Pathological fracture in oth disease, right ulna, init

This code signifies a fracture of the right ulna that occurred due to an underlying disease process, rather than significant trauma. This type of fracture indicates bone fragility or weakness caused by a systemic condition. This specific code is for the initial treatment of this pathological fracture.

Apply this code when documentation clearly indicates a fracture of the right ulna resulting from a disease such as osteoporosis, metastatic cancer, Paget's disease, or osteomalacia. The "A" seventh character specifies that this is the patient's first encounter for active treatment of this fracture.

• Ensure the medical record explicitly states the fracture is pathological and identifies the right ulna as the affected bone.
• Always code the underlying disease causing the pathological fracture first, followed by this code.
• Distinguish from traumatic fractures (S52.x) where the bone was healthy prior to injury.
