Code Description

ICD-10 S42.334 is a billable code used to indicate a diagnosis of nondisplaced oblique fracture of shaft of humerus, right arm.

Key Diagnostic Point:

A nondisplaced oblique fracture of the shaft of the humerus occurs when there is a break in the bone that does not result in the bone fragments being misaligned. This type of fracture is characterized by a diagonal break across the shaft of the humerus, which is the long bone of the upper arm. Such fractures are often caused by trauma, such as falls or direct blows to the arm, and can occur in various populations, including athletes and the elderly. Symptoms typically include pain, swelling, and limited range of motion in the shoulder and arm. Diagnosis is usually confirmed through imaging studies, such as X-rays, which reveal the fracture pattern. Treatment may involve conservative management with immobilization or surgical intervention if the fracture is unstable or associated with other injuries. Rehabilitation is essential for restoring function and strength to the arm following healing.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between displaced and nondisplaced fractures
  • Understanding the specific location of the fracture (shaft vs. proximal/distal)
  • Identifying associated injuries (e.g., rotator cuff tears)
  • Documentation of the mechanism of injury

Audit Risk Factors

  • Inadequate documentation of fracture type
  • Failure to specify laterality (right vs. left)
  • Misclassification of fracture displacement
  • Lack of imaging reports to support diagnosis

Frequently Asked Questions

What is the difference between a displaced and nondisplaced fracture?

A displaced fracture involves a break in the bone where the fragments are misaligned, while a nondisplaced fracture means the bone remains in its normal position despite the break.
