LeFort III fracture, initial encounter for open fracture

This code signifies a severe, complex fracture of the midface, specifically a LeFort III fracture, where the fracture line extends through the nasofrontal sutures, orbital walls, and zygomaticofrontal sutures, separating the entire midface from the cranial base. The "open" designation indicates that there is a break in the skin or mucous membrane communicating with the fracture site.

Apply this code for initial encounters when documentation clearly states a LeFort III fracture with an open wound. This typically occurs following high-impact trauma, such as motor vehicle accidents or severe falls, where the patient presents for initial treatment including reduction and fixation. Documentation must explicitly state "open fracture" or describe a wound communicating with the fracture.

• Ensure documentation specifies "LeFort III" and "open fracture" to support this code.
• Do not confuse with LeFort I or II fractures, which involve different anatomical planes.
• This code is for the initial encounter; subsequent encounters for follow-up care or complications will require different seventh characters.
