Nondisp transverse fx unsp acetab, subs for fx w nonunion

This code signifies a transverse fracture of the acetabulum, the socket of the hip bone, that has not shifted out of alignment. The "subsequent encounter" indicates that the patient is receiving follow-up care for this fracture, and "nonunion" specifies that the bone fragments have failed to heal together.

This code is appropriate for documenting ongoing treatment for a previously diagnosed, non-displaced transverse acetabular fracture that has not achieved bony union. This would include scenarios such as continued immobilization, physical therapy, or surgical planning for nonunion repair.

• Ensure documentation clearly states "nondisplaced" and "transverse" for the acetabular fracture type.
• Verify that the encounter is for follow-up care and not the initial treatment of the fracture.
• Confirm that the physician's notes explicitly indicate a diagnosis of nonunion.
