Code Description

ICD-10 D13.39 is a billable code used to indicate a diagnosis of benign neoplasm of other parts of small intestine.

Key Diagnostic Point:

Benign neoplasms of the small intestine are non-cancerous tumors that can occur in various parts of the small intestine, including the duodenum, jejunum, and ileum. These neoplasms can be classified into several types, including adenomas, lipomas, and neurofibromas, among others. While benign, these tumors can still cause significant clinical symptoms, such as obstruction, bleeding, or abdominal pain, depending on their size and location. Diagnosis typically involves imaging studies like CT scans or MRIs, and sometimes endoscopic procedures for direct visualization and biopsy. Surveillance is crucial, as some benign neoplasms may have the potential to undergo malignant transformation over time, necessitating regular monitoring. Treatment options may include surgical resection if symptomatic or if there is concern for malignancy. Understanding the nature of these neoplasms and their management is essential for appropriate coding and patient care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of benign neoplasm types requiring specific documentation.
  • Potential for malignant transformation necessitating careful monitoring.
  • Differentiation from malignant neoplasms in coding.
  • Need for precise anatomical localization in documentation.

Audit Risk Factors

  • Inadequate documentation of the neoplasm type.
  • Failure to document surveillance or follow-up plans.
  • Misclassification as malignant due to similar symptoms.
  • Lack of clarity on the anatomical location of the neoplasm.

Frequently Asked Questions

What is the difference between benign and malignant neoplasms?

Benign neoplasms are non-cancerous growths that do not invade surrounding tissues or metastasize, while malignant neoplasms are cancerous and can spread to other parts of the body.
