ICD-10 Code H02.529 – Blepharophimosis unspecified eye, unspecified lid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.529 – Blepharophimosis unspecified eye, unspecified lid
What it is
This code identifies blepharophimosis affecting an unspecified eye and unspecified eyelid. It means the eyelid opening is abnormally narrow, but the record does not specify laterality or which lid is involved.
Clinical signs
Common findings include a small palpebral fissure and reduced eyelid opening. Clinical features vary; refer to documentation for laterality, lid involvement, and any associated congenital eye or eyelid abnormalities.
When to use this code
Use H02.529 when the provider documents blepharophimosis but does not identify the eye or eyelid. It is appropriate when the chart lacks laterality or further anatomic detail needed for a more specific code.
If the note describes a congenital eyelid narrowing without additional specification, this code may fit. Check documentation carefully before assigning it, especially if a unilateral, bilateral, upper, or lower lid code is available.
Do not use for
Do not use this code when the record specifies the eye or eyelid, because a more exact code may apply. Do not use it for general ptosis or other eyelid disorders unless blepharophimosis is documented.
Coding tip
Confirm laterality and lid detail in the ophthalmology note before defaulting to this unspecified code.
