ICD-10-CM Code C70.0

Malignant neoplasm of cerebral meninges

Version 2020 Billable Code Neoplasm Malignant Primary

Valid for Submission

C70.0 is a billable code used to specify a medical diagnosis of malignant neoplasm of cerebral meninges. The code is valid for the year 2020 for the submission of HIPAA-covered transactions. The ICD-10-CM code C70.0 might also be used to specify conditions or terms like diffuse leptomeningeal melanocytosis, diffuse melanosis of meninges, malignant meningioma of meninges of brain, malignant meningioma of optic nerve sheath, malignant neoplasm of cerebral arachnoid mater, malignant neoplasm of cerebral dura mater, etc

The following anatomical sites found in the Table of Neoplasms apply to this code given the correct histological behavior: arachnoid cerebral ; brain NEC meninges ; cerebrum, cerebra (cortex) (hemisphere) (white matter) meninges ; cranial (fossa, any) meninges ; dura (cranial) (mater) cerebral ; falx (cerebella) (cerebri) ; meninges brain ; etc

Table of Neoplasms

The code C70.0 is included in the table of neoplasms by anatomical site. For each site there are six possible code numbers according to whether the neoplasm in question is malignant, benign, in situ, of uncertain behavior, or of unspecified nature. The description of the neoplasm will often indicate which of the six columns is appropriate.

Where such descriptors are not present, the remainder of the Index should be consulted where guidance is given to the appropriate column for each morphological (histological) variety listed. However, the guidance in the Index can be overridden if one of the descriptors mentioned above is present.

Information for Patients


Brain Tumors

A brain tumor is a growth of abnormal cells in the tissues of the brain. Brain tumors can be benign, with no cancer cells, or malignant, with cancer cells that grow quickly. Some are primary brain tumors, which start in the brain. Others are metastatic, and they start somewhere else in the body and move to the brain.

Brain tumors can cause many symptoms. Some of the most common are

  • Headaches, often in the morning
  • Nausea and vomiting
  • Changes in your ability to talk, hear, or see
  • Problems with balance or walking
  • Problems with thinking or memory
  • Feeling weak or sleepy
  • Changes in your mood or behavior
  • Seizures

Doctors diagnose brain tumors by doing a neurologic exam and tests including an MRI, CT scan, and biopsy. Treatment options include watchful waiting, surgery, radiation therapy, chemotherapy, and targeted therapy. Targeted therapy uses substances that attack cancer cells without harming normal cells. Many people get a combination of treatments.
