ICD-10 Code H61.019 – Acute perichondritis of external ear, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.019 – Acute perichondritis of external ear, unspecified ear
What it is
This code identifies an acute infection and inflammation of the ear cartilage and surrounding tissue when the affected ear is not specified. It is used for perichondritis involving the external ear, not the ear canal.
Clinical signs
Typical findings include a painful, swollen, red external ear with tenderness over the cartilage. Clinical features vary; refer to documentation for whether the pinna, auricle, or nearby soft tissue is involved.
When to use this code
Use H61.019 when the record documents acute perichondritis of the external ear and does not identify the side. This fits encounters describing an infected, inflamed ear cartilage condition without a more specific laterality. If documentation is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for otitis externa, cellulitis of the ear, or chronic perichondritis unless the provider specifically documents acute perichondritis. Do not assume laterality when the chart does not state it.
Coding tip
Confirm that the provider names the external ear cartilage condition and whether the ear side is known before coding.
