Displ transverse fx l patella, init for opn fx type 3A/B/C

This code signifies a fracture of the left kneecap that has shifted out of its normal alignment. It specifically indicates an open fracture, meaning the skin and soft tissues have been significantly damaged, exposing the bone to the outside environment, and is classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification. This code is used for the initial treatment phase of such an injury.

Apply this code for patients presenting with a newly diagnosed, displaced transverse fracture of the left patella that meets the criteria for a Gustilo-Anderson Type IIIA, IIIB, or IIIC open fracture. This code is appropriate for the initial surgical repair, debridement, or other definitive treatment during the acute phase of the injury. Do not use this code for subsequent encounters for routine healing or follow-up care.

• Confirm the fracture is explicitly documented as "displaced" and "transverse" for the left patella.
• Verify documentation clearly states the open fracture type as IIIA, IIIB, or IIIC according to Gustilo-Anderson classification.
• Ensure this is the patient's initial encounter for this specific injury; subsequent care will require a different encounter character.
