Path fracture in oth disease, r hand, subs for fx w nonunion

This code signifies a fracture of the right hand that occurred due to an underlying disease process, not from trauma. The fracture has failed to heal properly, resulting in a nonunion, and the patient is presenting for follow-up care related to this unhealed fracture.

Use this code when documentation specifies a pathological fracture of the right hand that has not united, and the patient is seen for ongoing treatment or assessment of this nonunion. This typically applies to patients with conditions like osteoporosis, metastatic cancer, or Paget's disease, where the bone is inherently weakened.

• Always verify the laterality (right hand) and the specific type of fracture (pathological) from the documentation.
• Ensure the "K" seventh character for subsequent encounter with nonunion is supported by the patient's current visit purpose.
• Code the underlying disease causing the pathological fracture first, followed by this code.
