ICD-10 Code H02.2 – Lagophthalmos (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.2 – Lagophthalmos
What it is
Lagophthalmos means the eyelids cannot close completely. This incomplete closure can leave the eye exposed and may affect the cornea.
Clinical signs
Typical findings include visible gap between the eyelids on closure, incomplete blinking, and eye exposure. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents lagophthalmos, whether due to facial nerve weakness, eyelid scarring, or another stated cause. Code it when incomplete eyelid closure is the diagnosis being addressed. Check documentation for laterality or associated conditions if recorded.
Do not use for
Do not use this code for general dry eye, conjunctivitis, or eyelid swelling unless lagophthalmos is specifically documented. Do not guess the diagnosis from exposure symptoms alone.
Coding tip
Confirm that the note states incomplete eyelid closure, and code any documented cause separately when supported.
