ICD-10 Code H61.90 – Disorder of external ear, unspecified, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.90 – Disorder of external ear, unspecified, unspecified ear
What it is
This code identifies a disorder affecting the outer ear when the provider does not specify the exact condition or side. Use it for an external ear problem that is documented only in general terms.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note visible outer-ear abnormality, discomfort, swelling, or irritation, but the exact diagnosis is not stated.
When to use this code
Use H61.90 when the chart says “disorder of external ear” without naming a more specific condition or ear laterality. It also fits when the provider documents an outer-ear issue but leaves the diagnosis unspecified. If the note later identifies the exact disorder or ear, code that instead.
Do not use for
Do not use this code if the condition is clearly a specific external ear diagnosis, such as cerumen impaction or otitis externa. Also avoid it when the documentation identifies the right or left ear.
Coding tip
Check documentation for a more specific external ear diagnosis and laterality before defaulting to H61.90.
