Mult fx of pelv w unstbl disrupt of pelv ring, 7thK

This code signifies a patient presenting with multiple fractures of the pelvis that have resulted in an unstable disruption of the pelvic ring. Crucially, this encounter is for the ongoing management of these fractures, specifically addressing a documented nonunion, meaning the bone fragments have failed to heal together after a previous treatment attempt.

Use this code for follow-up encounters where a patient with previously diagnosed multiple, unstable pelvic ring fractures is being treated for a nonunion. This applies when the physician is actively managing the nonunion, such as planning for revision surgery, monitoring healing progress, or addressing complications related to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies "multiple fractures of the pelvis with unstable disruption of the pelvic ring."
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Always sequence this code after any associated external cause codes, if applicable.
