Disp fx of post column of l acetab, subs for fx w routn heal

This code signifies a follow-up encounter for a patient who previously sustained a fracture of the posterior column of the left acetabulum, specifically the ilioischial portion, which was displaced at the time of injury. The current encounter indicates that the fracture is healing routinely without complications.

This code is appropriate for subsequent visits where a patient with a previously diagnosed and treated displaced fracture of the left acetabular posterior column is being monitored for normal healing progress. It would be used for routine follow-up appointments, cast changes, or imaging reviews confirming expected bone consolidation.

• Ensure the documentation specifies "left" acetabulum and "posterior column [ilioischial]" to match the code's specificity.
• Confirm the encounter is for "routine healing" and not for delayed healing, nonunion, or malunion, which would require different seventh characters.
• Verify that the initial injury was indeed a "displaced" fracture; otherwise, a different code for a non-displaced fracture would be more appropriate.
