If you will refer for ICD-9 Manual index for neuroma, it is directing to, see also Neoplasm. In Neoplasm table, you will be getting under Nerve--cranial (any) benign 225.1 i.e acoustic neuroma (slow-growing tumor of the nerve).

ICD 225.1 is correct but acoustic neuroma is neoplasm of the VIII cranial nerve but here it is talking about the lower cranial nerve (which are from IX TO XII). So acoustic neuroma should not be mentioned here.

Two points to consider first - 1) Neuroma is a benign neoplasm. 2) Lower cranial nerves (CN) are -- Glossopharyngeal, Vagus, Accessory, Hypoglossal.

Now check in ICD index. The main term NEUROMA will ask you to check under NEOPLASM, By Site. In NEOPLASM, you can find "Cranial (any)" leading to 225.1 under column "benign". Here Cranial means "any" cranial nerve (upper I-VIII, or lower IX-XII). Still, to be sure, you check the names of lower CN under the same term "Neoplasm > Nerve". 3 out of 4 lower CN (Glossopharyngeal, Vagus, Hypoglossal) all are assigned 225.1.

So, the exact code should be 225.1
