ICD-10 Code H60.55 – Acute reactive otitis externa (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.55 – Acute reactive otitis externa
What it is
This code identifies acute reactive inflammation of the external ear canal. Use it when documentation specifically describes otitis externa as reactive and acute.
Clinical signs
Typical findings include ear canal redness, swelling, and pain, often with tenderness when the outer ear is touched. Clinical features vary; refer to documentation.
When to use this code
Assign this code when the clinician documents acute reactive otitis externa by name. Use it for encounters focused on external ear canal inflammation, not middle ear disease. If the note only says “ear pain” or “otitis,” check documentation before coding.
Do not use for
Do not use it for otitis media, chronic otitis externa, or nonspecific ear discomfort. If the record does not clearly support the reactive acute diagnosis, check documentation.
Coding tip
Code H60.55 only when the provider’s wording matches the diagnosis; do not infer “reactive” from symptoms alone.
