Nondisp fx of nk of 1st MC bone, r hand, 7thP

This code signifies a previously sustained fracture of the neck of the first metacarpal bone (thumb) in the right hand that was initially nondisplaced. The current encounter addresses a complication where the bone fragments have healed in an abnormal alignment, known as malunion.

This code is appropriate for follow-up visits where a patient is being treated for a malunited fracture of the right thumb's first metacarpal neck. This includes scenarios such as evaluation for corrective surgery, physical therapy addressing the malunion, or ongoing monitoring of the malunited fracture.

• Ensure documentation clearly states "malunion" and specifies the "right hand" and "first metacarpal neck."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code if the fracture is still healing normally or if it has healed completely without malunion.
