Nondisp fx of shaft of 2nd MC bone, l hand, 7thP

This code signifies a previously treated fracture of the shaft of the second metacarpal bone in the left hand, which has healed in an anatomically incorrect position (malunion). The fracture itself is not displaced, meaning the bone fragments are still aligned end-to-end, but the overall alignment of the bone is compromised. This diagnosis indicates the patient is receiving ongoing care for the complications arising from this malunion.

Apply this code when a patient presents for follow-up care, evaluation, or treatment related to a malunited fracture of the left second metacarpal shaft. This includes scenarios where the malunion is causing pain, functional impairment, or is being assessed for corrective surgery. It is used after the initial fracture treatment has concluded and the malunion has been identified.

• Ensure documentation clearly states "malunion" and specifies the "second metacarpal shaft" and "left hand."
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment or a new injury.
• Confirm the fracture is described as "nondisplaced" at the time of the original injury.
