Oth fracture of shaft of left ulna, init for clos fx

This code signifies a closed fracture of the shaft of the left ulna, excluding specific types like Monteggia's or Galeazzi's. It indicates an initial encounter for treatment of a fracture that has not broken through the skin.

Apply this code for patients presenting with a newly diagnosed, non-open fracture of the ulnar shaft on the left arm. This is appropriate for the initial visit where definitive treatment, such as casting or splinting, is initiated.

• Ensure the documentation specifies "left" ulna and "shaft" to differentiate from other forearm bones or ulnar locations.
• Confirm the fracture is explicitly described as "closed" and that this is the patient's "initial encounter" for this specific injury.
• Verify that the fracture type is not otherwise specified as a Monteggia's or Galeazzi's fracture, which have their own distinct codes.
