C72.5Malignant neoplasm of other and unspecified cranial nerves

C72.5 is the ICD-10-CM diagnosis code for malignant neoplasm of other and unspecified cranial nerves. It belongs to category C72 (malignant neoplasm of spinal cord, cranial nerves and other parts of central nervous system), block C69-C72 (malignant neoplasms of eye, brain and other parts of central nervous system) and chapter 2 (neoplasms). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within C72, choose C72.5 (other and unspecified cranial nerves) only when documentation doesn't support a more specific option: spinal cord (C72.0), cauda equina (C72.1), olfactory nerve (C72.2), optic nerve (C72.3), acoustic nerve (C72.4) and central nervous system, unspecified (C72.9).

To report this condition, pick the subcode that matches the documentation: C72.50 (nerve) and C72.59 (nerves).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
