Path fracture in neoplastic disease, left femur, init

This code signifies a fracture of the left femur that occurred due to weakening of the bone by a neoplastic process, such as a primary or metastatic tumor. The fracture is considered pathological because it was not caused by trauma that would typically break a healthy bone. This specific code indicates the initial treatment or evaluation for this particular fracture.

Apply this code when documentation clearly states a left femoral fracture is secondary to a malignancy, and the patient is presenting for the initial treatment of this fracture. Supporting documentation should include imaging reports confirming the fracture and pathology reports or clinical notes identifying the underlying neoplastic disease. This code is appropriate for inpatient admissions or outpatient visits focused on the acute management of the fracture.

• Always sequence the underlying neoplasm code first, followed by this code for the pathological fracture.
• Ensure documentation specifies "left femur" and "initial encounter" to justify this specific code.
• Distinguish from stress fractures (M84.3x) or other pathological fractures not due to neoplasm (M84.4x).
