Nondisp assoc transv/post fx l acetab, 7thK

This code signifies a fracture of the left acetabulum that involves both the transverse and posterior columns, but the bone fragments remain in their anatomical position. The patient is in a subsequent phase of care, and the fracture has failed to heal properly, resulting in a nonunion.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced associated transverse-posterior fracture of the left acetabulum is being treated for a confirmed nonunion. This would include situations where surgical intervention for the nonunion is being planned or performed, or during ongoing management of the unhealed fracture.

• Ensure documentation explicitly states "nondisplaced" and "associated transverse-posterior" for the left acetabulum.
• Verify that the encounter is for a "subsequent" phase of care and that "nonunion" of the fracture is clearly documented.
• Do not use this code for initial encounters or for fractures that are healing normally or with delayed union.
