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

This code signifies a fracture of the first bone of the right thumb that is not displaced, meaning the bone fragments are still in their normal alignment. The "subsequent encounter" indicates the patient is receiving ongoing treatment for this fracture, and "nonunion" specifies that the bone is failing to heal properly after the expected healing period.

Use this code for follow-up visits where a patient is being treated for a right thumb proximal phalanx fracture that has not healed. This would include scenarios where the physician is monitoring the nonunion, discussing further treatment options (e.g., surgery, bone stimulation), or managing complications related to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right thumb's proximal phalanx.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code if the fracture is displaced or if it is a different phalanx or finger.
