ICD-10 Code H60.33 – Swimmer’s Ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.33 – Swimmer’s ear
What it is
H60.33 identifies swimmer’s ear, an infection or inflammation of the outer ear canal. Use it when documentation specifically states this diagnosis.
Clinical signs
Typical findings include ear pain, tenderness when the outer ear is moved, itching, swelling, and canal redness or discharge. Clinical features vary; refer to documentation.
When to use this code
Use H60.33 when the provider documents swimmer’s ear or acute otitis externa affecting the external auditory canal. It fits cases with clear outer ear canal infection, especially after water exposure. Check documentation if laterality or acuity is specified elsewhere.
Do not use for
Do not use this code for middle ear infection, earwax buildup, or nonspecific ear pain without otitis externa. If the record does not support swimmer’s ear, check documentation.
Coding tip
Code only when the diagnosis is documented; if the note says otitis externa, verify whether swimmer’s ear is specifically identified.
