Malignant neoplasm of temporal lobe

This code signifies a primary cancerous tumor originating within the temporal lobe of the brain. These neoplasms are characterized by uncontrolled cell growth and have the potential to invade surrounding brain tissue and metastasize. Patients may present with symptoms such as seizures, memory impairment, language difficulties, or auditory hallucinations.

Use this code when documentation clearly indicates a primary malignant neoplasm located specifically in the temporal lobe. This diagnosis is typically confirmed through imaging studies (e.g., MRI, CT scan) and often a biopsy. The physician's final diagnosis should explicitly state "malignant neoplasm of the temporal lobe."

• Ensure the documentation specifies "malignant" and "temporal lobe" to avoid coding benign or unspecified brain tumors.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter.
• Review pathology reports and operative notes for definitive confirmation of malignancy and precise tumor location.
