ICD-10 Code H02.522 – Blepharophimosis right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.522 – Blepharophimosis right lower eyelid
What it is
H02.522 identifies a narrowed opening of the right lower eyelid. Use it when the chart specifically documents blepharophimosis affecting that side and eyelid.
Clinical signs
Findings may include a visibly shortened eyelid fissure, reduced eyelid aperture, or congenital eyelid narrowing. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents blepharophimosis of the right lower eyelid, whether congenital or acquired, and laterality is clear. It is appropriate when the note distinguishes this finding from ptosis, entropion, or other eyelid disorders. Check documentation if the record is incomplete.
Do not use for
Do not use this code for generalized blepharophimosis without laterality or for other eyelid abnormalities such as ptosis alone. Do not assign it if the right lower eyelid is not specifically documented.
Coding tip
Verify both the side and the exact eyelid before coding; if the note is ambiguous, query for clarification.
