Nondisp fx of base of 3rd MC bone, r hand, 7thP

This code describes a right-hand injury involving a metacarpal fracture at the base of the third digit, specifically a nondisplaced break that is now healing improperly. "Malunion" indicates that the bone fragments have united in a position that is anatomically incorrect, potentially leading to functional impairment. This is a follow-up encounter, meaning the initial injury has already been addressed.

Use this code for a patient presenting for ongoing management or evaluation of a previously treated nondisplaced fracture of the base of the right third metacarpal, where imaging or clinical assessment confirms malunion. This would apply to follow-up appointments, physical therapy sessions, or surgical consultations related to the malunited fracture.

• Ensure documentation clearly states "malunion" and specifies the right hand and third metacarpal base.
• Verify that this is a subsequent encounter, not the initial treatment for the fracture.
• Always review operative reports or imaging results to confirm the nondisplaced nature of the original fracture and the presence of malunion.
