Fx unsp phalanx of l idx fngr, subs for fx w malunion

This code describes a situation where a patient has a previously diagnosed fracture of an unspecified phalanx in their left index finger, and the fracture has healed in a misaligned or deformed position. This malunion is being addressed during the current encounter.

This code is appropriate for follow-up visits where a physician is evaluating or treating a malunited fracture of the left index finger's phalanx. This could include assessment for corrective surgery, physical therapy for functional limitations due to the malunion, or monitoring of the malunion's impact.

• Ensure documentation clearly specifies "malunion" and not "nonunion" or "delayed healing."
• Verify the fracture is of the left index finger and an unspecified phalanx (proximal, middle, or distal).
• Confirm this is a subsequent encounter for the fracture, not the initial treatment.
