ICD-10 Code H02.052 – Trichiasis without entropion right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.052 – Trichiasis without entropion right lower eyelid
What it is
H02.052 identifies inward-growing eyelashes on the right lower eyelid without entropion. Use it when the eyelid margin is normal, but lashes rub the eye and cause irritation.
Clinical signs
Common findings include lash contact with the cornea or conjunctiva, foreign-body sensation, tearing, redness, and photophobia. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents trichiasis limited to the right lower eyelid and specifically states there is no entropion. It also fits follow-up visits for persistent lash misdirection affecting that eyelid. If laterality or eyelid is not documented, check documentation before assigning a code.
Do not use for
Do not use H02.052 if the eyelash problem is due to entropion, because that is a different diagnosis. Do not assign it for unspecified laterality or for other eyelids.
Coding tip
Confirm both laterality and the absence of entropion in the note before coding.
