C71.6 - Malignant neoplasm of cerebellum
| ICD-10: | C71.6 |
| Short Description: | Malignant neoplasm of cerebellum |
| Long Description: | Malignant neoplasm of cerebellum |
| Status: | Valid for Submission |
| Version: | ICD-10-CM 2023 |
| Code Classification: |
C71.6 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of cerebellum. 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 brain NEC cerebellopontine angle or Neoplasm, neoplastic brain NEC cerebellum NOS or Neoplasm, neoplastic cerebellopontine (angle) or Neoplasm, neoplastic cerebellum, cerebellar or Neoplasm, neoplastic vermis, cerebellum .
Approximate Synonyms
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Cerebellopontine angle tumor
- Classic medulloblastoma
- Glioblastoma multiforme of brain
- Low grade glioma of cerebellum
- Malignant glioma of cerebellum
- Malignant neoplasm of cerebellopontine angle
- Malignant neoplasm of cerebellum
- Malignant neoplasm of pons
- Medulloblastoma
- Medulloblastoma of cerebellum
- Primary glioblastoma multiforme of cerebellum
- Primary malignant neoplasm of cerebellum
Clinical Information
- Medulloblastoma-. a malignant neoplasm that may be classified either as a glioma or as a primitive neuroectodermal tumor of childhood (see neuroectodermal tumor, primitive). the tumor occurs most frequently in the first decade of life with the most typical location being the cerebellar vermis. histologic features include a high degree of cellularity, frequent mitotic figures, and a tendency for the cells to organize into sheets or form rosettes. medulloblastoma have a high propensity to spread throughout the craniospinal intradural axis.

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.
