Malignant neoplasm of cerebral meninges
ICD-10 C70.0 is a billable code used to indicate a diagnosis of malignant neoplasm of cerebral meninges.
Malignant neoplasm of the cerebral meninges refers to a cancerous growth that originates in the protective membranes covering the brain and spinal cord, known as the meninges. This type of tumor can arise from various cell types within the meninges, including meningeal cells, and may exhibit aggressive behavior, leading to significant neurological deficits. Symptoms often include headaches, seizures, cognitive changes, and focal neurological deficits, depending on the tumor's location. Diagnosis typically involves imaging studies such as MRI or CT scans, which can reveal the presence of a mass effect, edema, or enhancement patterns indicative of malignancy. Molecular markers, such as IDH mutations and 1p/19q co-deletion status, may assist in determining tumor type and prognosis. Treatment often involves a multidisciplinary approach, including surgical resection, radiation therapy, and chemotherapy, tailored to the tumor's characteristics and the patient's overall health. Monitoring neurological function is crucial, as these tumors can significantly impact cognitive and motor abilities.
Detailed neurological assessments, imaging results, and treatment plans must be documented.
Patients presenting with new-onset seizures, headaches, or cognitive decline.
Neurologists must ensure that all neurological deficits are documented to support the diagnosis.
Comprehensive treatment plans, including surgical notes and pathology reports.
Patients undergoing chemotherapy or radiation therapy for meningeal tumors.
Oncologists should document molecular markers and treatment responses to support coding.
Used when a malignant meningeal tumor is surgically removed.
Operative report detailing the procedure and findings.
Neurosurgeons must document the extent of resection and any complications.
MRI is the preferred imaging modality for diagnosing malignant neoplasms of the cerebral meninges, as it provides detailed images of soft tissue and can reveal mass effects, edema, and enhancement patterns.
