Displaced comminuted fx shaft of ulna, right arm, init

This code signifies a severe break in the shaft of the right ulna, where the bone is broken into multiple fragments and the broken ends are not in their normal anatomical alignment. This type of fracture often results from significant trauma and requires careful management due to its complexity.

Apply this code for initial encounters when documenting a comminuted fracture of the right ulnar shaft that is clearly displaced. This is appropriate for the first time a patient is seen for this specific injury, prior to definitive treatment or during the acute phase of care.

• Ensure documentation specifies "right arm" and "ulna" to differentiate from other forearm bones or sides.
• Confirm the fracture is described as "comminuted" and "displaced" to support the specificity of this code.
• The "A" suffix indicates an initial encounter for a closed fracture; use subsequent encounter codes for follow-up care.
