Code Description

ICD-10 S42.32 is a billable code used to indicate a diagnosis of transverse fracture of shaft of humerus.

Key Diagnostic Point:

A transverse fracture of the shaft of the humerus is characterized by a break that occurs perpendicular to the long axis of the bone. This type of fracture typically results from direct trauma or a fall onto an outstretched arm. Clinically, patients may present with severe pain, swelling, and limited range of motion in the shoulder and arm. Physical examination often reveals tenderness over the fracture site, and in some cases, deformity may be evident. Diagnostic imaging, particularly X-rays, is essential for confirming the fracture type and assessing for any associated injuries, such as dislocations or damage to surrounding soft tissues. Treatment options vary based on the fracture's stability and the patient's overall health, ranging from conservative management with immobilization to surgical intervention, such as internal fixation. Complications can include nonunion, malunion, or injury to the radial nerve, which may lead to wrist drop. Rehabilitation is crucial for restoring function and strength post-fracture.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between fracture types (transverse vs. oblique vs. spiral)
  • Identifying associated injuries (e.g., nerve damage, dislocations)
  • Variability in treatment approaches (surgical vs. non-surgical)
  • Documentation of fracture specifics (location, displacement)

Audit Risk Factors

  • Inadequate documentation of fracture type and location
  • Failure to document associated injuries or complications
  • Incorrect coding of treatment modalities
  • Lack of clarity in the mechanism of injury

Frequently Asked Questions

What is the difference between S42.32 and S42.31?

S42.32 refers specifically to a transverse fracture of the humerus shaft, while S42.31 indicates an oblique fracture. Accurate coding depends on the fracture type as determined by imaging.
