Nondisp avulsion fracture of unsp ilium, init for opn fx

This code signifies a fracture where a small piece of bone has been pulled away from the main bone of the ilium (the largest part of the hip bone) by a tendon or ligament. The fracture fragments are still in their normal anatomical position (nondisplaced), and the skin and soft tissue overlying the fracture are broken, exposing the bone to the outside environment. This code is specifically for the initial treatment of such an injury when the exact side (left or right) of the ilium is not documented.

Use this code for a patient presenting for the first time with an open avulsion fracture of the ilium where the displacement is not noted, and the laterality is unspecified. This typically occurs due to sudden, forceful muscle contractions or ligamentous stress. It is appropriate for the initial surgical or non-surgical management of the open fracture.

• Requires documentation of an "open" fracture, indicating a break in the skin over the fracture site.
• Only use for the initial encounter; subsequent care will require a different seventh character.
• Avoid using if the laterality (left or right ilium) is specified in the medical record.
