Code Description

ICD-10 D35.02 is a billable code used to indicate a diagnosis of benign neoplasm of left adrenal gland.

Key Diagnostic Point:

A benign neoplasm of the left adrenal gland refers to a non-cancerous tumor that arises from the adrenal tissue located on the left side of the body. These neoplasms can include adenomas, which are the most common type, and may produce hormones such as cortisol, aldosterone, or catecholamines, leading to various clinical syndromes. Patients may present with symptoms related to hormone overproduction, such as hypertension, hypokalemia, or Cushing's syndrome. Diagnosis typically involves imaging studies like CT or MRI scans, which help visualize the mass and assess its characteristics. Biochemical tests may also be performed to evaluate hormone levels. Treatment often involves surgical intervention, especially if the neoplasm is symptomatic or shows signs of growth. Regular follow-up and monitoring are essential to ensure that the neoplasm does not progress or lead to complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between benign and malignant adrenal tumors
  • Need for precise documentation of imaging and lab results
  • Potential for hormone-related symptoms complicating the clinical picture
  • Variability in treatment approaches based on tumor size and symptoms

Audit Risk Factors

  • Inadequate documentation of imaging studies
  • Failure to document hormone levels and symptoms
  • Misclassification of benign neoplasm as malignant
  • Lack of follow-up documentation post-treatment
