Displaced Rolando's fracture, r hand, subs for fx w malunion

This code signifies a previously treated fracture of the base of the thumb's first metacarpal bone (Rolando's fracture) in the right hand, which has healed improperly, resulting in a malunion. The fracture was initially displaced, meaning the bone fragments were not in their normal alignment. This code is used during follow-up care for this specific complication.

This code is appropriate for documenting a patient encounter where a right-hand Rolando's fracture, initially displaced, has healed with a deformity or misalignment. It is used during subsequent visits for ongoing management, evaluation, or treatment of the malunion itself, rather than the initial fracture care. This would include scenarios where the malunion is causing functional impairment or pain.

• Ensure documentation clearly states "malunion" and specifies the right hand and Rolando's fracture.
• Verify the initial fracture was indeed displaced, as this is a specific component of the code.
• This code is for subsequent encounters; do not use it for initial fracture treatment or for nonunion.
