Code Description

ICD-10 S82.021 is a billable code used to indicate a diagnosis of displaced longitudinal fracture of right patella.

Key Diagnostic Point:

A displaced longitudinal fracture of the right patella is characterized by a break in the bone that runs along the length of the patella, resulting in misalignment of the bone fragments. This type of fracture typically occurs due to direct trauma to the knee, such as a fall or a sports-related injury. The displacement of the fracture can lead to significant pain, swelling, and limited range of motion in the knee joint. Patients may present with an inability to bear weight on the affected leg and may exhibit visible deformity or swelling around the knee. Diagnosis is confirmed through imaging studies, primarily X-rays, which reveal the fracture pattern and displacement. Treatment often involves immobilization, pain management, and in some cases, surgical intervention to realign and stabilize the fracture. Rehabilitation is crucial for restoring function and strength to the knee post-injury. The prognosis is generally favorable with appropriate management, although complications such as nonunion or malunion can occur if the fracture is not properly treated.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Specificity of the fracture type (displaced longitudinal)
  • Location of the fracture (right patella)
  • Potential for surgical intervention
  • Need for detailed documentation of injury mechanism

Audit Risk Factors

  • Inadequate documentation of fracture type and displacement
  • Failure to specify laterality (right vs. left)
  • Misclassification of fracture severity
  • Lack of imaging documentation to support diagnosis

Specialty Focus

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 vehicular accidents.

Billing Considerations

Ensure that all surgical interventions and post-operative care are documented to support the coding.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive assessments of functional limitations and rehabilitation progress notes.

Common Clinical Scenarios

Patients undergoing rehabilitation post-fracture repair.

Billing Considerations

Document the patient's functional status and response to therapy for accurate coding.

Frequently Asked Questions

What is the difference between displaced and non-displaced fractures?

Displaced fractures involve a break in the bone where the ends are not aligned, while non-displaced fractures have the bone intact and aligned despite the fracture.
