ICD-10 Code H02.22B – Mechanical lagophthalmos left eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.22B – Mechanical lagophthalmos left eye, upper and lower eyelids
What it is
This code identifies incomplete closure of the left eyelids caused by a mechanical problem affecting both the upper and lower lids. The eye may remain partly exposed when the patient tries to close it.
Clinical signs
Common findings include visible gap in eyelid closure, exposed sclera, and difficulty fully closing the left eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states mechanical lagophthalmos of the left eye involving both upper and lower eyelids. It applies when the cause is mechanical, such as lid scarring, mass effect, or structural eyelid abnormality. Check documentation if the note does not clearly specify laterality or both lids.
Do not use for
Do not use it for paralysis-related lagophthalmos or unspecified eyelid closure problems. If the record does not confirm a mechanical cause, check documentation.
Coding tip
Verify left-sided involvement and that both upper and lower eyelids are affected before assigning H02.22B.
