ICD-10 Code H02.22A – Mechanical lagophthalmos right eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.22A – Mechanical lagophthalmos right eye, upper and lower eyelids
What it is
This code identifies incomplete closure of the right eyelids caused by a mechanical problem. The upper and lower lids do not meet fully, leaving the eye exposed.
Clinical signs
Typical findings include visible eyelid gap, incomplete blinking, and exposure of the ocular surface. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states mechanical lagophthalmos affecting the right eye with both upper and lower eyelids involved. It fits documentation describing lid closure failure from a structural or mechanical cause, not from facial nerve weakness. Check documentation if the cause or laterality is unclear.
Do not use for
Do not use this code for lagophthalmos from paralysis, spasm, or unspecified eyelid closure problems. Do not assign it if the chart does not clearly identify the right eye and mechanical cause.
Coding tip
Confirm laterality and the mechanical cause in the note before coding H02.22A.
