Disp fx of pisiform, unsp wrist, subs for fx w routn heal

This code signifies a fracture of the pisiform bone in the wrist that is no longer in its anatomical position (displaced). The specific wrist (left or right) is not documented. This code is used during the healing phase after initial treatment, when the fracture is progressing as expected without complications.

This code is appropriate for follow-up encounters where a patient is receiving routine care for a previously diagnosed and treated displaced pisiform fracture. It applies when the physician notes routine healing, such as during cast changes, follow-up X-rays showing callus formation, or physical therapy sessions for uncomplicated recovery.

• Ensure documentation specifies "displaced" and "routine healing" for a pisiform fracture.
• Confirm the encounter is subsequent to the initial treatment, not the initial presentation or an encounter for delayed/nonunion.
• If the laterality (left or right wrist) is documented, a more specific code should be selected.
