Valid for Submission
C79.49 is a billable code used to specify a medical diagnosis of secondary malignant neoplasm of other parts of nervous system. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C79.49 might also be used to specify conditions or terms like disorder of olfactory nerve, disseminated retinitis, finding addressing invasion of optic nerve by tumor, finding addressing invasion of optic nerve by tumor, finding addressing invasion of optic nerve by tumor, finding addressing invasion of optic nerve by tumor, etc
The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: acoustic nerve ; arachnoid ; arachnoid spinal ; auditory nerve ; cauda equina ; chiasma opticum ; choroid ; etc
