Nondisp dome fx right acetabulum, subs for fx w nonunion

This code describes a specific type of pelvic fracture involving the dome of the right acetabulum, which is the socket part of the hip joint. "Nondisplaced" indicates the bone fragments are still in their normal anatomical alignment. "Subsequent encounter for fracture with nonunion" signifies that the patient is receiving ongoing care for a fracture that has failed to heal properly.

Use this code when documenting follow-up care for a patient with a previously diagnosed nondisplaced dome fracture of the right acetabulum that has not united. This would apply to visits for monitoring, further diagnostic imaging to assess nonunion, or planning for interventions to address the nonunion (e.g., bone grafting, revision surgery). It is used after the initial treatment phase.

• Ensure documentation clearly states "nonunion" and specifies the right acetabulum and dome fracture.
• Verify the encounter is for follow-up care of the nonunion, not an initial injury or a healed fracture.
• Always pair with an external cause code if the cause of the fracture is known and relevant for the encounter.
