Code Description

ICD-10 C74.02 is a billable code used to indicate a diagnosis of malignant neoplasm of cortex of left adrenal gland.

Key Diagnostic Point:

C74.02 refers to a malignant neoplasm located in the cortex of the left adrenal gland. The adrenal glands, situated atop each kidney, are responsible for producing hormones that regulate metabolism, immune response, blood pressure, and stress responses. Malignant neoplasms of the adrenal cortex can lead to significant hormonal imbalances, resulting in conditions such as Cushing's syndrome, Conn's syndrome, or adrenal insufficiency. Symptoms may include hypertension, weight gain, fatigue, and abnormal glucose metabolism. Diagnosis typically involves imaging studies such as CT or MRI scans, along with biochemical tests to assess hormone levels. Treatment often requires surgical intervention, such as adrenalectomy, and may be followed by chemotherapy or radiation therapy depending on the tumor's characteristics. Accurate coding is essential for proper treatment planning and reimbursement, as well as for tracking outcomes in patients with adrenal malignancies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation between benign and malignant neoplasms
  • Need for precise documentation of tumor location and characteristics
  • Potential for multiple hormone-related conditions complicating diagnosis
  • Variability in treatment approaches based on tumor type and stage

Audit Risk Factors

  • Inadequate documentation of tumor characteristics
  • Failure to specify laterality (left vs. right)
  • Misclassification of benign versus malignant neoplasms
  • Lack of supporting lab results for hormone levels

Medical Specialties

Endocrinology

Documentation Requirements

Detailed hormone level assessments, imaging results, and clinical symptoms.

Common Clinical Scenarios

Patients presenting with symptoms of hormonal excess or deficiency, requiring evaluation of adrenal function.

Billing Considerations

Endocrinologists must ensure comprehensive documentation of hormonal assays and imaging studies to support the diagnosis.

Oncology

Documentation Requirements

Pathology reports, imaging studies, and treatment plans.

Common Clinical Scenarios

Patients diagnosed with adrenal tumors undergoing surgical or medical management.

Billing Considerations
