Displaced dome fx right acetabulum, subs for fx w nonunion

This code describes a specific type of pelvic fracture where the dome of the right acetabulum is broken and the bone fragments are out of alignment. It indicates that the patient is receiving ongoing care for this fracture, and the bone has failed to heal properly after an initial treatment attempt.

Use this code for follow-up encounters with a patient who has a previously diagnosed displaced dome fracture of the right acetabulum, and the physician documents nonunion of the fracture. This includes visits for continued management, evaluation of nonunion, or planning for further intervention due to the lack of healing.

• Ensure documentation clearly specifies "nonunion" and a "subsequent encounter" for the right acetabulum.
• Verify the laterality (right) and the specific fracture site (dome of acetabulum) are accurately documented.
• Do not use this code for initial treatment or for malunion; a different code would be appropriate for those scenarios.
