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

This code signifies a fracture of the shaft of the fourth metacarpal bone in the left hand that is not displaced. The "G" seventh character indicates that the patient is in a subsequent phase of care, and the fracture is experiencing delayed healing.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed, non-displaced left fourth metacarpal shaft fracture is presenting with evidence of delayed union. This would typically be documented by the physician noting slower-than-expected healing, persistent pain, or radiographic findings indicating incomplete bone consolidation beyond the typical healing timeframe.

• Ensure documentation clearly specifies "delayed healing" for the seventh character "G" to be appropriate.
• Verify the fracture is of the shaft and not the base or head of the metacarpal.
• Confirm laterality (left hand) and that the fracture is nondisplaced.
