ICD-10 Code H60.592 – Other noninfective acute otitis externa, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.592 – Other noninfective acute otitis externa, left ear
What it is
This code identifies an acute inflammation of the left external ear canal that is not caused by infection. Use it when documentation specifies a noninfective cause and the left ear is affected.
Clinical signs
Typical findings may include ear canal pain, redness, swelling, itching, or tenderness with manipulation of the outer ear. Clinical features vary; refer to documentation.
When to use this code
Use H60.592 when the record states acute otitis externa in the left ear and clearly indicates a noninfective etiology, such as irritation or dermatitis. You should also use it when the clinician documents “other noninfective” otitis externa and no infectious cause is described.
Check laterality carefully. If the note does not specify the left ear, or if infection is documented, this code may not apply.
Do not use for
Do not use this code for infectious otitis externa or for chronic conditions unless the documentation supports an acute, noninfective process. Do not assume laterality; check documentation.
Coding tip
Verify both the noninfective cause and left-ear laterality before assigning H60.592.
