Code Description

ICD-10 S82.146 is a billable code used to indicate a diagnosis of nondisplaced bicondylar fracture of unspecified tibia.

Key Diagnostic Point:

A nondisplaced bicondylar fracture of the tibia refers to a fracture that occurs at the proximal end of the tibia, involving both the medial and lateral condyles, without any displacement of the bone fragments. This type of fracture is often associated with high-energy trauma, such as falls or motor vehicle accidents, and can occur in conjunction with ligamentous injuries, particularly to the anterior cruciate ligament (ACL) or the medial collateral ligament (MCL). Patients typically present with knee pain, swelling, and limited range of motion. Diagnosis is confirmed through imaging studies, such as X-rays or MRI, which help assess the extent of the fracture and any associated soft tissue injuries. Treatment may involve conservative management with immobilization or surgical intervention, depending on the stability of the fracture and the presence of additional injuries. Rehabilitation is crucial for restoring function and strength to the knee joint post-injury.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture presentation and associated injuries
  • Need for precise documentation of fracture type and location
  • Potential for concurrent ligament injuries complicating coding
  • Differentiation from other tibial fractures

Audit Risk Factors

  • Inadequate documentation of fracture details
  • Failure to document associated ligament injuries
  • Incorrect coding of fracture displacement
  • Lack of imaging reports to support diagnosis

Specialty Focus

Medical Specialties

Orthopedic Surgery

Documentation Requirements

Detailed operative notes, imaging results, 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 associated injuries, such as ligament tears, are documented to avoid undercoding.

Physical Medicine and Rehabilitation

Documentation Requirements

Comprehensive assessments of functional limitations and rehabilitation progress.

Common Clinical Scenarios

Post-operative rehabilitation following surgical fixation of tibial fractures.

Billing Considerations

Documenting the patient's functional status and rehabilitation goals is crucial for coding.

Frequently Asked Questions

What is the difference between a displaced and nondisplaced bicondylar fracture?

A displaced bicondylar fracture involves a separation of the fracture fragments, while a nondisplaced fracture means the bone fragments remain in alignment.
