ICD-10 Code H02.235 – Paralytic lagophthalmos left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.235 – Paralytic lagophthalmos left lower eyelid
What it is
Use this code for paralysis-related inability of the left lower eyelid to close fully. It describes lagophthalmos caused by nerve or muscle dysfunction affecting eyelid closure.
Clinical signs
Typical findings include incomplete eyelid closure, exposed ocular surface, and possible dryness or irritation. Clinical features vary; refer to documentation.
When to use this code
Assign H02.235 when the record specifically documents paralytic lagophthalmos of the left lower eyelid. Use it for cases where eyelid closure is impaired due to paralysis, not simply swelling or mechanical lid problems. Check documentation for laterality and cause.
Do not use for
Do not use this code for nonparalytic lagophthalmos or unspecified eyelid closure problems. If the chart does not identify the left lower eyelid or paralysis, check documentation.
Coding tip
Verify both paralysis and left lower eyelid laterality before coding H02.235.
