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

This code signifies a fracture where a small piece of bone has been pulled away from the main bone of the left ischium due to a strong tendon or ligament, but the bone fragments remain in their normal anatomical position. The patient is in a later stage of healing, and the fracture is not progressing as expected, indicating delayed union.

This code is appropriate for follow-up encounters where a patient with a previously diagnosed nondisplaced avulsion fracture of the left ischium is presenting for ongoing management due to delayed healing. This would include situations where imaging shows persistent fracture lines or clinical signs of non-consolidation beyond the typical healing timeframe.

• Ensure documentation clearly specifies "nondisplaced" and "avulsion fracture" of the left ischium.
• Verify that the encounter is for "subsequent care" and explicitly mentions "delayed healing" or a similar phrase indicating a complication of healing.
• Do not use for initial encounters or for fractures that are healing normally.
