Nondisp avulsion fx left ischium, subs for fx w routn heal

This code signifies a follow-up visit for a patient who sustained a fracture where a small piece of bone was pulled away from the main bone of the left ischium, but the bone fragments remain in their normal anatomical position. At this encounter, the fracture is healing as expected without complications.

Apply this code for subsequent encounters when a patient with a previously diagnosed nondisplaced avulsion fracture of the left ischium is receiving routine follow-up care and the fracture is progressing through normal healing stages. This would include appointments for cast changes, physical therapy evaluations during the healing phase, or routine radiographic checks confirming expected union.

• Ensure the encounter is for a subsequent visit and not the initial treatment of the fracture.
• Verify documentation confirms the fracture is nondisplaced and involves the left ischium.
• Confirm that the healing process is routine, without mention of delayed union, nonunion, or malunion.
