Nondisp avulsion fracture of unsp ischium, init for opn fx

This code signifies a fracture where a small piece of bone has been pulled away from the main bone structure of the ischium due to a tendon or ligament injury, but the bone fragments remain in their normal anatomical position. The fracture is open, meaning there is a break in the skin and soft tissue communicating with the fracture site. This particular code is used for the initial treatment of such an injury when the specific ischial bone (e.g., body, ramus) is not documented.

This code is appropriate for the initial encounter of a patient presenting with an avulsion fracture of an unspecified part of the ischium that is openly exposed to the environment. This would typically be documented by a physician after initial assessment and diagnosis, prior to definitive treatment. It is used when the medical record does not specify whether the avulsion is from the ischial body, ramus, or tuberosity.

• Ensure documentation clearly states "nondisplaced avulsion fracture" and "open fracture" of the ischium.
• Verify that this is the initial encounter for the fracture; subsequent encounters will require a different seventh character.
• If the specific location of the avulsion (e.g., ischial tuberosity, body, ramus) is documented, a more specific code should be selected.
