Code Description

ICD-10 S82.399 is a billable code used to indicate a diagnosis of other fracture of lower end of unspecified tibia.

Key Diagnostic Point:

The S82.399 code refers to fractures occurring at the lower end of the tibia, which is the larger of the two bones in the lower leg. These fractures can result from various mechanisms, including trauma from falls, sports injuries, or accidents. The lower end of the tibia is critical for knee stability and function, as it articulates with the fibula and forms part of the ankle joint. Fractures in this area can lead to complications such as malunion, nonunion, or post-traumatic arthritis, particularly if associated with ligament injuries. Diagnosis typically involves clinical evaluation and imaging studies, such as X-rays or MRIs, to assess the extent of the fracture and any associated soft tissue damage. Treatment may range from conservative management with immobilization to surgical intervention, including internal fixation or orthopedic reconstructive procedures, depending on the fracture's severity and the patient's overall health. Proper coding is essential for accurate billing and to ensure that the patient receives appropriate care.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in fracture types and associated injuries
  • Need for precise documentation of fracture location and type
  • Potential for associated ligament injuries complicating diagnosis
  • Variations in treatment approaches based on patient demographics

Audit Risk Factors

  • Inadequate documentation of fracture specifics
  • Failure to document associated ligament injuries
  • Misclassification of fracture type or location
  • Inconsistent coding practices across providers

Frequently Asked Questions

What is the difference between S82.399 and S82.30?

S82.399 is used for other fractures of the lower end of the tibia when the specific type is not documented, while S82.30 is for unspecified fractures of the tibia without specifying the location.
