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

This code signifies a fracture involving both the bone and cartilage of the kneecap (patella) that is no longer in its normal anatomical position. It specifically applies to open fractures, meaning the skin and soft tissues have been significantly compromised, exposing the bone, and are classified as severe (Type IIIA, IIIB, or IIIC). This is the initial encounter for treatment of this injury.

Use this code for a patient presenting with a newly diagnosed, displaced osteochondral fracture of an unspecified patella that is an open fracture of Gustilo-Anderson Type IIIA, IIIB, or IIIC. This would typically be documented in emergency department or initial surgical reports following a traumatic injury.

• Ensure documentation clearly specifies "displaced" and "osteochondral" for the patella.
• Verify the Gustilo-Anderson classification (Type IIIA, IIIB, or IIIC) for the open fracture.
• This code is for the initial encounter; subsequent care would require different encounter codes.
