Fx unsp phalanx of r little finger, subs for fx w nonunion

This code signifies a non-healing fracture of an unspecified phalanx in the right little finger that the patient is currently receiving care for. Nonunion indicates that the bone ends have failed to unite after a prolonged period, requiring ongoing medical management.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed fracture of the right little finger phalanx that has not healed and is now complicated by nonunion. This would include visits for evaluation, treatment planning for nonunion (e.g., surgery, bone stimulation), or monitoring the progress of nonunion treatment.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" status for the fracture.
• Verify the laterality (right) and the specific digit (little finger) are accurately documented.
• Do not use this code for initial fracture treatment or for fractures that have healed.
