ICD-10 Code H61.021 – Chronic perichondritis of right external ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.021 – Chronic perichondritis of right external ear
What it is
Use this code for long-lasting inflammation of the cartilage and surrounding tissue of the right outer ear. It identifies a chronic perichondritis process limited to the right external ear.
Clinical signs
Typical findings include persistent pain, tenderness, swelling, and redness of the right auricle. Clinical features vary; refer to documentation for chronicity and whether cartilage involvement is specifically noted.
When to use this code
Assign H61.021 when the record clearly documents chronic perichondritis affecting the right external ear. Use it for outpatient, inpatient, or specialist notes that specify the right side and a chronic course.
If the provider describes perichondritis without laterality or chronicity, check documentation before coding. You should code the documented condition as written, not infer the side or duration.
Do not use for
Do not use this code for acute perichondritis, nonspecific ear pain, or infections that do not involve the auricular cartilage. Check documentation if the diagnosis is cellulitis, otitis externa, or another ear disorder.
Coding tip
Confirm both chronicity and right-sided involvement in the note before assigning H61.021.
