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

This code signifies a fracture of the distal tibia (pilon fracture) on the left side, which has not shifted out of alignment. The fracture, despite previous treatment, has failed to heal properly, indicating a nonunion. This specific code is used when the patient is receiving ongoing care for this unhealed fracture.

Apply this code when a patient with a previously diagnosed and treated nondisplaced pilon fracture of the left tibia presents for follow-up care, and imaging or clinical assessment confirms that the fracture has not united. This would be appropriate for subsequent clinic visits, imaging studies, or procedures related to managing the nonunion of this closed fracture.

• Ensure documentation clearly states "nondisplaced" and identifies the "left tibia" and "pilon fracture" site.
• Verify that the encounter is for ongoing management of the fracture's nonunion, not initial treatment or routine healing.
• Confirm the fracture is "closed" (skin intact) and the nonunion status is explicitly documented.
