ICD-10 Code H60.551 – Acute reactive otitis externa, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.551 – Acute reactive otitis externa, right ear
What it is
H60.551 identifies an acute inflammatory reaction of the external ear canal in the right ear. Use this code when the provider documents reactive otitis externa limited to the right side.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include ear canal redness, swelling, tenderness, and discomfort, with symptoms centered in the right external ear.
When to use this code
Use H60.551 when the record clearly states acute reactive otitis externa affecting the right ear. It is appropriate when laterality is documented and the condition is described as reactive, not simply nonspecific otitis externa. If the note does not specify the right ear, check documentation.
Do not use for
Do not use this code for left or bilateral otitis externa, or when the documentation only says otitis externa without “reactive” and right-ear laterality. Check documentation if the diagnosis is unclear.
Coding tip
Verify both the acute/reactive wording and right-ear laterality before assigning H60.551.
