ICD-10 Code H02.524 – Blepharophimosis left upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.524 – Blepharophimosis left upper eyelid
What it is
H02.524 identifies a narrowed opening of the left upper eyelid. Use it when the documentation states blepharophimosis affecting that eyelid specifically.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include a visibly short palpebral fissure and reduced eyelid aperture on the left upper side.
When to use this code
Use this code when the provider documents blepharophimosis of the left upper eyelid, whether as a primary diagnosis or a noted congenital eyelid anomaly. It may also apply when laterality is clearly specified in the record. Check documentation if the note only says blepharophimosis without side.
Do not use for
Do not use this code for nonspecific ptosis, general eyelid malformations, or blepharophimosis on another side. If the record does not identify the left upper eyelid, check documentation.
Coding tip
Confirm both laterality and eyelid level in the provider note before assigning H02.524.
