Nondisp pilon fx right tibia, subs for clos fx w malunion

This code signifies a fracture of the distal tibia (pilon fracture) on the right side that was initially nondisplaced, but has subsequently healed in an imperfect alignment (malunion). The fracture itself is now closed, meaning the skin over the injury remains intact.

Apply this code when documenting follow-up care for a patient whose right tibial pilon fracture, initially nondisplaced, has healed with a noticeable deformity or angulation. This is appropriate for encounters where the malunion is being assessed, monitored, or treated non-surgically after the initial treatment phase.

• Ensure documentation clearly states "malunion" and specifies the right tibia.
• Verify the fracture was initially nondisplaced and is now closed.
• This code is for subsequent encounters, not the initial treatment of the fracture.
