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

This code signifies a break across the left kneecap that has not shifted out of alignment. The fracture is exposed to the outside environment due to a significant soft tissue injury, indicating a high risk of infection and extensive damage.

Apply this code for a patient presenting with a newly diagnosed, non-displaced transverse fracture of the left patella where the skin and underlying soft tissues are severely compromised, consistent with an open fracture classified as type IIIA, IIIB, or IIIC. This is for the initial treatment encounter for such an injury.

• Ensure documentation clearly specifies "nondisplaced" and "transverse" morphology of the patellar fracture.
• Verify that the open fracture type (IIIA, IIIB, or IIIC) is explicitly stated or clearly inferable from the wound description.
• This code is only for the initial encounter; subsequent care for the same fracture will require a different seventh character.
