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

This code signifies a fracture running lengthwise through the kneecap (patella) that has shifted out of its normal alignment. It specifically indicates an open fracture, meaning the bone has broken through the skin, and is classified as a severe type (IIIA, IIIB, or IIIC) according to the Gustilo-Anderson classification, encountered for the first time.

Apply this code for a patient presenting with an open, displaced longitudinal patellar fracture, where the severity is documented as Gustilo-Anderson type IIIA, IIIB, or IIIC. This code is appropriate for the initial treatment of such an injury, including surgical repair or initial wound management.

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