Oth fracture of right ilium, subs for fx w nonunion

This code signifies a non-healing fracture of the right ilium, a large, wing-shaped bone forming the upper and posterior part of the pelvis. "Nonunion" indicates that the bone fragments have failed to unite and heal after a significant period following the initial injury. This diagnosis is made during a follow-up visit after the initial treatment.

This code is appropriate when a patient presents for ongoing management of a previously diagnosed right iliac fracture that has not healed. It should be used for subsequent encounters where nonunion is confirmed or suspected, and the patient is receiving care for this specific complication. This includes visits for evaluation, treatment planning, or intervention related to the nonunion.

• Ensure documentation clearly states "nonunion" and specifies the right ilium.
• Verify this is a subsequent encounter, not the initial treatment for the fracture.
• Do not use this code for malunion; a different code exists for that complication.
