ICD-10 Code H02.05 – Trichiasis without entropion (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.05 – Trichiasis without entropion
What it is
Trichiasis without entropion means the eyelashes are misdirected inward and rub against the eye, but the eyelid itself is not turned inward. Use this code when the lash problem is documented without entropion.
Clinical signs
Typical findings include eye irritation, foreign-body sensation, tearing, redness, and corneal or conjunctival irritation. Clinical features vary; refer to documentation.
When to use this code
Use H02.05 when the provider documents trichiasis and specifically states there is no entropion. It also fits cases described as inward-growing lashes, misdirected lashes, or lash-corneal irritation without eyelid inversion. Check documentation if the note is unclear.
Do not use for
Do not use this code when entropion is present or documented as the cause of the lash misdirection. If the record only says eyelid irritation or another eye disorder, confirm the diagnosis before coding.
Coding tip
Code the documented laterality and avoid assuming entropion when the provider does not state it.
