ICD-10 Code H93.1 – Tinnitus (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.1 – Tinnitus
What it is
Tinnitus is the perception of sound, such as ringing, buzzing, hissing, or roaring, without an external source. You use this code when the record documents tinnitus as the diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Patients commonly report persistent or intermittent ear noise, which may be unilateral or bilateral and may affect sleep, concentration, or hearing-related complaints.
When to use this code
Use H93.1 when the provider documents tinnitus as a current diagnosis, symptom, or reason for evaluation. It is appropriate when the chart identifies subjective ear noise without a more specific underlying disorder coded instead. Check documentation if tinnitus is described as part of another condition.
Do not use for
Do not use this code for hearing loss alone, ear pain, or dizziness without documented tinnitus. If the note identifies a specific cause or associated condition that should be coded instead, follow the provider’s documentation.
Coding tip
Assign H93.1 only when tinnitus is explicitly documented, and code any confirmed underlying cause separately when supported by the record.
