ICD-10 Code H02.026 – Mechanical entropion of left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.026 – Mechanical entropion of left eye, unspecified eyelid
What it is
This code identifies inward turning of the left eyelid caused by a mechanical factor, such as scarring, mass effect, or tissue distortion. The specific eyelid is not further specified in the record.
Clinical signs
Typical findings include eyelid inversion with lashes rubbing the eye, tearing, irritation, redness, or foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use H02.026 when the provider documents mechanical entropion affecting the left eye and does not identify the upper or lower eyelid. This is appropriate when the cause is described as mechanical or secondary to another local process. Check documentation if the note only says entropion without laterality or mechanism.
Do not use for
Do not use this code for congenital, spastic, or cicatricial entropion unless the provider specifically documents a mechanical cause. Do not assign it if the eyelid involved is not the left eye.
Coding tip
Confirm both laterality and the mechanical etiology in the provider note before coding.
