ICD-10 Code H83.90 – Unspecified disease of inner ear, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.90 – Unspecified disease of inner ear, unspecified ear
What it is
This code identifies a disorder of the inner ear when the specific condition is not documented and the affected ear is not specified. Use it when the record confirms an inner ear problem but does not name a more precise diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Inner ear disorders may present with vertigo, imbalance, hearing changes, tinnitus, or nonspecific ear-related complaints, but you should code only what is actually documented.
When to use this code
Use H83.90 when the clinician documents an unspecified inner ear disease and does not identify a clearer diagnosis such as Ménière disease, labyrinthitis, or another named disorder. It also fits when the ear laterality is not recorded. If the note is vague, check documentation before assigning a more specific code.
Do not use for
Do not use this code when the chart names a specific inner ear condition or provides a more precise diagnosis code. Do not assign it for external ear, middle ear, or nonspecific dizziness without documented inner ear disease.
Coding tip
Query for laterality and a specific diagnosis whenever possible; unspecified codes should be a last resort.
