Disp fx of r tibial tuberosity, init for opn fx type 3A/B/C

This code describes a specific type of fracture affecting the right tibial tuberosity, which is the bony prominence below the kneecap where the patellar tendon attaches. The fracture is displaced, meaning the bone fragments are not in their normal alignment, and it is an open fracture, indicating a break in the skin exposing the bone. This code is for the initial treatment of a severe open fracture (Gustilo-Anderson type IIIA, IIIB, or IIIC).

Use this code for the initial encounter when a patient presents with a newly diagnosed, displaced, open fracture of the right tibial tuberosity. This applies to cases where the fracture has broken through the skin and is classified as a Gustilo-Anderson type IIIA, IIIB, or IIIC, requiring surgical intervention or initial definitive care.

• Always assign an external cause code to describe the circumstances of the injury.
• Ensure the documentation clearly specifies "displaced" and the Gustilo-Anderson classification for open fractures.
• Verify this is the initial encounter for active treatment; subsequent care would use different encounter codes.
