Fx unsp phalanx of l mid finger, subs for fx w malunion

This code signifies a fracture of an unspecified phalanx in the left middle finger that is currently healing with malunion. Malunion indicates that the bone fragments have united in an anatomically incorrect or unsatisfactory position, potentially leading to functional impairment. This encounter is for ongoing care related to this previously diagnosed and treated fracture.

Apply this code when a patient presents for follow-up care of a left middle finger phalanx fracture that has healed, but with a noticeable deformity or angulation. This would include scenarios where the malunion is being monitored, evaluated for potential corrective surgery, or managed conservatively. It is used for subsequent visits after the initial treatment of the fracture.

• Ensure documentation clearly specifies "malunion" and the "subsequent encounter" status.
• Verify the affected finger is the left middle finger and the phalanx is unspecified.
• Do not use for nonunion (failure to heal) or delayed union (healing slower than expected).
