Code Description

ICD-10 C74.1 is a billable code used to indicate a diagnosis of malignant neoplasm of medulla of adrenal gland.

Key Diagnostic Point:

C74.1 refers to a malignant neoplasm located in the medulla of the adrenal gland, which is responsible for producing catecholamines such as epinephrine and norepinephrine. These hormones play a critical role in the body's response to stress, regulating heart rate, blood pressure, and metabolism. Malignant tumors in this area can lead to excessive hormone production, resulting in symptoms such as hypertension, palpitations, and anxiety. The diagnosis typically involves imaging studies like CT or MRI, along with biochemical tests to assess hormone levels. Treatment options may include surgical resection, chemotherapy, or radiation therapy, depending on the tumor's size, stage, and overall health of the patient. Accurate coding is essential for proper reimbursement and tracking of treatment outcomes, as well as for research purposes in understanding the epidemiology of adrenal malignancies.

Complexity Factors

  • Differentiation between benign and malignant neoplasms
  • Need for precise documentation of tumor location and characteristics
  • Potential for multiple hormone-secreting tumors
  • Variability in treatment approaches based on tumor staging

Audit Risk Factors

  • Inadequate documentation of hormone levels
  • Failure to specify tumor size and staging
  • Misclassification of benign versus malignant tumors
  • Lack of supporting imaging studies
