ICD-10 Code H83.93 – Unspecified disease of inner ear, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.93 – Unspecified disease of inner ear, bilateral
What it is
This code identifies a bilateral inner ear disorder when the specific disease is not documented. Use it when the record confirms inner ear involvement on both sides but does not name a more precise condition.
Clinical signs
Clinical features vary; refer to documentation. Inner ear disorders may present with vertigo, dizziness, imbalance, hearing changes, or tinnitus, but you should code only what is supported in the chart.
When to use this code
Use H83.93 when the provider documents an unspecified disease of the inner ear affecting both ears and no more specific diagnosis is available. It may fit incomplete assessments, referral notes, or encounters where the workup is ongoing. Check documentation for laterality and specificity.
Do not use for
Do not use this code if the condition is unilateral, a more specific inner ear diagnosis is documented, or the problem is clearly outside the inner ear. Avoid using it for nonspecific dizziness without a documented inner ear disorder.
Coding tip
Query for the exact inner ear diagnosis and laterality before defaulting to H83.93.
