Code Description

ICD-10 C71.2 is a billable code used to indicate a diagnosis of malignant neoplasm of temporal lobe.

Key Diagnostic Point:

C71.2 refers to a malignant neoplasm located in the temporal lobe of the brain, which is part of the central nervous system (CNS). Tumors in this region can arise from various cell types, including glial cells, neurons, and meningeal tissues. The temporal lobe is crucial for auditory processing, memory, and language comprehension, making tumors in this area particularly impactful on neurological function. Symptoms may include seizures, memory loss, auditory hallucinations, and changes in behavior. Imaging studies such as MRI and CT scans are essential for diagnosis, revealing the tumor's size, location, and potential involvement of surrounding structures. Molecular markers, such as IDH mutations and 1p/19q co-deletion status, can provide prognostic information and guide treatment decisions. Treatment typically involves a multidisciplinary approach, including surgery, radiation therapy, and chemotherapy, depending on the tumor's type and grade. Accurate coding of C71.2 is critical for appropriate reimbursement and tracking of CNS malignancies.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variability in tumor histology and grading
  • Need for precise localization within the temporal lobe
