C71.5 is a billable ICD-10 code used to specify a medical diagnosis of malignant neoplasm of cerebral ventricle. 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 ventricle (floor) ; Neoplasm, neoplastic cerebrum, cerebra (cortex) (hemisphere) (white matter) ventricle ; Neoplasm, neoplastic choroid plexus ; Neoplasm, neoplastic ependyma (brain) ; Neoplasm, neoplastic plexus choroid ; Neoplasm, neoplastic ventricle (cerebral) (floor) (lateral) (third) ; etc
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Choroid plexus carcinoma
- Malignant neoplasm of cerebral ventricles
- Malignant neoplasm of floor of cerebral ventricle
- Malignant tumor of choroid plexus
- Primary ependymoma of brain ventricle
- Primary malignant neoplasm of cerebral ventricle
- Tumor of choroid plexus
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:
Type 1 ExcludesType 1 Excludes
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Index to Diseases and Injuries References
The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10 code(s). The following references for this diagnosis code are found in the injuries and diseases index:
- - Papilloma - See Also: Neoplasm, benign, by site;
- - choroid plexus (lateral ventricle) (third ventricle) - D33.0

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.

»ventricle (cerebral) (floor) (lateral) (third)
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
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.
