Displ oblique fx shaft of l ulna, 7thP

This code signifies a left ulnar shaft fracture that is not aligned correctly (oblique and displaced) and has begun to heal in an abnormal position (malunion). This specific code is used when the patient is seen for follow-up care after the initial treatment of this closed fracture.

Apply this code when a patient presents for an office visit, imaging, or other services related to the ongoing management of a previously diagnosed closed oblique fracture of the left ulnar shaft that is now healing with malunion. This is appropriate for subsequent encounters after the initial fracture care has been rendered.

• Ensure documentation clearly states "malunion" and specifies the left ulna and an oblique, displaced fracture of the shaft.
• Verify that this is a subsequent encounter, not the initial treatment encounter for the fracture.
• Confirm the fracture was closed; open fractures would require a different seventh character.
