Disp fx of nk of 5th MC bone, r hand, subs for fx w malunion

This code signifies a previously treated fracture of the neck of the fifth metacarpal bone in the right hand, which has healed incorrectly, resulting in a deformity or functional impairment. The displacement indicates that the bone fragments were not perfectly aligned during the initial healing process. This malunion can lead to persistent pain, reduced range of motion, or cosmetic concerns.

Use this code for follow-up encounters where a patient is being evaluated or treated for complications arising from a malunited fracture of the right fifth metacarpal neck. This includes scenarios such as surgical correction of the malunion, physical therapy for associated functional deficits, or ongoing management of pain related to the deformity.

• Always confirm laterality (right hand) and the specific bone (fifth metacarpal neck).
• Ensure documentation clearly states "malunion" and that this is a subsequent encounter for the fracture.
• Do not use this code for initial fracture treatment or for nonunion, which is a different complication.
