2021 ICD-10-CM Code C79.32

Secondary malignant neoplasm of cerebral meninges

Version 2021

Valid for Submission

C79.32 is a billable diagnosis code used to specify a medical diagnosis of secondary malignant neoplasm of cerebral meninges. The code C79.32 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.

The ICD-10-CM code C79.32 might also be used to specify conditions or terms like malignant neoplasm of cerebral meninges, metastatic malignant neoplasm of meninges or secondary malignant neoplasm of cerebral meninges.

The following anatomical sites found in the Table of Neoplasms apply to this 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

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code C79.32 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Table of Neoplasms

The code C79.32 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

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.
