ICD-10 Code H02.053 – Trichiasis without entropion right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.053 – Trichiasis without entropion right eye, unspecified eyelid
What it is
This code identifies inward-growing eyelashes on the right eye without eyelid turning inward. The eyelid side is not specified, so you should use the code only when documentation does not identify the upper or lower lid.
Clinical signs
Typical findings include lash-corneal irritation, foreign-body sensation, tearing, redness, and possible corneal abrasion. Clinical features vary; refer to documentation for the exact eyelid involved and whether entropion is absent.
When to use this code
Use H02.053 when the provider documents trichiasis in the right eye and specifically states there is no entropion. It also fits cases where the eyelid is not identified as upper or lower. If documentation later specifies the lid, code more precisely.
Do not use for
Do not use this code if the right eye trichiasis is due to entropion, or if the affected eye is left or bilateral. Check documentation if the record names a specific eyelid or another eyelid disorder.
Coding tip
Confirm both laterality and the absence of entropion before assigning H02.053.
