Code Description

ICD-10 S42.33 is a billable code used to indicate a diagnosis of oblique fracture of shaft of humerus.

Key Diagnostic Point:

An oblique fracture of the shaft of the humerus is characterized by a fracture line that runs diagonally across the bone. This type of fracture typically occurs due to a direct blow or a fall onto an outstretched arm, leading to significant pain, swelling, and limited range of motion in the shoulder and arm. Patients may present with visible deformity or abnormal positioning of the arm. Diagnosis is confirmed through imaging studies, such as X-rays, which reveal the fracture's location and orientation. Treatment often involves immobilization with a sling or brace, and in some cases, surgical intervention may be necessary to realign the bone fragments and stabilize the fracture using plates, screws, or intramedullary nails. Rehabilitation is crucial for restoring function and strength to the shoulder and arm post-injury. Complications can include nonunion, malunion, or stiffness of the shoulder joint, which may require further intervention.

Medium Complexity

Complexity Factors

  • Variability in fracture types and locations
  • Need for precise documentation of fracture characteristics
  • Potential for associated injuries (e.g., rotator cuff tears)
  • Differentiation from other humeral fractures

Audit Risk Factors

  • Inadequate documentation of fracture type
  • Failure to document associated injuries
  • Incorrect coding of surgical procedures
  • Misinterpretation of imaging results

Frequently Asked Questions

What is the difference between an oblique fracture and a transverse fracture of the humerus?

An oblique fracture has a diagonal fracture line, while a transverse fracture has a horizontal fracture line. The treatment and implications for healing may differ based on the fracture type.
