Code Description

ICD-10 M84.451 is a billable code used to indicate a diagnosis of pathological fracture, right femur.

Key Diagnostic Point:

A pathological fracture of the right femur occurs when the bone breaks due to an underlying disease process rather than from a traumatic injury. This type of fracture is often associated with conditions that weaken bone density, such as osteoporosis, metastatic cancer, or other metabolic bone disorders. In patients with osteoporosis, the structural integrity of the bone is compromised, leading to an increased risk of fractures even with minimal or no trauma. The right femur, being the longest and strongest bone in the body, can be particularly susceptible to fractures in individuals with significant bone density loss. Diagnosis typically involves imaging studies such as X-rays or MRI to confirm the fracture and assess the extent of the underlying bone pathology. Management may include surgical intervention, such as fixation or replacement, alongside treatment of the underlying condition to improve bone health and prevent future fractures. Understanding the etiology of the fracture is crucial for effective treatment and prevention strategies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between traumatic and pathological fractures
  • Identifying underlying conditions contributing to bone weakness
  • Need for precise documentation of fracture type and location
  • Potential for multiple comorbidities affecting treatment

Audit Risk Factors

  • Inadequate documentation of the underlying condition leading to the fracture
  • Failure to specify the type of fracture (e.g., complete vs. incomplete)
  • Incorrect coding of the fracture site or laterality
  • Lack of supporting imaging reports in the medical record

Frequently Asked Questions

What is the difference between a pathological fracture and a traumatic fracture?

A pathological fracture occurs due to underlying bone disease or weakness, while a traumatic fracture results from an external force or injury. Proper documentation is essential to differentiate between the two for accurate coding.
