ICD-10 Code H94.00 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere, unspecified ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H94.00 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere, unspecified ear
What it is
H94.00 identifies acoustic neuritis affecting the unspecified ear when the condition is classified elsewhere because of an underlying infectious or parasitic disease. Use it when the record links the ear nerve inflammation to another documented infection or parasitic illness.
Clinical signs
Clinical features vary; refer to documentation. Records may note hearing changes, ear-related discomfort, or other auditory nerve findings, but the key point is that the neuritis is associated with an infectious or parasitic cause.
When to use this code
Use H94.00 when the provider documents acoustic neuritis in the unspecified ear and states it is due to, or classified with, an infectious or parasitic disease. It is appropriate when laterality is not specified. If the cause or ear is unclear, check documentation before coding.
Do not use for
Do not use this code for nonspecific hearing loss, tinnitus, or ear pain without documented neuritis. Also avoid it when the condition is not linked to an infectious or parasitic disease, or when a more specific ear or cause code is documented.
Coding tip
Confirm both the infectious/parasitic linkage and the unspecified ear before assigning H94.00.
