Nondisp fx of post column of l acetab, 7thK

This code indicates a fracture of the posterior column of the left acetabulum that has not displaced, meaning the bone fragments are still in their normal anatomical alignment. The "nonunion" aspect signifies that the fracture has failed to heal completely after a typical healing period, and this encounter is for ongoing management of this persistent issue.

This code is appropriate for follow-up encounters where a patient is being treated for a previously diagnosed nondisplaced posterior column acetabular fracture on the left side that has not united. This includes visits for continued conservative management, evaluation for surgical intervention due to nonunion, or monitoring of a nonunion.

• Ensure documentation clearly states "nonunion" and specifies the "posterior column" of the acetabulum.
• Verify the laterality is "left" as specified by the fifth character.
• Confirm this is a "subsequent encounter" for the fracture, not the initial treatment.
