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

This code describes a previously treated fracture of the neck of the second metacarpal bone in the left hand that has healed in an anatomically incorrect position, resulting in malunion. The fracture itself was initially nondisplaced, meaning the bone fragments remained in their normal alignment at the time of injury.

Use this code for follow-up encounters where a patient is being treated for complications arising from a malunited fracture of the left second metacarpal neck. This includes scenarios where the malunion is causing pain, functional impairment, or requires further intervention such as corrective surgery.

• Ensure documentation clearly states "malunion" and specifies the left second metacarpal neck.
• Verify the encounter is "subsequent" and not an initial treatment for the fracture.
• Do not use this code if the fracture is still healing normally or if it's a nonunion (failure to heal).
