ICD-10 Code H02.523 – Blepharophimosis right eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.523 – Blepharophimosis right eye, unspecified eyelid
What it is
H02.523 identifies blepharophimosis affecting the right eye when the eyelid is not further specified. It refers to an abnormally narrow eyelid opening, which can limit the visible palpebral fissure.
Clinical signs
Typical findings include a shortened eyelid aperture and reduced horizontal opening of the eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents blepharophimosis in the right eye and does not specify upper or lower eyelid involvement. It is appropriate for congenital or acquired cases only when the record supports the diagnosis. If laterality or eyelid detail is clearer, code to the more specific documented option.
Do not use for
Do not use it for general ptosis, eyelid droop, or other eyelid malpositions unless blepharophimosis is explicitly documented. Check documentation.
Coding tip
Confirm both laterality and eyelid detail in the note before assigning H02.523.
