ICD-10 Code H02.20 – Unspecified lagophthalmos (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.20 – Unspecified lagophthalmos
What it is
H02.20 identifies lagophthalmos when the eyelids cannot fully close, but the cause or side is not specified. Use it when documentation confirms incomplete eyelid closure without further detail.
Clinical signs
Typical findings include visible eyelid gap on attempted closure and possible exposure of the eye surface. Clinical features vary; refer to documentation.
When to use this code
Use H02.20 when the record states lagophthalmos or incomplete eyelid closure and does not identify the underlying cause. It also fits cases where laterality is not documented. If the note names a specific disorder causing the problem, code that condition instead.
Do not use for
Do not use this code for eyelid paralysis, facial nerve palsy, or other documented causes of incomplete closure when a more specific diagnosis is available. Check documentation.
Coding tip
Query for laterality and etiology before assigning H02.20.
