Malignant neoplasm of spinal cord

This code signifies a primary cancerous tumor originating within the spinal cord tissue itself. These are rare but serious growths that can compress the spinal cord, leading to neurological deficits. Symptoms often include pain, weakness, numbness, and bowel/bladder dysfunction.

Apply this code when documentation clearly indicates a primary malignant neoplasm located within the spinal cord. This diagnosis is typically confirmed through imaging studies (e.g., MRI) and often a biopsy. Use this code for the initial diagnosis and subsequent treatment encounters related to the primary tumor.

• Differentiate from metastatic tumors to the spinal cord, which would be coded as secondary malignancies.
• Ensure the documentation specifies "malignant" and "spinal cord" to avoid confusion with benign tumors or tumors of the vertebrae.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated neurological deficits.
