ICD-10 Code H60.549 – Acute eczematoid otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.549 – Acute eczematoid otitis externa, unspecified ear
What it is
This code identifies an acute, eczema-like inflammation of the external ear canal when the affected ear is not specified. Use it for short-term otitis externa with eczematous changes documented by the clinician.
Clinical signs
Findings commonly include itching, redness, scaling, and irritation of the ear canal. Clinical features vary; refer to documentation for laterality, severity, and any associated drainage or swelling.
When to use this code
Use H60.549 when the record clearly states acute eczematoid otitis externa and does not identify right or left ear. It also fits when the provider documents eczema-type otitis externa without further detail. If the note names another ear condition, check documentation before assigning this code.
Do not use for
Do not use this code for nonspecific otitis externa, chronic ear canal dermatitis, or infectious otitis externa unless the provider documents eczematoid disease. Check documentation if the ear side is specified or another diagnosis is primary.
Coding tip
Confirm that “eczema,” “eczematoid,” and “acute otitis externa” are documented together before coding H60.549.
