Nondisp fx of dist phalanx of finger, subs for fx w nonunion

This code signifies a fracture of the furthest bone in a finger other than the thumb, where the bone fragments are still in their normal alignment. The fracture has failed to heal properly and the patient is presenting for follow-up care related to this ongoing nonunion.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed nondisplaced distal phalanx fracture of a finger (excluding the thumb) that has not healed as expected. This includes visits for evaluation, management, or treatment of the established nonunion, such as casting changes, physical therapy, or surgical planning.

• Ensure documentation clearly states "nonunion" and the specific finger involved (excluding the thumb).
• Verify the fracture was initially nondisplaced.
• This code is for subsequent encounters, not the initial injury.
