Displaced longitud fx left patella, init for opn fx type I/2

This code signifies a fracture of the left kneecap that runs lengthwise (longitudinal) and is out of its normal alignment (displaced). The fracture has broken through the skin, indicating an open fracture, specifically classified as Type I or Type II according to the Gustilo-Anderson classification.

Use this code for the initial treatment of a patient presenting with a displaced longitudinal fracture of the left patella where the skin integrity has been compromised, exposing the bone. This applies to cases where the open wound is relatively clean with minimal soft tissue damage (Type I) or a moderate open wound with some soft tissue damage (Type II).

• Ensure documentation clearly specifies "displaced" and "longitudinal" for the patellar fracture.
• Confirm the open fracture type (Gustilo-Anderson I or II) is explicitly stated in the medical record.
• This "B" encounter code is only for the initial treatment of the fracture; subsequent encounters will require different seventh characters.
