Displ osteochon fx unsp patella, init for opn fx type I/2

This code signifies a fracture involving both bone and cartilage of the kneecap, where the fractured fragments are not properly aligned. The specific patella is not documented, and this code is used for the initial treatment of an open fracture classified as Type I or Type II according to the Gustilo-Anderson classification.

This code is appropriate for the initial encounter when a patient presents with an open, displaced osteochondral fracture of an unspecified patella. This includes scenarios where the skin has been broken, exposing the fracture site, and the wound is relatively clean (Type I) or has moderate soft tissue damage (Type II).

• Ensure documentation clearly states "displaced" and "open fracture type I or II" for the patella.
• Verify if the specific patella (left or right) is documented; if so, a more specific code should be used.
• This code is for the initial treatment phase; subsequent encounters will require different seventh characters.
