Clinical Information

• Adult Intracranial Meningioma|Adult Brain Meningioma

  an intracranial meningioma that occurs during adulthood.

• Anaplastic (Malignant) Intracranial Meningioma

  an anaplastic meningioma that arises within the cranial cavity.

• Benign Intracranial Meningioma|Benign neoplasm of cerebral meninges

  a grade i, slowly growing meningioma within the cranial cavity.

• Childhood Intracranial Meningioma|Brain Meningioma|Childhood Brain Meningioma

  an intracranial meningioma that occurs during childhood.

• Intracranial Meningioma

  a meningioma that arises within the cranial cavity.

Convert C70.0 to ICD-9-CM

• ICD-9-CM Code: 192.1 - Mal neo cerebral mening
  Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Table of Neoplasms

This code is referenced 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.

Patient Education

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 drugs or other substances that attack cancer cells with less harm to normal cells. Many people get a combination of treatments.
