Code Description

ICD-10 M84.752 is a billable code used to indicate a diagnosis of incomplete atypical femoral fracture, left leg.

Key Diagnostic Point:

An incomplete atypical femoral fracture refers to a specific type of fracture that occurs in the femur, particularly in patients with underlying bone density disorders such as osteoporosis. These fractures are characterized by their atypical nature, often occurring with minimal or no trauma, and are frequently associated with long-term bisphosphonate therapy. The left leg designation indicates the specific limb affected. Clinically, patients may present with thigh pain or discomfort, and imaging studies such as X-rays or MRIs are essential for diagnosis. The incomplete nature of the fracture suggests that the bone has not completely broken through, which may lead to a higher risk of progression to a complete fracture if not managed appropriately. Treatment typically involves conservative management, including pain control and activity modification, although surgical intervention may be necessary in some cases. Understanding the underlying bone metabolism and density disorders is crucial for effective management and prevention of future fractures.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of atypical fracture patterns
  • Involves knowledge of osteoporosis and bone density disorders
  • Documentation must specify laterality (left leg)
  • Potential for misclassification with other fracture types

Audit Risk Factors

  • Inadequate documentation of fracture type
  • Failure to specify laterality
  • Lack of imaging reports to support diagnosis
  • Misdiagnosis as a typical fracture

Specialty Focus

Medical Specialties

Orthopedics

Documentation Requirements

Detailed imaging reports, patient history of osteoporosis, and treatment plans.

Common Clinical Scenarios

Patients presenting with thigh pain after minimal trauma, particularly those on bisphosphonates.

Billing Considerations

Ensure documentation reflects the atypical nature of the fracture and any underlying bone density issues.

Endocrinology

Documentation Requirements

Bone density test results, history of osteoporosis treatment, and metabolic bone disease evaluations.

Common Clinical Scenarios

Patients with a history of osteoporosis presenting with fractures.

Billing Considerations

Document any hormonal treatments or metabolic disorders that may contribute to bone density issues.

Documentation Requirements

Document the reason for the procedure and any imaging findings.

Specialty Considerations

Orthopedic specialists should ensure that the procedure is justified based on clinical findings.

Frequently Asked Questions

What is an atypical femoral fracture?

An atypical femoral fracture is a type of fracture that occurs in the femur with minimal or no trauma, often associated with long-term bisphosphonate therapy and underlying bone density disorders.

How is an incomplete atypical femoral fracture diagnosed?

Diagnosis is made through clinical evaluation, imaging studies such as X-rays or MRIs, and consideration of the patient's history of osteoporosis or bisphosphonate use.

What are the treatment options for an incomplete atypical femoral fracture?

Treatment typically involves conservative management, including pain control and activity modification, although surgical intervention may be necessary in some cases.
