ICD-10 Code H61.012 – Acute perichondritis of left external ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.012 – Acute perichondritis of left external ear
What it is
H61.012 identifies acute inflammation of the cartilage and surrounding tissue of the left external ear. Use it when documentation specifies perichondritis affecting the left pinna or auricular cartilage.
Clinical signs
Typical findings include a painful, swollen, red left external ear, often with tenderness over the cartilage. Clinical features vary; refer to documentation for laterality and whether the condition is acute.
When to use this code
Use this code when the provider documents acute perichondritis of the left ear, including notes describing infection or inflammation of the auricular cartilage. It also fits encounters where the diagnosis is confirmed and laterality is clearly stated. Check documentation if the record only says ear pain or cellulitis.
Do not use for
Do not use this code for nonspecific external ear pain, otitis externa, or right-sided or bilateral disease. If the chart does not clearly identify perichondritis of the left external ear, check documentation.
Coding tip
Always verify laterality and acute status in the provider note before assigning H61.012.
