Pathological fracture, pelvis, subs for fx w malunion

This code signifies a pathological fracture of the pelvis that has previously been treated but has healed improperly, resulting in a malunion. This indicates an ongoing issue with the fracture site where the bone fragments have united in a deformed position, requiring continued medical attention.

Apply this code when a patient presents for follow-up care, evaluation, or treatment of a pelvic fracture that has healed incorrectly due to an underlying disease process. Documentation should clearly state "pathological fracture," "pelvis," and "malunion" in the context of a subsequent encounter.

• Ensure documentation specifies "pathological fracture" to differentiate from traumatic fractures.
• Verify the encounter is for follow-up care of the malunion, not initial treatment or routine healing.
• Always sequence this code after the underlying disease causing the pathological fracture, if applicable and still active.
