Displ commnt fx shaft of ulna, unsp arm, 7thG

This code signifies a complex fracture of the ulna's shaft, specifically one that is broken into multiple pieces (comminuted) and misaligned (displaced). It indicates that the patient is in a phase of recovery where the fracture is not healing at the expected rate, but is being managed without surgical intervention. The "unspecified arm" component means the laterality of the injury is not documented.

Apply this code for follow-up encounters of a patient with a comminuted and displaced ulnar shaft fracture that is healing slowly after initial closed treatment. This is appropriate when the physician is monitoring the delayed union of the fracture without performing an open reduction or other invasive procedure during the encounter.

• Ensure documentation clearly states "delayed healing" for a closed fracture.
• Verify the fracture is specifically of the ulnar shaft and is both comminuted and displaced.
• Confirm that the encounter is for subsequent care and not the initial treatment.
