Disp fx of shaft of 1st MC bone, r hand, 7thP

This code signifies a right-hand injury involving a break in the shaft of the first metacarpal bone (thumb), where the bone fragments are no longer properly aligned. This specific code is used when the fracture is healing incorrectly, resulting in a malunion, and the patient is presenting for follow-up care related to this ongoing issue.

This code is appropriate for documenting subsequent encounters for patients who have previously sustained a displaced fracture of the right first metacarpal shaft and are now exhibiting signs of malunion. It should be used when the patient is receiving treatment or evaluation for the complications arising from this improper healing.

• Ensure documentation clearly states "malunion" and specifies the "right hand" and "first metacarpal shaft."
• Verify that the encounter is for follow-up care of the fracture, not the initial treatment.
• Confirm the fracture was initially displaced, as this code is specific to displaced fractures.
