ICD-10 Code H02.222 – Mechanical lagophthalmos right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.222 – Mechanical lagophthalmos right lower eyelid
What it is
H02.222 identifies incomplete closure of the right lower eyelid caused by a mechanical problem, such as scarring, mass effect, or tissue distortion. The eyelid cannot close fully, leaving the eye exposed.
Clinical signs
Common findings include visible gap or poor apposition of the right lower lid, exposure of the ocular surface, and symptoms of irritation or dryness. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states mechanical lagophthalmos affecting the right lower eyelid and the cause is structural or obstructive. It fits documentation of lid scarring, tumor, edema, or other mechanical interference. You should code the documented laterality exactly.
Do not use for
Do not use this code for paralytic lagophthalmos, unspecified eyelid closure problems, or left-sided conditions. Check documentation if the note does not clearly identify a mechanical cause.
Coding tip
Verify both the mechanical cause and right lower eyelid laterality before assigning H02.222.
