Disp fx of pisiform, right wrist, subs for fx w malunion

This code signifies a right wrist injury involving a pisiform bone fracture that has not healed correctly, resulting in malunion. The fracture fragments are also out of their normal alignment (displaced). This diagnosis indicates the patient is in a subsequent phase of care for this specific fracture.

Use this code when a patient presents for follow-up care of a previously diagnosed right pisiform fracture that has healed in a deformed or misaligned position. This applies to situations where the malunion is confirmed, and the patient is receiving ongoing treatment, evaluation, or management related to this complication.

• Ensure documentation clearly specifies "right wrist" and "pisiform" to differentiate from other carpal bones or laterality.
• Verify that the encounter is for a "subsequent encounter" and that "malunion" is explicitly documented, not just delayed healing.
• Confirm the fracture is "displaced" as this is a specific characteristic of this code.
