Code Description

ICD-10 S52.042 is a billable code used to indicate a diagnosis of displaced fracture of coronoid process of left ulna.

Key Diagnostic Point:

A displaced fracture of the coronoid process of the ulna is a specific type of elbow fracture that occurs at the bony prominence on the ulna, which is crucial for the stability of the elbow joint. This injury often results from a fall onto an outstretched hand or a direct blow to the elbow. The coronoid process serves as an attachment point for ligaments and plays a significant role in the stability of the elbow, particularly in flexion. Displacement of the fracture can lead to instability in the joint, necessitating careful evaluation and management. Symptoms typically include pain, swelling, and limited range of motion in the elbow. Diagnosis is confirmed through imaging studies, such as X-rays or CT scans, which reveal the fracture's location and displacement. Treatment may involve conservative management with immobilization or surgical intervention, particularly if the fracture is significantly displaced or associated with other injuries, such as a fracture of the radial head or ligamentous injuries. Surgical fixation may involve the use of plates and screws to stabilize the fracture and restore function.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of elbow anatomy and biomechanics.
  • Differentiation from similar fractures (e.g., radial head fractures).
  • Potential for associated injuries complicating coding.
  • Need for precise documentation of displacement and treatment approach.

Audit Risk Factors

  • Inadequate documentation of fracture type and displacement.
  • Failure to document associated injuries.
  • Incorrect coding of laterality (left vs. right).
  • Lack of clarity in treatment plan and follow-up.

Documentation Requirements

Detailed operative reports, imaging studies, and follow-up notes are essential for accurate coding.

Common Clinical Scenarios

Fractures resulting from sports injuries, falls, or trauma requiring surgical intervention.

Billing Considerations

Documentation must clearly indicate the type of fracture, treatment provided, and any complications.

Emergency Medicine

Documentation Requirements

Initial assessment notes, imaging results, and treatment plans must be documented thoroughly.

Common Clinical Scenarios

Patients presenting with acute elbow pain following trauma.

Billing Considerations

Timely documentation is critical for coding accuracy, especially in acute settings.

Frequently Asked Questions

What is the significance of the coronoid process in elbow stability?

The coronoid process is essential for maintaining the stability of the elbow joint, particularly during flexion and extension. Fractures in this area can lead to joint instability and functional impairment.
