ICD-10 Code H61.009 – Unspecified perichondritis of external ear, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.009 – Unspecified perichondritis of external ear, unspecified ear
What it is
This code identifies inflammation of the tissue around the cartilage of the external ear when the ear side is not specified. Use it when documentation confirms perichondritis but does not name right or left ear.
Clinical signs
Typical findings include ear pain, redness, swelling, and tenderness over the pinna. Clinical features vary; refer to documentation for the affected ear and any associated injury, infection, or abscess.
When to use this code
Use H61.009 when the provider documents perichondritis of the external ear and does not specify laterality. It also fits cases where the note says “unspecified ear” or the side cannot be determined from the record. Check documentation if another ear disorder is described more precisely.
Do not use for
Do not use this code for otitis externa, auricular cellulitis, or ear pain without a documented diagnosis of perichondritis. If the record identifies a right or left ear, code the specified side instead.
Coding tip
Verify laterality first; unspecified codes are appropriate only when the chart truly lacks right-or-left detail.
