Oth fx lower end of left ulna, init for opn fx type I/2

This code signifies a fracture affecting the distal portion of the left ulna, excluding specific types like Salter-Harris or Torus fractures, where the skin and soft tissue are broken, exposing the bone. The "initial encounter" indicates that the patient is receiving active treatment for this injury.

Apply this code when documenting a newly diagnosed open fracture of the lower end of the left ulna, classified as Gustilo-Anderson Type I or II. This would be used for the initial surgical repair, casting, or other definitive treatment provided at the time of injury.

• Ensure documentation specifies "left" ulna and "lower end" or "distal" ulna.
• Confirm the fracture is explicitly described as "open" and classified as Type I or II.
• This code is only for the initial treatment phase; subsequent encounters will require different seventh characters.
