Minimally displaced Zone I fx sacrum, subs for fx w nonunion

This code signifies a sacral fracture located in Zone I (ala), which is minimally displaced. The key aspect is that the fracture has not healed as expected, indicating a nonunion, and the patient is presenting for follow-up care related to this ongoing healing issue.

Apply this code when documenting a patient's visit for management of a previously diagnosed minimally displaced Zone I sacral fracture that has failed to unite. This is appropriate for subsequent encounters where the nonunion is being monitored, evaluated, or treated, but not for the initial injury or for a healed fracture.

• Ensure documentation clearly states "nonunion" and specifies the sacral fracture as Zone I and minimally displaced.
• Verify this is a subsequent encounter for the fracture, not the initial treatment.
• Do not use if the fracture is healing normally or has achieved union.
