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

This code describes a fracture of an unspecified phalanx (bone) in the right little finger that is currently healing with a malunion. A malunion indicates that the fractured bone segments have healed, but in an incorrect or deformed position.

This code is appropriate for encounters where a patient is being treated for a previously diagnosed right little finger phalanx fracture that has healed improperly. This includes follow-up visits for assessment of the malunion, planning for corrective surgery, or management of symptoms related to the malunion.

• Ensure documentation specifies "right little finger" and "malunion" for accurate code assignment.
• This code is for a subsequent encounter, meaning the initial treatment for the fracture has already occurred.
• An additional code for the specific type of malunion (e.g., nonunion, delayed union) may be necessary if further detail is provided.
