Code Description

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

Key Diagnostic Point:

Malignant neoplasms of the adrenal gland are tumors that arise from the adrenal cortex or medulla, which are responsible for producing hormones such as cortisol, aldosterone, and catecholamines. These tumors can disrupt normal hormone production, leading to various endocrine disorders. Common symptoms may include hypertension, weight gain, and abnormal glucose metabolism due to excess cortisol (Cushing's syndrome) or excess catecholamines (pheochromocytoma). Diagnosis typically involves imaging studies such as CT or MRI, along with biochemical tests to assess hormone levels. Treatment often requires surgical intervention, and in some cases, adjuvant therapy may be necessary. The prognosis varies based on tumor size, stage, and the presence of metastasis. Accurate coding is essential for proper reimbursement and tracking of treatment outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in tumor types (e.g., adrenal adenoma vs. carcinoma)
  • Need for precise staging and grading of tumors
  • Potential for multiple hormone-related disorders complicating diagnosis
  • Differentiation from benign adrenal tumors

Audit Risk Factors

  • Inadequate documentation of hormone levels
  • Failure to document imaging studies
  • Misclassification of tumor type (benign vs. malignant)
  • Lack of staging information

Frequently Asked Questions

What are the common symptoms associated with malignant neoplasms of the adrenal gland?

Common symptoms include hypertension, weight gain, abnormal glucose metabolism, and signs of hormonal excess such as Cushing's syndrome or pheochromocytoma.

How is a malignant neoplasm of the adrenal gland diagnosed?

Diagnosis typically involves imaging studies like CT or MRI, along with biochemical tests to assess hormone levels and confirm malignancy through biopsy if necessary.
