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

This code describes a fracture of the base of the second metacarpal bone in the right hand that was initially nondisplaced but has since healed incorrectly, resulting in a malunion. The patient is currently receiving care for this specific complication of the fracture.

Apply this code when a patient presents for treatment of a previously sustained, nondisplaced right second metacarpal base fracture that has healed in an anatomically incorrect position. This would typically be used for follow-up visits, physical therapy, or surgical intervention addressing the malunion itself, after the initial healing phase.

• Ensure documentation clearly states "malunion" as a complication of the fracture.
• Verify the fracture location is specifically the base of the second metacarpal and on the right hand.
• This code is for subsequent encounters, not the initial treatment of the acute fracture.
