ICD-10 Code H02.22C – Mechanical lagophthalmos, bilateral, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.22C – Mechanical lagophthalmos, bilateral, upper and lower eyelids
What it is
This code identifies incomplete eyelid closure in both eyes caused by a mechanical problem affecting the upper and lower lids. The lids cannot fully meet, leaving the eye surface exposed.
Clinical signs
Common findings include visible gap on attempted closure, eyelid malposition, and exposure of the ocular surface. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents bilateral mechanical lagophthalmos involving both upper and lower eyelids. It is appropriate when the cause is structural or positional rather than neurologic. Check documentation for laterality and whether both lids are affected.
Do not use for
Do not use this code for unilateral lagophthalmos or for incomplete eyelid closure from facial nerve palsy. Do not assign it when the chart does not specify a mechanical cause.
Coding tip
Confirm both laterality and the mechanical etiology before coding, because missing details can change the ICD-10 selection.
