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

This code signifies a fracture of the distal end of the right tibia (pilon fracture) that is not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "subsequent encounter" indicates the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone is failing to heal properly.

Use this code for patients presenting for ongoing treatment of a previously diagnosed, nondisplaced pilon fracture of the right tibia where the fracture has not united. This would include scenarios such as cast changes, physical therapy, or surgical planning for nonunion, after the initial treatment phase.

• Ensure documentation clearly states "nondisplaced" and "right tibia" for the pilon fracture.
• Verify that the encounter is for follow-up care and that the nonunion status is explicitly documented.
• Do not use for initial treatment of the fracture or for malunion (improperly healed fracture).
