Disp fx of shaft of 5th MC bone, r hand, 7thP

This code signifies a fracture of the shaft of the fifth metacarpal bone in the right hand that has healed improperly, resulting in a malunion. This specific code is used when the patient is receiving follow-up care for this previously treated fracture that has now developed a deformity due to incorrect alignment during healing.

Apply this code for patients presenting for evaluation or treatment of a right fifth metacarpal shaft fracture that has healed in a misaligned position. This would include scenarios where a patient is seen for pain, functional limitations, or cosmetic concerns directly related to the malunion of this specific fracture. It is appropriate for subsequent encounters after the initial treatment of the fracture.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed union."
• Verify the fracture location is the shaft of the fifth metacarpal and on the right hand.
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
