Pathological fracture, left humerus, init for fx

This code signifies a fracture of the left humerus that occurred due to an underlying disease process, rather than significant trauma. It indicates that the bone was weakened by a condition, making it susceptible to breaking under normal stress or minor injury. This is the first time the patient is receiving active treatment for this specific fracture.

Apply this code when documentation clearly states a pathological fracture of the left humerus. This typically occurs in patients with conditions like osteoporosis, metastatic cancer, or other bone-weakening diseases. The "A" seventh character is crucial and should be used only for the initial encounter where the patient is receiving active treatment for the fracture.

• Differentiate carefully between pathological fractures and traumatic fractures; the underlying cause dictates the correct code series.
• Ensure the laterality (left humerus) is explicitly documented.
• Confirm the "initial encounter" status; subsequent care for the same fracture will require a different seventh character.
