ICD-10 Code H02.526 – Blepharophimosis left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.526 – Blepharophimosis left eye, unspecified eyelid
What it is
H02.526 identifies blepharophimosis affecting the left eye when the eyelid is not further specified. It means the eyelid opening is abnormally narrow, which can limit the visible palpebral fissure.
Clinical signs
Clinical features vary; refer to documentation. Commonly, you may see a shortened eyelid aperture and narrowing of the eye opening on the left side, with possible associated eyelid malposition noted in the record.
When to use this code
Use this code when the provider documents blepharophimosis of the left eye and does not specify the eyelid beyond that. It is appropriate for outpatient, consult, or problem-list documentation when the diagnosis is clearly established. If laterality or eyelid detail differs, code to the documented term.
Do not use for
Do not use it for generalized ptosis, eyelid edema, or nonspecific eye-opening complaints unless blepharophimosis is documented. If the chart does not confirm the left eye or the eyelid detail, check documentation.
Coding tip
Confirm laterality and wording exactly as documented; unspecified eyelid means you should not add a more specific eyelid code without support.
