Displ longitud fx left patella, init for opn fx type 3A/B/C

This code signifies a fracture of the kneecap (patella) that runs lengthwise, is visibly out of alignment, and affects the left knee. It specifically indicates an open fracture where the bone has broken through the skin, categorized as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification, and is being treated for the first time.

Apply this code when documenting the initial treatment of a patient presenting with a left patellar fracture that is both displaced and longitudinal, and where the wound is classified as an open fracture type IIIA, IIIB, or IIIC. This typically involves significant soft tissue damage and contamination.

• Ensure documentation clearly specifies "displaced" and "longitudinal" for the patellar fracture.
• Verify the Gustilo-Anderson classification (IIIA, IIIB, or IIIC) for the open fracture type is explicitly stated in the medical record.
• Confirm this is the patient's initial encounter for this specific injury to use the "C" seventh character.
