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

This code signifies a non-healing fracture located at the distal end of the right tibia, specifically an "other" type of fracture, not further specified as a pilon or Salter-Harris. It indicates that the initial fracture treatment has occurred, but the bone fragments have failed to unite, and the fracture remains closed (skin intact). This represents a complication in the healing process requiring ongoing medical management.

This code is appropriate for follow-up encounters with patients who have previously sustained a closed fracture of the lower right tibia and are now presenting with documented nonunion. It should be used when the patient is receiving continued care for this specific complication, such as for evaluation of nonunion, planning for revision surgery, or ongoing conservative management.

• Ensure documentation clearly states "nonunion" and specifies the "lower end" of the "right tibia."
• Verify the encounter is "subsequent" to the initial fracture treatment.
• Confirm the fracture remains "closed" at the time of this encounter.
