ICD-10 Code H60.559 – Acute reactive otitis externa, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.559 – Acute reactive otitis externa, unspecified ear
What it is
This code identifies an acute inflammatory reaction affecting the external ear canal, with the ear not further specified. Use it when documentation supports reactive otitis externa but does not identify the right or left ear.
Clinical signs
Typical findings include ear canal inflammation, pain, itching, swelling, or tenderness. Clinical features vary; refer to documentation if the record does not clearly describe the reactive nature or affected ear.
When to use this code
Use H60.559 when the provider documents acute reactive otitis externa and does not specify laterality. It also fits when the note confirms otitis externa as a reactive process, but no more detailed ear designation is available. Check documentation if the cause or site is unclear.
Do not use for
Do not use this code for chronic otitis externa, otitis media, or nonspecific ear pain alone. If the record names a different ear disorder or laterality, select the more specific code.
Coding tip
Always verify whether the documentation names the right ear, left ear, or unspecified ear before assigning H60.559.
