Code Description

ICD-10 S42.332 is a billable code used to indicate a diagnosis of displaced oblique fracture of shaft of humerus, left arm.

Key Diagnostic Point:

A displaced oblique fracture of the shaft of the humerus is characterized by a break in the bone that occurs at an angle, leading to misalignment of the fractured ends. This type of fracture typically results from high-energy trauma, such as falls or motor vehicle accidents, and can significantly impair arm function. Patients may present with severe pain, swelling, and inability to move the arm. Diagnosis is confirmed through imaging studies, such as X-rays, which reveal the fracture's location and displacement. Treatment often involves orthopedic intervention, which may include closed reduction and immobilization or surgical fixation, depending on the fracture's severity and displacement. Rehabilitation is crucial for restoring function and strength post-injury. Complications can include nonunion, malunion, or nerve injury, particularly to the radial nerve, which runs near the humerus. Proper coding is essential for accurate billing and to ensure appropriate treatment protocols are followed.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of fracture types and classifications
  • Need for precise documentation of displacement and fracture orientation
  • Differentiation from similar codes for non-displaced fractures
  • Potential for associated injuries (e.g., nerve damage) that must be documented

Audit Risk Factors

  • Inadequate documentation of fracture type and displacement
  • Failure to document associated injuries or complications
  • Incorrect coding of laterality (left vs. right)
  • Misinterpretation of imaging results leading to coding errors
