Disp fx of unsp tibial tuberosity, init for clos fx

This code signifies a break in the bony prominence located at the top front of the shin bone (tibia), where the patellar tendon attaches. The fracture fragments are not in their normal anatomical alignment, and the injury is being treated for the first time without an open wound communicating with the fracture site.

Apply this code for initial encounters involving a closed fracture of the tibial tuberosity where the specific location (e.g., right or left) is not documented. This is commonly seen in adolescents due to forceful quadriceps contraction, often during sports activities.

• Ensure documentation specifies "displaced" and "closed" for accurate code assignment.
• Only use the "A" seventh character for the initial treatment of the fracture.
• If laterality (left or right) is documented, a more specific code should be chosen.
