Severely displaced Zone II fx sacrum, subs for fx w nonunion

This code signifies a severe fracture of the sacrum, specifically in Zone II, where the bone fragments are significantly out of alignment. The patient is in a later stage of care for this injury, and the fracture has failed to heal properly, indicating a nonunion.

Apply this code when documenting follow-up care for a patient with a previously diagnosed, severely displaced sacral Zone II fracture that has not united. This is appropriate for subsequent visits where the nonunion is being managed, such as for ongoing pain, delayed healing, or planning for further intervention.

• Ensure documentation clearly states "severely displaced" and "Zone II" for sacral fracture.
• Confirm the encounter is for follow-up care of the fracture and explicitly mentions "nonunion."
• Do not use for initial treatment or for fractures that are healing normally.
