Disp fx of shaft of 4th MC bone, r hand, 7thP

This code signifies a fracture of the shaft of the fourth metacarpal bone in the right hand that has healed incorrectly (malunion). The fracture was displaced at the time of injury, and the patient is now presenting for follow-up care related to this malunited fracture.

This code is appropriate for encounters where a patient is being evaluated or treated for complications arising from a malunited fracture of the right fourth metacarpal shaft. This includes scenarios such as pain, functional limitations, or surgical planning for corrective osteotomy due to the previous fracture's improper healing. It should be used when the initial fracture treatment has concluded, and the current encounter addresses the sequelae of the malunion.

• Ensure documentation clearly states "malunion" and specifies the fourth metacarpal shaft on the right hand.
• Verify that the encounter is for follow-up care related to the malunion, not the initial treatment of the acute fracture.
• Confirm the fracture was initially displaced, as this detail is integral to the code's specificity.
