ICD-10 Code H61.11 – Acquired deformity of pinna (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.11 – Acquired deformity of pinna
What it is
H61.11 identifies an acquired change in the shape or structure of the external ear pinna. Use it when the deformity developed after birth rather than being present from congenital causes.
Clinical signs
Typical findings include visible distortion, flattening, thickening, or other abnormal contour of the pinna. Clinical features vary; refer to documentation for the exact ear involvement and cause.
When to use this code
Use this code when the record clearly documents an acquired deformity of the pinna and no more specific diagnosis is provided. It may apply after trauma, surgery, inflammation, or other acquired change if the provider documents deformity as the condition being treated or evaluated.
Do not use for
Do not use H61.11 for congenital ear malformations or for nonspecific ear pain, swelling, or infection without deformity. Check documentation if the record describes a mass, laceration, or other primary lesion instead.
Coding tip
Code the deformity only when the provider documents it as acquired; if the cause is stated, capture that diagnosis too when appropriate.
