ICD-10 Code H83.92 – Unspecified disease of left inner ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.92 – Unspecified disease of left inner ear
What it is
H83.92 identifies a disorder of the left inner ear when the record does not specify the exact diagnosis. Use it for documented inner ear disease limited to the left side, but with insufficient detail for a more specific code.
Clinical signs
Clinical features vary; refer to documentation. Commonly reported inner ear findings may include vertigo, imbalance, hearing changes, tinnitus, or other vestibular complaints affecting the left ear.
When to use this code
Use this code when the provider documents a left inner ear disease but does not name the condition, such as labyrinthine disorder or other nonspecific inner ear pathology. It may also fit incomplete charting after evaluation of left-sided ear symptoms. Do not assume a more specific diagnosis without clear documentation.
Do not use for
Do not use it for middle ear, external ear, or bilateral ear disorders. If the note identifies a specific inner ear condition, code that diagnosis instead.
Coding tip
Query for the exact left inner ear diagnosis whenever the documentation is vague or the laterality is unclear.
