ICD-10 Code H93.3X3 – Disorders of bilateral acoustic nerves (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H93.3X3 – Disorders of bilateral acoustic nerves
What it is
This code identifies a disorder affecting both acoustic nerves, also called the vestibulocochlear nerves. Use it when the record documents bilateral nerve involvement rather than a general hearing complaint.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include bilateral hearing loss, tinnitus, imbalance, or abnormal auditory nerve testing when both sides are involved.
When to use this code
Use H93.3X3 when the provider specifically documents a bilateral acoustic nerve disorder, such as bilateral neuritis, neuropathy, or other bilateral nerve abnormality. Code it from the diagnosis statement or confirmed assessment, not from symptoms alone. If the note only says “hearing loss,” check documentation for a more specific diagnosis.
Do not use for
Do not use this code for unilateral acoustic nerve disorders or for nonspecific ear symptoms without documented nerve involvement. Check documentation if the chart only mentions tinnitus, dizziness, or sensorineural hearing loss.
Coding tip
Verify that “bilateral” and “acoustic nerve” are both documented before assigning H93.3X3.
