Nondisp fx of shaft of 4th MC bone, r hand, 7thP

This code signifies a previously treated fracture of the shaft of the fourth metacarpal bone in the right hand, which has healed in an anatomically incorrect position. Despite the malunion, the bone fragments are still in their original alignment relative to each other, meaning there is no displacement. This indicates a complication of the healing process where the bone has united but with an undesirable angulation or rotation.

This code is appropriate for follow-up encounters where a patient is being treated for a right fourth metacarpal shaft fracture that has healed with malunion. It should be used when the initial fracture treatment is complete, and the focus is now on managing the consequences of the imperfect healing. This may include assessment for functional deficits, pain management, or consideration of corrective procedures.

• Always confirm laterality (right hand) and the specific metacarpal (fourth).
• Ensure documentation clearly states "malunion" and specifies that the fracture was "nondisplaced" initially or at the time of malunion assessment.
• This code is for a "subsequent encounter," meaning it's used after the initial treatment phase for the fracture.
