Code Description

ICD-10 C74.0 is a billable code used to indicate a diagnosis of malignant neoplasm of cortex of adrenal gland.

Key Diagnostic Point:

C74.0 refers to a malignant neoplasm originating in the cortex of the adrenal gland, which is responsible for producing hormones such as cortisol, aldosterone, and androgens. These tumors can disrupt normal hormone production, leading to various endocrine disorders. Symptoms may include hypertension, weight gain, and abnormal glucose metabolism due to excess cortisol (Cushing's syndrome) or other hormonal imbalances. Diagnosis typically involves imaging studies such as CT or MRI scans, along with biochemical tests to assess hormone levels. Treatment often requires surgical intervention, and in some cases, adjunctive therapies like chemotherapy or radiation may be necessary. The prognosis can vary significantly based on tumor size, stage at diagnosis, and the presence of metastasis. Accurate coding is essential for proper treatment planning and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between benign and malignant adrenal tumors
  • Understanding the hormonal implications of the neoplasm
  • Variability in clinical presentation and symptoms
  • Need for comprehensive documentation of imaging and lab results

Audit Risk Factors

  • Inadequate documentation of hormone levels
  • Failure to specify the type of malignancy
  • Misclassification of tumor type (benign vs malignant)
  • Lack of imaging study documentation
