Oth fx lower end of right tibia, subs for clos fx w malunion

This code signifies a follow-up encounter for a patient who previously sustained a fracture to the lower end of their right tibia, excluding specific malleolar fractures. The key characteristic is that the bone has healed, but in an unsatisfactory position, resulting in a malunion. This indicates a complication of the initial fracture healing process.

Apply this code when documenting subsequent care for a patient with a previously diagnosed, non-malleolar fracture of the distal right tibia that has healed with an angular or rotational deformity. This would include evaluations for pain, functional limitations, or planning for corrective procedures related to the malunion. It is used after the initial healing phase is complete and the malunion has been identified.

• Ensure documentation clearly specifies "right tibia" and "lower end" (distal portion, excluding ankle malleoli).
• Confirm the encounter is for a subsequent visit and that the fracture is closed and has resulted in a malunion.
• Do not use for initial fracture treatment or for nonunion; a malunion implies some degree of healing has occurred.
