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

This code describes a situation where a patient has a fracture of the furthest bone in a finger other than the thumb, and the broken bone fragments have healed in an imperfect alignment. This specific code is used when the patient is seen for follow-up care related to this malunion, not for the initial injury.

Use this code for follow-up encounters when a patient presents with a previously diagnosed nondisplaced distal phalanx fracture of a finger (excluding the thumb) that has healed with malunion. This would include visits for assessing the functional impact of the malunion, planning corrective procedures, or monitoring conservative management of the malaligned healing.

• Ensure documentation clearly states "malunion" and specifies "nondisplaced" for the original fracture.
• Verify the fracture location is a distal phalanx of an "other finger" (not the thumb).
• This code is for subsequent encounters; an initial encounter for the fracture would use a different code.
