Code Description

ICD-10 S52.233 is a billable code used to indicate a diagnosis of displaced oblique fracture of shaft of unspecified ulna.

Key Diagnostic Point:

A displaced oblique fracture of the shaft of the ulna is characterized by a break in the bone that occurs at an angle, resulting in the bone fragments being misaligned. This type of fracture typically arises from high-energy trauma, such as falls or sports injuries, and can be associated with injuries to surrounding soft tissues, including muscles and ligaments. The ulna, one of the two long bones in the forearm, plays a crucial role in forearm stability and wrist function. Displacement of the fracture can lead to complications such as malunion or nonunion, necessitating careful assessment and management. In cases where the fracture is associated with elbow injuries, it is essential to evaluate for potential compartment syndrome, which can occur due to swelling and increased pressure within the muscle compartments of the forearm. Treatment often involves orthopedic fixation procedures, such as internal fixation with plates or screws, to restore alignment and stability, allowing for proper healing and rehabilitation. Accurate coding of this condition is vital for appropriate treatment planning and reimbursement.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture types and locations
  • Need for precise documentation of displacement
  • Potential for associated injuries (e.g., radius fractures)
  • Differentiation from non-displaced fractures

Audit Risk Factors

  • Inadequate documentation of fracture type and displacement
  • Failure to document associated injuries
  • Incorrect coding of the fracture site (ulna vs. radius)
  • Lack of clarity on treatment plan (surgical vs. conservative)

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed operative reports, imaging studies, and follow-up notes are essential to support the diagnosis and treatment plan.

Common Clinical Scenarios

Fractures resulting from falls, sports injuries, or motor vehicle accidents.

Billing Considerations

Ensure that all imaging findings and surgical interventions are clearly documented to support coding.

Emergency Medicine

Documentation Requirements

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

Common Clinical Scenarios

Patients presenting with acute forearm pain and swelling after trauma.

Billing Considerations

Document the mechanism of injury and any immediate interventions performed.
