ICD-10 Code H02.233 – Paralytic lagophthalmos right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.233 – Paralytic lagophthalmos right eye, unspecified eyelid
What it is
This code identifies incomplete closure of the right eyelid caused by facial nerve weakness or paralysis. Use it when the record specifies the right eye and does not identify a particular eyelid.
Clinical signs
Typical findings include inability to fully close the right eye, visible scleral exposure, and possible dryness or irritation. Clinical features vary; refer to documentation.
When to use this code
Use H02.233 when the provider documents paralytic lagophthalmos affecting the right eye and the eyelid is not further specified. It may appear in notes describing facial palsy, eye exposure, or incomplete lid closure. Code only when the documentation clearly supports paralysis-related lagophthalmos.
Do not use for
Do not use this code for nonparalytic eyelid closure problems or lagophthalmos without right-eye laterality. Check documentation if the eyelid, cause, or side is unclear.
Coding tip
Confirm both laterality and paralysis-related etiology before assigning H02.233.
