Complete oblique atypical femoral fracture, left leg, init

This code signifies a complete fracture of the left femur that presents with an atypical oblique pattern, often associated with long-term bisphosphonate use or other metabolic bone disorders. The fracture extends through the entire bone cortex, and its oblique nature distinguishes it from transverse or spiral atypical fractures. This specific code is for the initial treatment phase of the fracture.

Apply this code when documentation clearly indicates a complete, oblique atypical femoral fracture affecting the left leg. This typically occurs in patients with a history of prolonged bisphosphonate therapy or other conditions predisposing to atypical fractures. Documentation should specify the fracture's completeness, obliquity, and laterality, as well as confirm the initial encounter for treatment.

• Ensure documentation specifies "atypical" to differentiate from other femoral fractures.
• Verify laterality (left leg) and encounter type (initial) are clearly stated in the medical record.
• Consider additional codes for underlying conditions contributing to the atypical fracture, such as long-term drug use (e.g., T38.81XA for adverse effect of bisphosphonates).
