Code Classification

  • Neoplasms
    (C00–D49)
    • Malignant neoplasms of ill-defined, other secondary and unspecified sites
      (C76-C80)
      • Secondary malignant neoplasm of other and unspecified sites
        (C79)

C79.32 is a billable diagnosis code used to specify a medical diagnosis of secondary malignant neoplasm of cerebral meninges. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

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

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Malignant neoplasm of cerebral meninges
  • Metastatic malignant neoplasm of meninges
  • Metastatic malignant neoplasm to cerebral meninges

Clinical Classification

Convert C79.32 to ICD-9-CM

  • ICD-9-CM Code: 198.4 - Sec malig neo nerve NEC
    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.
