Benign neoplasm of other specified sites of nervous system

This code represents a non-cancerous tumor originating from nervous system tissue in locations other than those specifically classified elsewhere (e.g., brain, spinal cord, cranial nerves). These benign neoplasms do not spread to other parts of the body but can cause symptoms due to compression or mass effect on surrounding structures.

Use this code when documentation specifies a benign neoplasm of a nervous system site not covered by more specific ICD-9-CM codes, such as peripheral nerves, autonomic ganglia, or other unspecified nervous system tissues. Supporting documentation should clearly state the benign nature of the tumor and its specific nervous system location.

• Ensure the documentation explicitly states "benign" and identifies a nervous system site not covered by more specific codes (e.g., 225.0-225.2).
• Avoid using this code if a more specific benign neoplasm code for the nervous system exists (e.g., benign neoplasm of brain, cranial nerves).
• Confirm the tumor is not metastatic; if malignant, a code from the 191-192 series or a secondary malignancy code would be appropriate.
