Fracture of unsp carpal bone, left wrist, init for opn fx

This code signifies a break in one of the eight carpal bones of the left wrist, where the skin and underlying tissue are compromised, exposing the fracture site. This injury is in its initial phase of treatment.

Apply this code for a patient presenting with a newly diagnosed, open fracture of any carpal bone in the left wrist. This is appropriate when the specific carpal bone involved has not yet been identified or documented.

• Ensure documentation clearly states "open fracture" and specifies the left wrist.
• If the specific carpal bone is identified (e.g., scaphoid, lunate), a more specific code should be used.
• Confirm this is the initial encounter for treatment of the fracture, not a subsequent visit.
