Nondisp fx of shaft of 4th MC bone, r hand, 7thK

This code signifies a previously diagnosed fracture of the shaft of the fourth metacarpal bone in the right hand that has failed to heal properly. The fracture fragments remain in their anatomical alignment, but the bone has not united after the expected healing period. This indicates a complication in the healing process requiring ongoing management.

This code is appropriate for documenting follow-up encounters for a patient with a right fourth metacarpal shaft fracture where imaging or clinical assessment confirms nonunion. It should be used when the patient is receiving continued treatment for this specific complication, such as non-surgical interventions or planning for surgical repair of the nonunion.

• Ensure documentation clearly specifies "nonunion" and the specific metacarpal bone (fourth) and side (right).
• Verify the fracture is of the "shaft" and remains "nondisplaced" to accurately apply this code.
• Pair with appropriate procedure codes for any interventions performed to address the nonunion.
