Displ seg fx shaft of ulna, unsp arm, 7thB

This code signifies a break in the shaft of the ulna bone, which is one of the two long bones in the forearm. The fracture is characterized by multiple fragments (segmental) and the bone pieces are not in their normal alignment (displaced). It specifically applies to an open fracture where the skin is broken, classified as Type I or Type II, and is being treated for the first time.

Use this code for a patient presenting with an open, segmental, and displaced fracture of the ulnar shaft, where the arm involved is not specified (e.g., documentation states "ulna fracture" without laterality). This code is appropriate for the initial treatment of the open fracture, such as debridement, irrigation, and initial stabilization.

• Ensure documentation clearly specifies "segmental" and "displaced" for the ulnar shaft fracture.
• Verify the open fracture type is documented as Type I or Type II for appropriate classification.
• Confirm this is the initial encounter for treatment; subsequent encounters will require a different seventh character.
