ICD-10 Code H83.09 – Labyrinthitis, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H83.09 – Labyrinthitis, unspecified ear
What it is
H83.09 identifies labyrinthitis affecting an unspecified ear. Use it when the chart documents inflammation of the inner ear balance and hearing organs, but does not name the right or left side.
Clinical signs
Typical findings include vertigo, dizziness, nausea, imbalance, and sometimes hearing symptoms. Clinical features vary; refer to documentation, especially when the record does not clearly confirm laterality or specific cause.
When to use this code
Use this code when the provider documents labyrinthitis and does not specify which ear is involved. It also fits encounters where the diagnosis is recorded as unspecified ear or when laterality is not available in the note.
Choose the more specific code if the record identifies right or left ear, or if another diagnosis better explains the symptoms. Check documentation before coding related vestibular disorders or hearing loss alone.
Do not use for
Do not use H83.09 when the chart specifies right or left ear, because a laterality-specific code is more accurate. Do not assign it for nonspecific dizziness without documented labyrinthitis.
Coding tip
Verify laterality and the exact provider wording; if the ear is named, code it specifically rather than defaulting to unspecified.
