Code Description

ICD-10 C70.1 is a billable code used to indicate a diagnosis of malignant neoplasm of spinal meninges.

Key Diagnostic Point:

Malignant neoplasm of the spinal meninges refers to a cancerous growth that originates in the protective membranes surrounding the spinal cord. This condition can arise from primary tumors of the meninges or can be a result of metastasis from other malignancies. Symptoms may include back pain, neurological deficits, and signs of increased intracranial pressure. Diagnosis typically involves imaging studies such as MRI or CT scans, which can reveal the presence of tumors, their size, and their impact on surrounding structures. Treatment options may include surgical resection, radiation therapy, and chemotherapy, depending on the tumor's characteristics and the patient's overall health. Molecular markers may also be evaluated to guide treatment decisions and prognostication. Neurological function can be significantly affected, necessitating a multidisciplinary approach to management, including neurology, oncology, and rehabilitation services.
