ICD-10 Code H02.21C – Cicatricial lagophthalmos, bilateral, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.21C – Cicatricial lagophthalmos, bilateral, upper and lower eyelids
What it is
This code identifies lagophthalmos caused by scarring of both upper and lower eyelids on both sides. The eyelids cannot close fully because scar tissue restricts movement.
Clinical signs
Common findings include incomplete eyelid closure, visible sclera when the eyes are closed, and exposure-related irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents cicatricial lagophthalmos affecting both upper and lower eyelids bilaterally. You should also use it when scarring is the stated cause of the incomplete closure. Check documentation if the laterality or eyelid involvement is not explicit.
Do not use for
Do not use this code for lagophthalmos without scarring, or when only one eyelid or one eye is involved. If the cause is not cicatricial, choose the more accurate documented diagnosis.
Coding tip
Confirm both laterality and the scar-related cause before assigning H02.21C.
