Oth fx lower end of left tibia, subs for clos fx w nonunion

This code signifies a non-healing fracture located at the distal end of the left tibia, excluding those specifically classified as pilon or Salter-Harris types. The fracture was initially closed, meaning the skin remained intact, but has failed to unite properly after initial treatment. This diagnosis indicates the patient is receiving ongoing care for this complication.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed closed fracture of the lower end of the left tibia that has developed nonunion. This includes situations where the patient is undergoing further evaluation, conservative management, or surgical intervention to address the non-healing bone. It should be used after the initial treatment phase for the acute fracture.

• Ensure documentation clearly specifies "nonunion" as the complication of the closed distal left tibia fracture.
• Verify that the encounter is for subsequent care, not the initial treatment of the acute fracture.
• Confirm the fracture location is the lower end of the tibia and on the left side, excluding specific pilon or Salter-Harris types.
