Code Description

ICD-10 S52.04 is a billable code used to indicate a diagnosis of fracture of coronoid process of ulna.

Key Diagnostic Point:

The coronoid process of the ulna is a bony prominence that plays a crucial role in the stability of the elbow joint. A fracture of this structure typically occurs due to a fall on an outstretched hand or direct trauma to the elbow. This injury can lead to significant functional impairment, as it may compromise the stability of the elbow and the integrity of the surrounding ligaments. Patients often present with pain, swelling, and limited range of motion in the elbow. Diagnosis is confirmed through imaging studies, such as X-rays or CT scans, which can reveal the fracture's location and severity. Treatment may involve conservative management with immobilization or surgical intervention, particularly in cases where the fracture is displaced or associated with other injuries, such as fractures of the radial head or associated ligamentous injuries. Surgical fixation may be necessary to restore stability and function to the elbow joint, and rehabilitation is essential for optimal recovery.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of elbow anatomy and biomechanics
  • Differentiation from other types of elbow fractures
  • Potential for associated injuries complicating coding
  • Need for precise documentation of fracture type and treatment

Audit Risk Factors

  • Inadequate documentation of fracture specifics
  • Failure to document associated injuries
  • Incorrect coding of fracture type or location
  • Lack of clarity in treatment plans

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed operative notes, imaging reports, and follow-up assessments 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 performed, and any complications.

Emergency Medicine

Documentation Requirements

Initial assessment notes, imaging results, and treatment provided in the emergency setting.

Common Clinical Scenarios

Patients presenting with acute elbow pain and swelling after trauma.

Billing Considerations

Accurate documentation of mechanism of injury and initial management is crucial for coding.

Inclusion Criteria

Use S52.04 When
  • According to ICD
  • 10 guidelines, S52
  • 04 should be used when the fracture is specifically identified as involving the coronoid process of the ulna
  • Coders must ensure that the documentation supports the diagnosis and that any associated injuries are also coded appropriately

Frequently Asked Questions

What are the common causes of a coronoid process fracture?

Common causes include falls on an outstretched hand, direct trauma to the elbow, or sports-related injuries.

How is a coronoid process fracture treated?

Treatment may involve immobilization for non-displaced fractures or surgical fixation for displaced fractures, often accompanied by rehabilitation.
