ICD-10 Code H94.0 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H94.0 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere
What it is
Use this code for acoustic neuritis, meaning inflammation or injury affecting the auditory nerve, when it is linked to an infectious or parasitic disease classified elsewhere. It identifies the ear/nerve complication, not the underlying infection.
Clinical signs
Clinical features vary; refer to documentation. Typical findings may include hearing loss, tinnitus, or reduced sound perception, with symptoms tied to an infectious or parasitic condition.
When to use this code
Assign H94.0 when the record clearly states acoustic neuritis and links it to an infection or parasitic disease coded elsewhere. Use it when the provider documents the nerve involvement as a complication rather than a primary ear disorder.
Code the underlying infectious or parasitic condition first or separately, as directed by the record and coding rules. If the cause is unclear, check documentation before selecting this code.
Do not use for
Do not use it for nonspecific hearing loss, tinnitus alone, or ear symptoms without documented acoustic neuritis. Do not use it when the condition is not tied to an infectious or parasitic disease.
Coding tip
Always capture the underlying infection or parasite code in addition to H94.0 when the documentation supports a causal relationship.
