ICD-10 Code H61.21 – Impacted cerumen, right ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.21 – Impacted cerumen, right ear
What it is
This code identifies a blockage of earwax in the right ear canal. It is used when the cerumen is impacted enough to require clinical attention or removal.
Clinical signs
Patients may report ear fullness, reduced hearing, or discomfort on the right side. Clinical features vary; refer to documentation for visible wax obstruction or related exam findings.
When to use this code
Use H61.21 when the provider documents impacted cerumen specifically in the right ear. It fits office visits for evaluation, irrigation, or manual removal when the impaction is the reason for care. If the record does not specify laterality, check documentation.
Do not use for
Do not use this code for cerumen in the left ear, bilateral impaction, or simple excess wax without impaction. Check documentation if the note only mentions earwax buildup.
Coding tip
Capture laterality exactly as documented, because cerumen codes are side-specific.
