ICD-10 Code H02.239 – Paralytic lagophthalmos unspecified eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.239 – Paralytic lagophthalmos unspecified eye, unspecified eyelid
What it is
H02.239 identifies paralysis-related inability to close the eyelids completely, with the eye and eyelid not otherwise specified. Use it when documentation states paralytic lagophthalmos but does not identify a side or more precise eyelid detail.
Clinical signs
Typical findings include incomplete eyelid closure, visible sclera during attempted closure, and exposure of the ocular surface. Clinical features vary; refer to documentation for the specific cause and laterality.
When to use this code
Use this code when the record clearly documents paralytic lagophthalmos and does not specify right, left, or a more detailed eyelid diagnosis. It may appear in notes describing facial nerve dysfunction, incomplete eye closure, or exposure risk. Check documentation if the cause is uncertain.
Do not use for
Do not use this code for voluntary eyelid closure problems, nonspecific eye irritation, or conditions with documented laterality when a more specific code is available. Do not assume paralysis without provider documentation.
Coding tip
Before assigning H02.239, verify that the note states paralytic lagophthalmos and that no eye or eyelid side is documented.
