Nondisp fx of trapezium, left wrist, init for opn fx

This code signifies a break in the trapezium bone of the left wrist that has not shifted out of its normal anatomical position. Importantly, this fracture involves an open wound, meaning the skin and soft tissue overlying the fracture site have been compromised, exposing the bone to the external environment. This is the initial encounter for treatment of this specific injury.

Use this code for a patient presenting for the first time with a left wrist injury where imaging confirms a nondisplaced fracture of the trapezium. The clinical documentation must clearly indicate an open wound associated with the fracture, such as a laceration or puncture wound communicating with the bone. This code is appropriate for the initial surgical or non-surgical management of the open fracture.

• Ensure documentation specifies "nondisplaced" and "left wrist" for the trapezium fracture.
• Verify the "open fracture" status is clearly documented, often implying a higher risk of infection.
• Confirm this is the "initial encounter" for treatment; subsequent care would use a different encounter character.
