Displaced dome fx left acetabulum, subs for fx w nonunion

This code signifies a fracture of the dome of the left acetabulum that is no longer in its anatomical position. The fracture has failed to heal properly after an initial treatment, indicating a nonunion, and the patient is presenting for follow-up care related to this ongoing issue.

Apply this code when documenting a patient visit for management of a previously treated displaced left acetabular dome fracture that has not united. This includes scenarios such as evaluation for surgical intervention for nonunion, follow-up imaging to assess nonunion status, or ongoing pain management related to the unhealed fracture.

• Ensure documentation clearly states "nonunion" and "subsequent encounter" for the fracture.
• Verify the laterality is specifically "left" and the fracture site is the "dome of the acetabulum."
• Do not use this code for initial treatment of the fracture or for malunion; a different seventh character would be appropriate.
