Nondisp fx of base of 5th MC bone, r hand, 7thK

This code signifies a fracture at the base of the fifth metacarpal bone in the right hand that has not shifted from its original position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this previously diagnosed fracture, and "nonunion" specifies that the bone fragments have failed to heal together after a reasonable period.

Apply this code when a patient presents for ongoing management of a right fifth metacarpal base fracture that is documented as nondisplaced and has not achieved union. This would include scenarios where surgical intervention for nonunion is being planned or conservative management for nonunion is continuing.

• Ensure documentation clearly states "nondisplaced" and "nonunion" for the right fifth metacarpal base.
• This code is for subsequent encounters, not the initial treatment of the fracture.
• Verify laterality (right hand) is explicitly documented.
