ICD-10 Code H02.232 – Paralytic lagophthalmos right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.232 – Paralytic lagophthalmos right lower eyelid
What it is
This code identifies inability to fully close the right lower eyelid because of paralysis. It reflects eyelid weakness that leaves the eye incompletely protected.
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
Use H02.232 when the record specifically documents paralytic lagophthalmos affecting the right lower eyelid. Choose it when the cause is paralysis rather than scarring, trauma, or simple eyelid laxity. If the note does not clearly identify the right lower eyelid, check documentation.
Do not use for
Do not use this code for nonparalytic lagophthalmos or general eyelid closure problems without paralysis. Do not assign it if the documentation points to a different eyelid or a different cause.
Coding tip
Verify laterality and that “paralytic” is explicitly documented before assigning H02.232.
