ICD-10 Code H02.223 – Mechanical lagophthalmos right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.223 – Mechanical lagophthalmos right eye, unspecified eyelid
What it is
This code identifies incomplete closure of the right eyelid caused by a mechanical problem. Use it when the right eye cannot fully close because of a structural or physical eyelid issue, and the eyelid is not otherwise specified.
Clinical signs
You may see exposed sclera, incomplete blinking, eye dryness, irritation, or tearing. Clinical features vary; refer to documentation.
When to use this code
Use H02.223 when the record states mechanical lagophthalmos affecting the right eye and does not specify the eyelid further. It fits cases where an eyelid abnormality, mass, scarring, or other mechanical factor prevents full closure. Check documentation if the cause or eyelid detail is unclear.
Do not use for
Do not use this code for lagophthalmos from facial nerve palsy or other non-mechanical causes. If the documentation identifies a different eyelid laterality or a more specific eyelid disorder, code that instead.
Coding tip
Confirm laterality and whether the chart says mechanical cause before assigning H02.223.
