Code Description

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

Key Diagnostic Point:

C74.10 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 crucial role in the body's response to stress, regulating heart rate, blood pressure, and metabolic processes. Tumors in this area can lead to excessive hormone production, resulting in symptoms such as hypertension, palpitations, and anxiety. The diagnosis of a malignant neoplasm in this region often requires imaging studies, such as CT or MRI, and may involve biopsy for definitive histological diagnosis. Treatment typically includes surgical resection, and in some cases, adjunctive therapies such as chemotherapy or radiation may be indicated. The prognosis depends on the tumor's size, stage, and the presence of metastasis. Accurate coding is essential for proper treatment planning and reimbursement, as well as for tracking outcomes in patients with this rare but serious condition.

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiation between benign and malignant neoplasms
  • Need for precise anatomical localization
  • Potential for multiple hormone-secreting tumors
  • Variability in clinical presentation and symptoms

Audit Risk Factors

  • Inadequate documentation of tumor characteristics
  • Failure to specify the site of the neoplasm
  • Lack of supporting imaging or pathology reports
  • Misclassification of tumor type (benign vs malignant)
