ICD-10 Code H02.055 – Trichiasis without entropion left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.055 – Trichiasis without entropion left lower eyelid
What it is
H02.055 identifies eyelashes growing inward on the left lower eyelid without inward turning of the eyelid margin. Use it when the problem is lash misdirection, not entropion.
Clinical signs
Typical findings include lashes rubbing the eye, irritation, tearing, redness, or foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents trichiasis limited to the left lower eyelid and specifically states there is no entropion. It may be supported by exam findings of misdirected lashes causing ocular surface irritation. If laterality or eyelid location is unclear, check documentation.
Do not use for
Do not use H02.055 if the eyelid is turned inward, because that is entropion. Do not assign it for nonspecific eyelash disorders or when the affected side is not the left lower eyelid.
Coding tip
Verify both laterality and the absence of entropion in the note before assigning H02.055.
