Malignant neoplasm of temporal lobe

This code signifies a primary cancerous tumor originating within the temporal lobe of the brain. This malignant growth is characterized by uncontrolled cell proliferation and has the potential to invade surrounding brain tissue or metastasize to distant sites.

Apply this code when documentation confirms a primary malignant neoplasm specifically located in the temporal lobe. Supporting documentation typically includes pathology reports, operative reports detailing tumor removal from the temporal lobe, or imaging reports (MRI, CT) explicitly identifying a malignant mass in this region.

• Ensure the documentation specifies "malignant" and "primary" to differentiate from benign tumors or secondary metastases.
• Verify the exact anatomical location within the brain; do not use for unspecified brain tumors or tumors in other lobes.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by any associated neurological deficits or complications.
