ICD-10 Code H94.01 – Acoustic Neuritis in Infectious and Parasitic Diseases Classified Elsewhere, Right Ear (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H94.01 – Acoustic neuritis in infectious and parasitic diseases classified elsewhere, right ear
What it is
This code identifies acoustic neuritis affecting the right ear when the cause is an infectious or parasitic disease classified elsewhere. Use it when documentation specifies the right side and links the neuritis to another underlying condition.
Clinical signs
Clinical features vary; refer to documentation. Typical records may note hearing disturbance, ear-related nerve involvement, or symptoms attributed to an infectious or parasitic process affecting the auditory pathway.
When to use this code
Use H94.01 when the clinician documents acoustic neuritis in the right ear and states it is due to an infection or parasitic disease coded elsewhere. Code the underlying disease first or additionally, as directed by the record and coding rules.
Apply it only when the right ear is clearly identified. If laterality is missing, or the condition is described differently, check documentation before assigning this code.
Do not use for
Do not use this code for nonspecific hearing loss, tinnitus, or ear pain without documented acoustic neuritis. Do not use it when the cause is not infectious or parasitic, or when the affected ear is not the right ear.
Coding tip
Verify both laterality and the underlying infectious or parasitic diagnosis before coding H94.01.
