ICD-10 Code H02.525 – Blepharophimosis left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.525 – Blepharophimosis left lower eyelid
What it is
H02.525 identifies a narrowed opening of the left lower eyelid. Use it when documentation specifies blepharophimosis affecting that eyelid, meaning the eyelid fissure is abnormally small.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include a visibly reduced palpebral fissure and eyelid narrowing on the left lower side, sometimes noted during eye or facial examination.
When to use this code
Use this code when the provider documents blepharophimosis limited to the left lower eyelid. It is appropriate for congenital or acquired narrowing only if the record clearly identifies that eyelid and laterality. If the note is nonspecific, check documentation.
Do not use for
Do not use this code for general ptosis, entropion, or eyelid droop without blepharophimosis. Also avoid it when the laterality or eyelid location is not documented; check documentation.
Coding tip
Confirm both the side and the exact eyelid before assigning H02.525.
