Disp fx of base of fifth MC bone, r hand, init for opn fx

This code signifies a break at the base of the fifth metacarpal bone in the right hand, where the bone fragments are no longer in their normal alignment. This specific injury is an open fracture, meaning there is a wound that communicates with the fracture site, and it is being treated for the first time.

Use this code for a patient presenting with an acute, displaced fracture at the base of the little finger's metacarpal bone in the right hand, where the skin has been compromised. This applies to initial treatment encounters, such as emergency room visits or initial surgical interventions for this specific injury.

• Ensure documentation clearly specifies "displaced" and "open fracture" for the base of the fifth metacarpal.
• Verify the laterality is "right hand" to accurately apply this code.
• Confirm this is the initial encounter for treatment of this specific fracture, not a follow-up or subsequent encounter.
