ICD-10 Code H02.21 – Cicatricial lagophthalmos (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.21 – Cicatricial lagophthalmos
What it is
Cicatricial lagophthalmos means the eyelids cannot close fully because scarring has shortened or tightened the lid tissues. This incomplete closure can leave the eye exposed and vulnerable.
Clinical signs
Common findings include visible eyelid scarring, lid shortening, and incomplete eye closure, especially during sleep or blinking. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents lagophthalmos caused by cicatricial change, such as after trauma, surgery, burns, or chronic inflammation. Code it when the provider clearly links the incomplete eyelid closure to scarring. If the note only says “inability to close the eye,” check documentation for the cause.
Do not use for
Do not use this code for lagophthalmos from facial nerve palsy, eyelid paralysis, or simple eyelid retraction without scarring. Check documentation if the cause is not clearly cicatricial.
Coding tip
Confirm both the lagophthalmos and the scar-related cause in the chart before assigning H02.21.
