C71.7 - Malignant neoplasm of brain stem

Version 2023
ICD-10:C71.7
Short Description:Malignant neoplasm of brain stem
Long Description:Malignant neoplasm of brain stem
Status: Valid for Submission
Version:ICD-10-CM 2023
Code Classification:
  • Neoplasms (C00–D48)
    • Malignant neoplasms of eye, brain and other parts of central nervous system (C69-C72)
      • Malignant neoplasm of brain (C71)

C71.7 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of brain stem. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

The following anatomical sites found in the Table of Neoplasms reference this diagnosis code given the correct histological behavior: Neoplasm, neoplastic basis pedunculi ; Neoplasm, neoplastic brain NEC choroid plexus ; Neoplasm, neoplastic brain NEC medulla oblongata ; Neoplasm, neoplastic brain NEC midbrain ; Neoplasm, neoplastic brain NEC peduncle ; Neoplasm, neoplastic brain NEC pons ; Neoplasm, neoplastic brain NEC stem ; etc

Tabular List of Diseases and Injuries

The Tabular List of Diseases and Injuries is a list of ICD-10 codes, organized "head to toe" into chapters and sections with coding notes and guidance for inclusions, exclusions, descriptions and more. The following references are applicable to this diagnosis code:


Inclusion Terms

Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a 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:

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.
