Type 2 fracture of sacrum, subs for fx w nonunion

This code signifies a sacral fracture that has failed to heal properly, specifically a Type 2 fracture according to the Denis classification, and the patient is presenting for follow-up care related to this nonunion. A Type 2 sacral fracture involves the sacroiliac joint but does not extend into the sacral foramen.

Utilize this code when a patient with a previously diagnosed Type 2 sacral fracture is seen for ongoing management of a confirmed nonunion. This includes visits for evaluation of nonunion, planning for surgical intervention to address nonunion, or conservative management of the unhealed fracture. This code is appropriate for any encounter after the initial treatment phase where nonunion is the primary focus.

• Ensure documentation clearly states "nonunion" and specifies the sacrum as the fracture site.
• Verify the fracture type is indeed Type 2 (involving the sacroiliac joint).
• This "K" seventh character indicates a subsequent encounter for a fracture that has failed to heal.
