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

This code signifies a fracture of the pisiform bone in the right wrist that has not been displaced from its normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "malunion" specifies that the bone has healed, but in an unsatisfactory position or alignment.

This code is appropriate when a patient presents for ongoing treatment, evaluation, or management of a previously diagnosed nondisplaced right pisiform fracture that has healed incorrectly. This includes scenarios where the malunion is being assessed for potential corrective surgery, physical therapy, or other interventions.

• Ensure documentation clearly states "nondisplaced" and specifies the "right wrist" for the pisiform fracture.
• Verify that the encounter is for follow-up care and that the malunion is explicitly documented by the provider.
• Do not use this code for initial treatment of the fracture or for nonunion (failure to heal).
