ICD-10 Code H60.599 – Other noninfective acute otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.599 – Other noninfective acute otitis externa, unspecified ear
What it is
This code identifies an acute inflammation of the external ear canal that is not caused by infection, when the affected ear is not specified. Use it for short-term noninfective otitis externa documented by the clinician.
Clinical signs
Typical findings include ear canal irritation, pain, itching, redness, or swelling. Clinical features vary; refer to documentation, and confirm that the condition is noninfective rather than bacterial, fungal, or viral.
When to use this code
Use H60.599 when the record states acute otitis externa is noninfective and does not identify right or left ear. It also fits cases described as allergic, irritant, or other noninfective external ear canal inflammation, if no infection is documented.
Do not use for
Do not use this code for infectious otitis externa, chronic otitis externa, or when the provider specifies a right or left ear code instead. Check documentation if the cause or laterality is unclear.
Coding tip
Always verify both noninfective status and unspecified laterality before assigning H60.599.
