Code Description

ICD-10 M84.756 is a billable code used to indicate a diagnosis of complete transverse atypical femoral fracture, unspecified leg.

Key Diagnostic Point:

A complete transverse atypical femoral fracture is a specific type of fracture that occurs in the femur, characterized by a horizontal break across the bone. These fractures are often associated with low-energy trauma and are commonly seen in patients with underlying bone density disorders, particularly 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 thigh pain, and patients may report a history of prodromal pain prior to the fracture. Diagnosis typically involves imaging studies such as X-rays or MRI to confirm the fracture type and rule out other conditions. Treatment may include surgical intervention, such as intramedullary nailing, and addressing the underlying bone density issues to prevent future fractures. Accurate coding of this condition is crucial for appropriate management and reimbursement.

Medium Complexity

Complexity Factors

  • Requires understanding of atypical fracture characteristics
  • Differentiation from other femoral fractures
  • Association with osteoporosis and bisphosphonate therapy
  • Need for precise documentation of fracture type and location

Audit Risk Factors

  • Inadequate documentation of fracture type
  • Failure to document underlying osteoporosis
  • Misclassification with other fracture codes
  • Lack of imaging reports to support diagnosis
