ICD-10 Code H61.20 – Impacted cerumen, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.20 – Impacted cerumen, unspecified ear
What it is
H61.20 identifies impacted cerumen, or earwax, in an unspecified ear. Use it when documentation confirms wax blockage but does not name the left or right ear.
Clinical signs
Common findings include a visible wax plug, reduced hearing, ear fullness, or discomfort. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states impacted cerumen and laterality is not documented. It also fits encounters for earwax removal or evaluation when the provider does not specify which ear is affected.
If the note identifies the right or left ear, choose the laterality-specific code instead. Check documentation if the chart only mentions cerumen without clear impaction.
Do not use for
Do not use H61.20 for non-impacted cerumen or for ear symptoms without confirmed wax blockage. Check documentation when another ear disorder better explains the visit.
Coding tip
Verify laterality before assigning H61.20, because unspecified ear should be used only when the record truly omits side.
