Disp 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 failed to heal properly after initial treatment. The fracture fragments are no longer in their anatomical alignment, and there is evidence of nonunion, meaning the bone has not mended. This indicates a persistent problem requiring ongoing management.

This code is appropriate for subsequent encounters when a patient is receiving treatment for a previously diagnosed displaced fracture of the right fifth metacarpal base that has developed nonunion. This includes follow-up visits, cast changes, or preparations for surgical intervention to address the nonunion. It should be used after the initial healing phase has passed without successful bone fusion.

• Ensure documentation clearly states "nonunion" and "displaced" for the right fifth metacarpal base.
• Verify this is a subsequent encounter, not an initial treatment for the fracture.
• Always check for laterality (right hand) and specific bone (fifth metacarpal base).
