Disp fx of base of 2nd MC bone, r hand, 7thP

This code signifies a fracture at the base of the second metacarpal bone in the right hand that has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment. This specific code is used when the patient is receiving follow-up care for this previously treated fracture that has now healed in a misaligned position.

Apply this code when a patient presents for evaluation or treatment of a right second metacarpal base fracture that has already undergone initial treatment but has healed with a noticeable deformity or functional impairment due to malunion. This would include scenarios where a surgeon is assessing the malunion for potential corrective surgery or managing ongoing symptoms related to the improper healing.

• Ensure documentation clearly states "malunion" and specifies the "subsequent encounter" for the fracture.
• Verify the laterality (right hand) and the specific bone (second metacarpal base) are accurately documented.
• Distinguish from nonunion (failure to heal) or routine follow-up for a healing fracture without malunion.
