Oth fracture of unsp metacarpal bone, subs for fx w malunion

This code signifies a fracture of any metacarpal bone, excluding the thumb, that is currently undergoing treatment for a malunion. A malunion indicates that the bone has healed in an abnormal position, potentially affecting hand function. This code is used for follow-up care after the initial injury.

Use this code for patients presenting for ongoing management of a previously diagnosed metacarpal fracture (not the thumb) where imaging or clinical assessment confirms malunion. This includes scenarios such as follow-up appointments for conservative treatment of the malunion or pre-operative assessments for corrective surgery.

• Ensure documentation clearly specifies "malunion" and that the encounter is subsequent to the initial fracture.
• Verify that the fracture is of a metacarpal bone other than the thumb (first metacarpal).
• Always review the full encounter documentation to confirm the specific metacarpal involved if possible, although this code is for "unspecified."
