Code Description

ICD-10 C71.0 is a billable code used to indicate a diagnosis of malignant neoplasm of cerebrum, except lobes and ventricles.

Key Diagnostic Point:

C71.0 refers to malignant tumors located in the cerebrum, excluding the lobes and ventricles. These tumors can arise from various cell types, including glial cells, neurons, and other supporting tissues. The clinical presentation often includes neurological deficits, seizures, and cognitive changes, depending on the tumor's location and size. Imaging studies such as MRI and CT scans are crucial for diagnosis, revealing the tumor's size, location, and characteristics. Molecular markers, including IDH mutations and 1p/19q co-deletion status, play a significant role in the classification and prognosis of these tumors. Treatment typically involves a multidisciplinary approach, including surgery, radiation therapy, and chemotherapy, tailored to the tumor type and patient condition. Accurate coding is essential for appropriate treatment reimbursement and tracking of cancer statistics.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Variety of tumor types and subtypes within the cerebrum
  • Need for precise documentation of tumor location and characteristics

  • Potential for overlapping symptoms with other CNS conditions

Audit Risk Factors

  • Inadequate documentation of tumor type and location
  • Failure to include imaging and molecular marker results
  • Misclassification of tumor grade or stage
  • Lack of clarity in treatment plans and outcomes
