ICD-10 Code H02.124 – Mechanical ectropion of left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.124 – Mechanical ectropion of left upper eyelid
What it is
H02.124 identifies outward turning of the left upper eyelid caused by a mechanical factor, such as a mass, scarring, or tissue weight. This code describes the eyelid position problem, not the underlying cause.
Clinical signs
Typical findings include visible eversion of the left upper lid, poor eyelid apposition, and exposure of the eye surface. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record specifically documents mechanical ectropion affecting the left upper eyelid. It fits cases where an external or structural force is noted as the cause, and the laterality and upper-lid location are confirmed. Check documentation if the cause is not stated.
Do not use for
Do not use this code for unspecified ectropion, involutional ectropion, or ectropion of another eyelid. If the chart does not identify a mechanical cause, verify the diagnosis before coding.
Coding tip
Confirm both laterality and the mechanical nature of the ectropion in the provider note before assigning H02.124.
