Nondisp fx of shaft of 4th MC bone, l hand, 7thP

This code signifies a fracture of the shaft of the fourth metacarpal bone in the left hand that has not been displaced. The patient is in a subsequent phase of care, and the fracture has healed in an anatomically incorrect position, resulting in malunion. This indicates a complication of the healing process.

This code is appropriate for documenting follow-up care for a left fourth metacarpal shaft fracture where imaging confirms malunion. It should be used when the patient is receiving ongoing treatment or evaluation for the consequences of this improperly healed fracture. This code is also applicable when planning interventions to correct the malunion.

• Ensure documentation clearly specifies "left hand" and "fourth metacarpal shaft" to support this specific code.
• Verify that "malunion" is explicitly documented by the provider, often supported by radiographic findings.
• Confirm the encounter is for subsequent care, not the initial treatment of the fracture.
