ICD-10 Code C72.41 – Malignant neoplasm of right acoustic nerve (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code C72.41 – Malignant neoplasm of right acoustic nerve
What it is
This code identifies a malignant tumor involving the right acoustic nerve, also called the vestibulocochlear nerve. Use it when documentation specifically states cancer of the right acoustic nerve.
Clinical signs
Clinical features vary; refer to documentation. Possible findings include unilateral hearing changes, tinnitus, balance problems, or other neurologic symptoms, depending on tumor extent and location.
When to use this code
Use C72.41 when the provider documents a malignant neoplasm arising from, or involving, the right acoustic nerve. It may also apply when pathology, imaging, or operative notes clearly support this site. If the record only says “acoustic nerve tumor” without laterality or malignant behavior, check documentation.
Do not use for
Do not use this code for benign acoustic neuroma or unspecified nerve tumors. Also avoid it when the malignancy is documented on the left side or when the site is not clearly the right acoustic nerve.
Coding tip
Verify laterality and malignant behavior in the final provider documentation before assigning C72.41.
