ICD-10 Code H02.201 – Unspecified lagophthalmos right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.201 – Unspecified lagophthalmos right upper eyelid
What it is
This code identifies incomplete closure of the right upper eyelid when the cause is not specified. Use it when the chart documents lagophthalmos on the right upper lid but does not give a more detailed diagnosis.
Clinical signs
Typical findings include the eyelid not fully closing, especially during blinking or sleep. Clinical features vary; refer to documentation for any associated exposure symptoms or underlying eyelid dysfunction.
When to use this code
Use H02.201 when the provider documents unspecified lagophthalmos limited to the right upper eyelid. It fits notes describing incomplete lid closure without a stated cause, laterality beyond the right upper lid, or a more specific subtype. If documentation is unclear, check documentation before coding.
Do not use for
Do not use this code if the record identifies a different eyelid, both eyelids, or a more specific lagophthalmos type. Also avoid it when the documentation only mentions eye irritation or exposure without confirming lagophthalmos.
Coding tip
Match the exact laterality and eyelid location in the provider note before assigning this code.
