Disp fx of unsp tibial tuberosity, init for opn fx type I/2

This code signifies a displaced fracture of the tibial tuberosity, the bony prominence on the front of the tibia just below the knee, where the patellar tendon attaches. "Displaced" indicates that the bone fragments are not in their normal alignment. This specific code is for an open fracture, meaning the skin and soft tissues are broken, exposing the bone, and is further classified as Type I or II according to the Gustilo-Anderson classification.

Use this code for initial encounters when documenting an acute, displaced open fracture of the tibial tuberosity (Type I or II). This typically occurs following direct trauma to the knee or a forceful contraction of the quadriceps muscle. It is appropriate for the initial treatment phase, including evaluation, surgical repair, or casting.

• Ensure the documentation clearly specifies "displaced" and "open fracture type I or II" of the tibial tuberosity.
• Remember to also code any associated external cause of injury and place of occurrence codes.
• This code is for the initial encounter; subsequent encounters for routine healing or malunion/nonunion will require different codes.
