Severely displ Zone III fx sacrum, subs for fx w delay heal

This code signifies a severe break in the lower part of the sacrum (Zone III), where the bone fragments are significantly out of alignment. It specifically indicates that the patient is in a later stage of care for this fracture, and the healing process is taking longer than expected.

This code is appropriate for follow-up encounters when a patient with a previously diagnosed, severely displaced sacral Zone III fracture is experiencing delayed union or nonunion. It should be used when the physician is actively managing the prolonged healing of this specific injury.

• Always ensure documentation clearly specifies "severely displaced" and "Zone III" for sacral fractures.
• Verify that the encounter is for subsequent care and that "delayed healing" is explicitly documented.
• Do not use for initial fracture treatment or for routine follow-up of a normally healing fracture.
