Oth fracture of unsp ilium, subs for fx w nonunion

This code signifies a fracture of the ilium, the largest bone of the pelvis, that is not specifically classified as another type of iliac fracture. The "subsequent encounter" indicates the patient is receiving routine care during the healing phase, and "nonunion" specifies that the bone is failing to heal properly after the initial injury.

Apply this code when a patient presents for follow-up care of an ill-defined iliac fracture that has not united. This typically involves ongoing management of a previously diagnosed fracture, such as cast changes, physical therapy, or evaluation for surgical intervention due to the nonunion.

• Ensure documentation clearly states "nonunion" and that it's a subsequent encounter for the fracture.
• Confirm the fracture site is the ilium and not another pelvic bone.
• Do not use for initial treatment of a new fracture or for malunion (improper healing).
