Code Description

ICD-10 M84.751 is a billable code used to indicate a diagnosis of incomplete atypical femoral fracture, right leg.

Key Diagnostic Point:

An incomplete atypical femoral fracture refers to a specific type of fracture that occurs in the femur, typically associated with low-energy trauma or stress, often seen in patients with underlying bone density disorders such as osteoporosis. This condition is characterized by a partial fracture of the femur, which may not completely break through the bone cortex. The right leg designation indicates the specific location of the fracture. Atypical femoral fractures are often linked to long-term bisphosphonate therapy for osteoporosis, and they can occur with minimal or no trauma. Patients may present with thigh or groin pain, and radiographic imaging is essential for diagnosis. The incomplete nature of the fracture may lead to delayed healing or complications if not properly managed. Treatment typically involves conservative measures, including rest and pain management, but surgical intervention may be necessary in some cases. Understanding the relationship between bone metabolism, density disorders, and atypical fractures is crucial for effective management and prevention of future fractures.

Frequently Asked Questions

What is the difference between an incomplete and complete atypical femoral fracture?

An incomplete atypical femoral fracture involves a partial break in the bone, while a complete fracture means the bone is fully broken through. Accurate documentation is essential to differentiate between the two for coding purposes.
