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

This code signifies a left wrist pisiform bone fracture that was initially nondisplaced but has subsequently healed in an abnormal alignment (malunion). The patient is presenting for follow-up care related to this previously treated fracture with the identified complication.

This code is appropriate when a patient is seen for ongoing management or evaluation of a left pisiform fracture that has healed with malunion. This could include assessment of pain, limited range of motion, or other functional deficits resulting from the malunion, following the initial treatment phase.

• Ensure documentation clearly states "left wrist" and "pisiform" to support laterality and bone specificity.
• Confirm the fracture is described as "nondisplaced" initially and that "malunion" is documented as a complication.
• The "P" seventh character indicates a subsequent encounter for a fracture with malunion, so verify this aligns with the patient's current stage of care.
