Nondisp fx of prox phalanx of r thm, subs for fx w malunion

This code signifies a fracture of the first bone of the right thumb, closest to the hand, that was not displaced at the time of injury. The current encounter addresses a complication where the fracture has healed in an abnormal alignment, known as malunion. This indicates ongoing management or assessment of the malunion after the initial treatment phase.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a malunited fracture of the right thumb's proximal phalanx. This includes scenarios where surgical correction of the malunion is being planned or performed, or when conservative management of the malunion is ongoing. It is used after the initial healing period, when the fracture has already united, albeit incorrectly.

• Ensure documentation clearly states "malunion" and specifies the right thumb's proximal phalanx.
• Verify that the original fracture was nondisplaced, as this is a specific characteristic of the code.
• This code is for a subsequent encounter, meaning it's not for the initial treatment of the fracture.
