2026 ICD-10-CM Diagnosis Code H61.011 – Acute perichondritis of right external ear
What it is
This code identifies an acute infection and inflammation of the cartilage covering the right external ear. Use it when documentation specifies the right side and an acute perichondritis diagnosis.
Clinical signs
Typical findings include a painful, swollen, and tender external ear with redness over the cartilaginous portion. Clinical features vary; refer to documentation for confirmed laterality and acuity.
When to use this code
Use H61.011 when the provider documents acute perichondritis involving the right external ear. It may appear in notes describing auricular cartilage infection, localized ear inflammation, or right-sided perichondrial involvement. Verify that the record supports acute disease and the right ear.
Do not use for
Do not use this code for unspecified ear infection, otitis externa, or left-sided perichondritis. Check documentation if the location or acuity is not clearly stated.
Coding tip
Always confirm both laterality and “acute” in the provider note before assigning H61.011.
