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

This code signifies a follow-up encounter for a fracture of the neck of the second metacarpal bone in the right hand that was initially nondisplaced but has since healed incorrectly, resulting in a malunion. The malunion indicates that the bone fragments have united in an abnormal position, potentially affecting hand function.

This code is appropriate for subsequent visits where a patient is being treated for complications arising from a previously sustained, nondisplaced fracture of the right second metacarpal neck, specifically when malunion has been diagnosed. This includes encounters for assessment, physical therapy, or surgical planning related to the malunion.

• Always confirm the laterality (right hand) and the specific bone (second metacarpal neck) to ensure accurate coding.
• Verify documentation explicitly states "malunion" and that the encounter is a "subsequent encounter" for the fracture.
• Do not use this code for initial treatment of the fracture or for nonunion, which is a distinct complication.
