ICD-10 Code H02.52 – Blepharophimosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.52 – Blepharophimosis
What it is
Blepharophimosis is a congenital narrowing of the eyelid opening, usually affecting both eyes. It can limit the visible palpebral fissure and may be part of a broader eyelid malformation pattern.
Clinical signs
Typical findings include short horizontal eyelid fissures, drooping upper lids, and reduced lid opening. Clinical features vary; refer to documentation if associated facial or ocular abnormalities are noted.
When to use this code
Use H02.52 when the provider documents blepharophimosis as the diagnosed condition, especially in congenital or structural eyelid cases. You may also use it when the record clearly identifies the narrowed eyelid opening without a more specific alternative diagnosis. Check documentation if laterality or a related syndrome is described.
Do not use for
Do not use this code for simple ptosis, eyelid edema, or temporary eyelid closure problems. If the chart describes another eyelid disorder instead, code that condition rather than blepharophimosis.
Coding tip
Code the documented eyelid malformation exactly as stated and confirm whether the provider notes a congenital syndrome or additional eyelid defect.
