Code Description

ICD-10 M84.757 is a billable code used to indicate a diagnosis of complete oblique atypical femoral fracture, right leg.

Key Diagnostic Point:

A complete oblique atypical femoral fracture refers to a specific type of fracture that occurs in the femur, characterized by an oblique fracture line that is not typical of standard traumatic fractures. This type of fracture is often associated with low-energy trauma, particularly in patients with underlying bone density disorders such as osteoporosis. The atypical nature of the fracture suggests that it may be related to long-term bisphosphonate therapy or other medications that affect bone metabolism. Patients with osteoporosis have compromised bone density, making them more susceptible to fractures even with minimal trauma. The right leg designation indicates the specific limb affected, which is crucial for accurate coding and treatment planning. Management typically involves surgical intervention, such as internal fixation, and rehabilitation to restore function and prevent future fractures. Understanding the underlying causes, such as osteoporosis, is essential for comprehensive patient care and prevention strategies.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Requires understanding of atypical fracture patterns.
  • Involves knowledge of osteoporosis and its treatment implications.
  • Documentation must specify the type and location of the fracture.
  • Differentiation from other femoral fractures is necessary.

Audit Risk Factors

  • Inadequate documentation of fracture type and location.
  • Failure to document underlying conditions like osteoporosis.
  • Misclassification of fracture as typical rather than atypical.
  • Lack of clarity on the mechanism of injury.

ICD-10 Impact

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of atypical fractures, improving the ability to track and manage conditions related to osteoporosis and medication effects. This specificity aids in better patient management and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of atypical fractures, improving the ability to track and manage conditions related to osteoporosis and medication effects. This specificity aids in better patient management and resource allocation.

Frequently Asked Questions

What is an atypical femoral fracture?

An atypical femoral fracture is a specific type of fracture that occurs in the femur, often associated with low-energy trauma and linked to medications like bisphosphonates used in osteoporosis treatment. These fractures have distinct radiographic features and occur in patients with compromised bone density.
