ICD-10 Code H61.22 – Impacted cerumen, left ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H61.22 – Impacted cerumen, left ear
What it is
H61.22 identifies a buildup of earwax that blocks the left ear canal. Use it when the cerumen is impacted enough to require clinical attention or removal.
Clinical signs
Patients may report reduced hearing, ear fullness, or discomfort on the left side. Clinical features vary; refer to documentation, especially if the exam notes an obstructing cerumen plug.
When to use this code
Use this code when the record clearly states impacted cerumen in the left ear. It is appropriate when the provider documents cerumen impaction, wax obstruction, or removal of a left-sided cerumen plug.
Code from the documented ear side, not from symptoms alone. If the note does not specify laterality or only mentions earwax without impaction, check documentation.
Do not use for
Do not use H61.22 for routine earwax presence without impaction. Do not use it when the right ear or both ears are documented instead.
Coding tip
Always confirm laterality and the word “impacted” in the note before assigning H61.22.
