ICD-10 Code H02.20A – Unspecified lagophthalmos right eye, upper and lower eyelids (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.20A – Unspecified lagophthalmos right eye, upper and lower eyelids
What it is
This code identifies lagophthalmos of the right eye when both upper and lower eyelids are involved and the cause is not further specified. It means the eyelids do not close fully, leaving the eye exposed.
Clinical signs
Typical findings include incomplete eyelid closure, visible sclera during attempted closure, and exposure-related ocular irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record documents lagophthalmos affecting the right eye with unspecified cause and involvement of both eyelids. It is appropriate when the provider notes incomplete closure but does not identify a more specific etiology. Check documentation if laterality or eyelid involvement is unclear.
Do not use for
Do not use this code if the chart specifies a different cause, such as facial nerve palsy or eyelid surgery-related lagophthalmos. Do not assign it when the condition is on the left eye or bilateral without right-eye specification.
Coding tip
Confirm laterality and whether the upper, lower, or both eyelids are involved before coding.
