Nondisp dome fx unsp acetabulum, subs for fx w nonunion

This code signifies a fracture of the dome of the acetabulum that is not displaced, meaning the bone fragments are still in their normal anatomical position. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and the "nonunion" specifies that the bone has failed to heal properly after a typical healing period.

Apply this code when documenting ongoing treatment for a previously diagnosed, nondisplaced acetabular dome fracture that has not united. This includes scenarios where the patient is undergoing further evaluation, conservative management, or surgical intervention specifically to address the nonunion. It is appropriate for follow-up visits after the initial injury has been treated.

• Ensure documentation clearly states "nondisplaced" and specifies the "dome" of the acetabulum.
• Verify that the encounter is for a "subsequent" visit and explicitly mentions "nonunion" of the fracture.
• Do not use this code for initial injury encounters or for fractures that are healing normally.
