Malignant neoplasm of cerebrum, except lobes and ventricles

This code signifies a primary cancerous tumor originating within the cerebrum, excluding those specifically located in the cerebral lobes (frontal, parietal, temporal, occipital) or the cerebral ventricles. It represents a malignant growth within the main part of the brain responsible for higher functions.

Apply this code when documentation clearly indicates a primary malignant neoplasm of the cerebrum, and the specific lobe or ventricular involvement is not specified or is explicitly ruled out. This is appropriate for diagnoses such as glioblastoma multiforme or astrocytoma when the precise cerebral location is generalized.

• Ensure the documentation specifies "malignant" and "primary" to differentiate from benign or metastatic tumors.
• Carefully review operative reports and pathology findings for precise tumor location within the cerebrum.
• Avoid using this code if a more specific cerebral lobe (e.g., frontal lobe) or ventricular involvement is documented; instead, use the appropriate subcategory.
