Displaced longitud fx unsp patella, init for opn fx type I/2

This code signifies a fracture of the kneecap that runs lengthwise (longitudinal) and where the bone fragments are out of alignment (displaced). The fracture has broken through the skin, but the wound is relatively clean and small, indicating a low-energy injury (Type I or II open fracture). This code is used for the initial treatment of such an injury.

Apply this code when documenting the initial encounter for a patient presenting with a displaced longitudinal patellar fracture that has an associated open wound classified as Gustilo-Anderson Type I or II. This would typically be seen in emergency department or initial surgical settings.

• Ensure documentation specifies "displaced" and "longitudinal" for the patellar fracture.
• Confirm the open fracture type is clearly documented as I or II; otherwise, a different open fracture code may be appropriate.
• This code is only for the initial treatment; subsequent encounters will require a different seventh character.
