ICD-10 Code H02.123 – Mechanical ectropion of right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.123 – Mechanical ectropion of right eye, unspecified eyelid
What it is
Use this code for outward turning of the right eyelid caused by a mechanical factor, such as a mass, scar, or other local pull. The eyelid involved is not otherwise specified.
Clinical signs
Typical findings include eyelid eversion, exposed conjunctiva, tearing, irritation, and possible redness. Clinical features vary; refer to documentation.
When to use this code
Assign H02.123 when the record clearly states mechanical ectropion affecting the right eye and does not identify the upper or lower eyelid. Use it when the provider documents a mechanical cause, not a paralytic or involutional form. Check documentation if the eyelid is specified elsewhere.
Do not use for
Do not use this code for ectropion of the left eye, both eyes, or when the eyelid type is documented more specifically. Do not use it if the condition is paralytic, cicatricial, or congenital unless the record supports mechanical ectropion.
Coding tip
Capture the exact laterality and eyelid detail from the note; if the eyelid is named, code the more specific option instead of H02.123.
