ICD-10 Code H02.20C – Unspecified lagophthalmos, bilateral, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.20C – Unspecified lagophthalmos, bilateral, upper and lower eyelids
What it is
This code identifies lagophthalmos affecting both eyes, with incomplete closure of the upper and lower eyelids. “Unspecified” means the record does not state a cause or more detailed subtype.
Clinical signs
Typical findings include visible eyelid gap when the eyes should be closed and exposure of the ocular surface. Clinical features vary; refer to documentation.
When to use this code
Use this code when documentation states bilateral lagophthalmos and does not specify a more precise cause or eyelid subtype. It also fits cases where both upper and lower lids are involved on both sides. Check documentation if the record mentions facial nerve palsy, trauma, or a postprocedural cause.
Do not use for
Do not use it when lagophthalmos is documented as unilateral or when a more specific bilateral code is available. Avoid this code if the chart identifies a different eyelid disorder instead.
Coding tip
Confirm laterality and whether the upper, lower, or both eyelids are involved before assigning H02.20C.
