Code Description

ICD-10 D13.2 is a billable code used to indicate a diagnosis of benign neoplasm of duodenum.

Key Diagnostic Point:

A benign neoplasm of the duodenum refers to a non-cancerous tumor that arises in the first section of the small intestine, known as the duodenum. These neoplasms can vary in size and may be asymptomatic or present with symptoms such as abdominal pain, nausea, or gastrointestinal obstruction. Common types of benign neoplasms in the duodenum include adenomas, lipomas, and neuroendocrine tumors. While benign, these neoplasms can sometimes lead to complications, such as bleeding or obstruction, necessitating surgical intervention. Surveillance is often recommended, particularly for larger lesions or those with atypical features, as there is a potential for malignant transformation over time. Regular monitoring through imaging studies or endoscopy may be indicated to assess for changes in size or appearance. The management of benign duodenal neoplasms typically involves a multidisciplinary approach, including gastroenterologists and surgeons, to determine the best course of action based on the individual patient's condition and risk factors.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in presentation and symptoms
  • Need for differentiation from malignant neoplasms
  • Potential for malignant transformation requiring surveillance
  • Documentation of size and characteristics of the neoplasm

Audit Risk Factors

  • Inadequate documentation of the neoplasm's characteristics
  • Failure to document surveillance or follow-up plans
  • Misclassification as malignant due to lack of clarity
  • Inconsistent coding across specialties

Frequently Asked Questions

What are the common symptoms of a benign neoplasm of the duodenum?

Common symptoms may include abdominal pain, nausea, vomiting, and gastrointestinal obstruction, although many patients may be asymptomatic.

How often should surveillance be performed for benign duodenal neoplasms?

Surveillance frequency depends on the size and characteristics of the neoplasm, but typically involves regular imaging or endoscopy every 6 to 12 months.
