.
Clinical signs
Typical findings include foreign-body sensation, tearing, redness, and irritation from lashes touching the ocular surface. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents trichiasis and specifically states there is no entropion. It also fits when the note does not identify the eye or eyelid involved. If laterality is documented, choose the more specific code instead.
Do not use for
Do not use this code for entropion with trichiasis or for eyelid disorders that are not causing lash misdirection. Check documentation if the record names a different eye condition.
Coding tip
Confirm both “without entropion” and unspecified laterality before assigning H02.059.
