ICD-10 Code H60.313 – Diffuse Otitis Externa, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.313 – Diffuse otitis externa, bilateral
What it is
This code identifies diffuse inflammation and infection of the external ear canal in both ears. Use it when the documentation specifies bilateral diffuse otitis externa.
Clinical signs
Typical findings include ear canal pain, itching, redness, swelling, and tenderness that may worsen with movement of the outer ear. Clinical features vary; refer to documentation.
When to use this code
Use H60.313 when the provider documents diffuse otitis externa affecting both ear canals. It fits bilateral external ear canal inflammation without a more specific subtype. If laterality is not clearly stated, check documentation before assigning this code.
Do not use for
Do not use this code for localized otitis externa, otitis media, or unspecified ear infection. If the record does not confirm bilateral involvement, choose the more appropriate documented code.
Coding tip
Always verify laterality and the term “diffuse” in the note before coding H60.313.
