Code Description

ICD-10 M84.759 is a billable code used to indicate a diagnosis of complete oblique atypical femoral fracture, unspecified leg.

Key Diagnostic Point:

A complete oblique atypical femoral fracture is a specific type of fracture that occurs in the femur, characterized by a diagonal break across the bone. This type of fracture is often associated with low-energy trauma, particularly in patients with underlying bone density disorders such as osteoporosis. Osteoporosis is a condition where bones become weak and brittle, increasing the risk of fractures. Atypical femoral fractures are particularly concerning as they can occur with minimal or no trauma, often in patients who are on long-term bisphosphonate therapy for osteoporosis. The fracture may present with localized pain, swelling, and difficulty bearing weight on the affected leg. Diagnosis typically involves imaging studies such as X-rays or MRI to confirm the fracture type and assess for any associated bone pathology. Management may include surgical intervention, such as intramedullary nailing, and addressing the underlying bone density issues to prevent future fractures.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of atypical fracture patterns.
  • Involves knowledge of osteoporosis and its treatment.
  • Differentiation from other types of femoral fractures.
  • Documentation must specify the leg involved.

Audit Risk Factors

  • Inadequate documentation of fracture type.
  • Failure to document underlying osteoporosis.
  • Misidentification of the leg involved.
  • Lack of imaging reports to support diagnosis.
