Minimally displ Zone III fx sacrum, subs for fx w nonunion

This code signifies a sacral fracture located in Zone III, which involves the sacral ala and sacroiliac joint, with minimal displacement of the bone fragments. The patient is in a subsequent phase of care, and the fracture has failed to heal properly, indicating a nonunion.

This code is appropriate for documenting follow-up encounters for patients with a previously diagnosed minimally displaced Zone III sacral fracture that has not united. This includes situations where the patient is undergoing ongoing treatment for the nonunion, such as further imaging, pain management, or surgical planning for revision.

• Ensure documentation clearly specifies "nonunion" and the "subsequent encounter" for accurate code assignment.
• Verify the fracture location is explicitly documented as Zone III of the sacrum.
• Confirm the displacement is noted as "minimally displaced" to differentiate from other displacement types.
