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

This code signifies a specific type of fracture in the ulna bone, located in the forearm. It indicates a break in the shaft of the ulna that is not aligned correctly (displaced) and involves multiple segments. The "malunion" aspect means the fracture has healed, but in an incorrect or deformed position.

This code is appropriate for documenting follow-up care for a closed, segmental ulna shaft fracture that has healed with malunion. It is used when the patient is seen for issues related to this improperly healed fracture, such as pain, limited range of motion, or functional impairment, after the initial treatment phase.

• Ensure documentation clearly states "malunion" and specifies the "shaft" of the ulna.
• Verify this is a "subsequent encounter" for the fracture, not the initial treatment.
• Confirm the fracture was "closed" and "segmental" as per clinical notes.
