ICD-10 Code H02.224 – Mechanical lagophthalmos left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.224 – Mechanical lagophthalmos left upper eyelid
What it is
This code identifies incomplete closure of the left upper eyelid caused by a mechanical problem. The lid cannot fully close because of a physical obstruction, mass, scarring, or other local issue.
Clinical signs
Common findings include visible gap on eyelid closure, exposure of the eye surface, and difficulty blinking fully. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents mechanical lagophthalmos affecting the left upper eyelid and the cause is structural rather than neurologic. It may apply after trauma, surgery, scarring, or a local eyelid lesion. You should confirm laterality and that the problem is specifically mechanical.
Do not use for
Do not use this code for lagophthalmos from facial nerve palsy or other neurologic causes. Check documentation if the record does not clearly identify a mechanical cause or if the affected eyelid is not the left upper eyelid.
Coding tip
Verify both laterality and the mechanical cause in the note before assigning H02.224.
