Nondisp fx of pisiform, left wrist, subs for fx w nonunion

This code signifies a fracture of the pisiform bone in the left wrist that has not shifted from its normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

This code is appropriate for documenting ongoing treatment of a left pisiform fracture where the bone is not uniting. This includes scenarios such as follow-up appointments for cast changes, physical therapy, or surgical planning for nonunion repair. It should be used after the initial treatment of the fracture.

• Ensure documentation clearly states "left wrist" and "pisiform" to support laterality and specific bone involvement.
• Verify that the fracture is explicitly described as "nondisplaced" and that "nonunion" is documented as the current healing status.
• Do not use this code for initial fracture treatment or for fractures that are healing normally.
