Code Description

ICD-10 C71.4 is a billable code used to indicate a diagnosis of malignant neoplasm of occipital lobe.

Key Diagnostic Point:

C71.4 refers to a malignant neoplasm located in the occipital lobe of the brain, which is responsible for visual processing. These tumors can arise from glial cells (gliomas), meningeal tissue (meningiomas), or metastasize from other primary cancers. Symptoms may include visual disturbances, headaches, seizures, and cognitive changes, depending on the tumor's size and location. Imaging studies such as MRI or CT scans are crucial for diagnosis, revealing the tumor's size, location, and potential involvement of surrounding structures. Molecular markers, including IDH1/2 mutations and 1p/19q co-deletion status, can provide insights into tumor behavior and guide treatment decisions. Neurological function may be significantly impacted, necessitating a multidisciplinary approach for management, including neurosurgery, radiation therapy, and chemotherapy. Accurate coding is essential for appropriate treatment planning and reimbursement.

Frequently Asked Questions

What imaging studies are necessary for coding C71.4?

MRI or CT scans are essential for diagnosing and documenting the presence of a malignant neoplasm in the occipital lobe. Ensure that the imaging reports are included in the patient's medical record.

How do molecular markers influence coding for C71.4?

Molecular markers can provide additional information regarding the tumor's behavior and treatment response, which should be documented to support the coding of C71.4.
