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

This code signifies a specific type of ulna fracture where the bone is broken in multiple places along the shaft, resulting in a segment of bone being displaced. It indicates that the injury is an open fracture (skin broken, exposing bone) classified as Type I or II, and the patient is in a subsequent phase of care where the healing process is progressing normally. The affected arm is not specified.

Use this code for follow-up encounters or subsequent care for a patient who previously sustained a displaced segmental open fracture (Type I or II) of the ulna shaft, when the physician documents routine healing. This applies when the specific arm (left or right) is not documented.

• Ensure documentation specifies "segmental" and "displaced" for the ulna shaft fracture.
• Verify the open fracture type (I or II) and that the encounter is for subsequent care with routine healing.
• If the arm is specified (left or right), a more specific code should be used.
