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

This code signifies a fracture of the furthest bone in an unidentifiable thumb that has healed improperly, resulting in a deformity or functional impairment. The patient is presenting for follow-up care related to this malunion.

This code is appropriate for documenting a patient encounter where the primary focus is the management of a previously sustained, displaced distal phalanx thumb fracture that has healed with malunion. This includes assessments, imaging, or discussions regarding corrective procedures for the malunited fracture.

• Ensure documentation clearly specifies "malunion" and the "distal phalanx" of the thumb.
• Verify the encounter is for follow-up care of the fracture, not initial treatment or routine aftercare.
• Laterality (left/right) is unspecified for this particular code; if known, a more specific code should be used.
