Disp fx of distal phalanx of finger, subs for fx w malunion

This code signifies a fracture of the furthest bone in a finger other than the thumb, where the broken bone fragments have healed in an abnormal position (malunion). This specific code is used when the patient is receiving follow-up care for this malunited fracture.

Use this code for patients presenting for treatment of a previously diagnosed distal phalanx fracture of a finger (not the thumb) that has healed incorrectly. This includes scenarios where the patient is undergoing physical therapy, further imaging, or surgical intervention to address the malunion.

• Ensure the documentation clearly states "malunion" and that it's a subsequent encounter for the fracture.
• Verify the specific finger involved is not the thumb, and the fracture is of the distal phalanx.
• Always sequence this code after any primary treatment codes, if applicable, for the current encounter.
