ICD-10 Code H94.03 – Acoustic Neuritis in Infectious and Parasitic Diseases Classified Elsewhere, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H94.03 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere, bilateral
What it is
H94.03 identifies bilateral acoustic neuritis linked to an infectious or parasitic disease classified elsewhere. Use it when the hearing nerve involvement is documented as secondary to another underlying infection.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include bilateral hearing loss, tinnitus, or vestibular complaints when the auditory nerve is affected.
When to use this code
Use H94.03 when the record clearly states bilateral acoustic neuritis and ties it to an infectious or parasitic cause coded elsewhere. You should also code the underlying infection or parasitic disease separately, when documented.
Do not use for
Do not use this code for unspecified hearing loss, isolated tinnitus, or noninfectious auditory nerve disorders. Check documentation if the bilateral involvement or infectious cause is not explicit.
Coding tip
Verify both laterality and the underlying infectious diagnosis before assigning H94.03.
