Malignant neoplasm of spinal cord

This code signifies a primary cancerous tumor originating within the spinal cord tissue itself. It describes the presence of malignant cells forming a growth that can compress or invade the spinal cord, leading to neurological deficits.

Apply this code when documentation clearly indicates a primary malignant neoplasm of the spinal cord. This diagnosis is typically confirmed through imaging studies (MRI, CT) and often biopsy results. Use it for the initial diagnosis and subsequent treatment of this specific type of cancer.

• Differentiate from secondary (metastatic) spinal cord tumors, which are coded differently.
• Ensure the documentation specifies "spinal cord" and not just "spine" (which could imply vertebrae).
• Always sequence this code according to official ICD-10-CM guidelines, often as the primary diagnosis.
