ICD-10 Code H61.003 – Unspecified perichondritis of external ear, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.003 – Unspecified perichondritis of external ear, bilateral
What it is
This code identifies inflammation of the cartilage covering both external ears, with no further cause or type specified. Use it when documentation states bilateral perichondritis of the external ear without more detail.
Clinical signs
Typical findings include ear pain, redness, swelling, and tenderness over the auricle. Clinical features vary; refer to documentation when the record does not clearly confirm bilateral involvement.
When to use this code
Use H61.003 when the clinician documents perichondritis affecting both external ears and does not name an organism, trauma, or other specific cause. It also fits when the note says “unspecified” or gives only general inflammation of the auricle. Check documentation if laterality or site is unclear.
Do not use for
Do not use this code for infections limited to the ear canal, pinna cellulitis, or otitis externa. If the record identifies a specific cause or another ear diagnosis, code that condition instead.
Coding tip
Verify both laterality and the exact anatomic site in the note before assigning H61.003.
