ICD-10 Code H60.43 – Cholesteatoma of external ear, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H60.43 – Cholesteatoma of external ear, bilateral
What it is
H60.43 identifies cholesteatoma affecting both external ears. It refers to a localized keratinizing lesion in the external auditory canal, documented as bilateral.
Clinical signs
Typical findings include a keratin debris mass, canal obstruction, or chronic irritation in both ears. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents cholesteatoma of the external ear in both ears. It fits confirmed bilateral disease, including cases noted on otoscopic exam or in specialist records. If the record only says “ear cholesteatoma” or does not specify laterality, check documentation before coding.
Do not use for
Do not use it for middle ear cholesteatoma or for a unilateral external ear lesion. If the chart describes another ear disorder without cholesteatoma, this code is not appropriate.
Coding tip
Confirm both the anatomic site and bilateral laterality in the provider note before assigning H60.43.
