Code Description

ICD-10 M84.361 is a billable code used to indicate a diagnosis of stress fracture, right tibia.

Key Diagnostic Point:

A stress fracture of the right tibia is a small crack in the bone that occurs due to repetitive force or overuse, often seen in athletes or individuals with increased physical activity. This condition is particularly prevalent in those with underlying bone density disorders such as osteoporosis, where the bones are more fragile and susceptible to fractures. The tibia, being a weight-bearing bone, is commonly affected by stress fractures, especially in the lower leg region. Symptoms typically include localized pain that worsens with activity and improves with rest, swelling, and tenderness along the bone. Diagnosis is often confirmed through imaging studies such as X-rays or MRI, which can reveal the fracture line or bone edema. Management includes rest, modification of activities, and in some cases, physical therapy to strengthen surrounding muscles and improve bone health. Understanding the relationship between bone metabolism and stress fractures is crucial, as factors like vitamin D deficiency and hormonal imbalances can exacerbate bone fragility, leading to increased risk of fractures.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and stress fractures
  • Understanding the patient's history of bone density disorders
  • Need for precise documentation of symptoms and imaging results
  • Potential for co-existing conditions affecting bone health

Audit Risk Factors

  • Inadequate documentation of the mechanism of injury
  • Failure to document prior history of osteoporosis or other bone disorders
  • Misclassification of the fracture type (stress vs. acute)
  • Lack of imaging results in the medical record

Frequently Asked Questions

What is the difference between a stress fracture and an acute fracture?

A stress fracture is a small crack in the bone caused by repetitive stress, while an acute fracture is a complete break in the bone typically resulting from a sudden injury.
