2026 ICD-10-CM Diagnosis Code H02.122 – Mechanical ectropion of right lower eyelid
What it is
This code identifies outward turning of the right lower eyelid caused by a mechanical factor, such as scarring, mass effect, or tissue changes. The lid no longer rests normally against the eye.
Clinical signs
Common findings include visible eversion of the lower lid, tearing, irritation, redness, and exposure of the conjunctiva. Clinical features vary; refer to documentation.
When to use this code
Use H02.122 when the provider documents mechanical ectropion affecting the right lower eyelid. Code it when the cause is described as mechanical, not simply age-related or paralytic. You should match the laterality and eyelid specified in the record.
Do not use for
Do not use this code for ectropion of the left eyelid, upper eyelid, or unspecified side. Do not use it when the documentation supports another type of ectropion or the cause is not mechanical.
Coding tip
Check the note for both laterality and the stated cause before assigning H02.122.
