ICD-10 Code H93.13 – Tinnitus, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.13 – Tinnitus, bilateral
What it is
H93.13 identifies tinnitus heard in both ears. Use it when the record documents bilateral ringing, buzzing, or similar sound perception without an external source.
Clinical signs
Patients commonly report persistent or intermittent noise perception in both ears. Clinical features vary; refer to documentation, especially when the note distinguishes bilateral symptoms from unilateral or unspecified tinnitus.
When to use this code
Use H93.13 when the clinician explicitly documents tinnitus affecting both ears. It is appropriate for outpatient visits, problem lists, and follow-up encounters where bilateral tinnitus remains the active diagnosis. If the laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for unilateral tinnitus or when the chart only says “tinnitus” without laterality. Check documentation if the symptom is secondary to another clearly documented ear disorder.
Coding tip
Code laterality exactly as documented; if the note does not confirm bilateral involvement, do not assume H93.13.
