ICD-10 Code H02.12 – Mechanical ectropion of eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.12 – Mechanical ectropion of eyelid
What it is
Mechanical ectropion is outward turning of the eyelid caused by a pulling force or mass, not by simple age-related laxity. It usually affects the lower lid and can expose the eye surface.
Clinical signs
Look for lid eversion, tearing, irritation, and poor eyelid apposition to the globe. Clinical features vary; refer to documentation for the underlying cause, such as swelling, scarring, or a lesion.
When to use this code
Use H02.12 when the provider documents mechanical ectropion of the eyelid. This fits cases where a tumor, edema, scar, or other external factor is pulling the lid outward. Code the documented cause separately when instructed and supported.
Do not use for
Do not use this code for congenital or involutional ectropion unless the record specifically says mechanical. If documentation only says eyelid malposition or irritation, check documentation before assigning H02.12.
Coding tip
Confirm the note states “mechanical ectropion” and identify the cause, because the underlying condition may need additional coding.
