ICD-10 Code H83.9 – Unspecified disease of inner ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.9 – Unspecified disease of inner ear
What it is
H83.9 identifies an inner ear disorder when the record does not name a more specific diagnosis. Use it for documented inner ear disease affecting hearing or balance, but without enough detail to assign a narrower code.
Clinical signs
Clinical features vary; refer to documentation. Inner ear disorders may present with hearing loss, tinnitus, vertigo, dizziness, or imbalance, but the chart must support an inner ear problem rather than a middle or external ear condition.
When to use this code
Use H83.9 when the clinician documents an unspecified inner ear disease and no more specific diagnosis is available. It also fits when the note confirms inner ear involvement, but the type, cause, or laterality is not stated. Check documentation before defaulting to this code.
Do not use for
Do not use H83.9 if the record identifies a specific inner ear disorder, such as Ménière disease or another named condition. Do not use it for hearing loss, vertigo, or ear pain alone unless the provider links them to an unspecified inner ear disease.
Coding tip
Query for specificity when the note says “inner ear disorder” but does not name the exact diagnosis.
